What are the top 3 methods used to find Autoregressive Parameters in Data Science?
In order to find autoregressive parameters, you will first need to understand what autoregression is. Autoregression is a statistical method used to create a model that describes data as a function of linear regression of lagged values of the dependent variable. In other words, it is a model that uses past values of a dependent variable in order to predict future values of the same dependent variable.
In time series analysis, autoregression is the use of previous values in a time series to predict future values. In other words, it is a form of regression where the dependent variable is forecasted using a linear combination of past values of the independent variable. The parameter values for the autoregression model are estimated using the method of least squares.
The autoregressive parameters are the coefficients in the autoregressive model. These coefficients can be estimated in a number of ways, including ordinary least squares (OLS), maximum likelihood (ML), or least squares with L1 regularization (LASSO). Once estimated, the autoregressive parameters can be used to predict future values of the dependent variable.
To find the autoregressive parameters, you need to use a method known as least squares regression. This method finds the parameters that minimize the sum of the squared residuals. The residual is simply the difference between the predicted value and the actual value. So, in essence, you are finding the parameters that best fit the data.

How to Estimate Autoregressive Parameters?
There are three main ways to estimate autoregressive parameters: ordinary least squares (OLS), maximum likelihood (ML), or least squares with L1 regularization (LASSO).
Ordinary Least Squares: Ordinary least squares is the simplest and most common method for estimating autoregressive parameters. This method estimates the parameters by minimizing the sum of squared errors between actual and predicted values.
Maximum Likelihood: Maximum likelihood is another common method for estimating autoregressive parameters. This method estimates the parameters by maximizing the likelihood function. The likelihood function is a mathematical function that quantifies the probability of observing a given set of data given certain parameter values.
Least Squares with L1 Regularization: Least squares with L1 regularization is another method for estimating autoregressive parameters. This method estimates the parameters by minimizing the sum of squared errors between actual and predicted values while also penalizing models with many parameters. L1 regularization penalizes models by adding an extra term to the error function that is proportional to the sum of absolute values of the estimator coefficients.
Finding Autoregressive Parameters: The Math Behind It
To find the autoregressive parameters using least squares regression, you first need to set up your data in a certain way. You need to have your dependent variable in one column and your independent variables in other columns. For example, let’s say you want to use three years of data to predict next year’s sales (the dependent variable). Your data would look something like this:
| Year | Sales |
|——|——-|
| 2016 | 100 |
| 2017 | 150 |
| 2018 | 200 |

For our sales example, that calculation would look like this:
$$ \operatorname {Var} (Y)=\sum _{i=1}^{3}\left({y_{i}}-{\bar {y}}\right)^{2}=(100-150)^{2}+(150-150)^{2}+(200-150)^{2})=2500 $$
and
$$ \operatorname {Cov} (X,Y)=\sum _{i=1}^{3}\left({x_{i}}-{\bar {x}}\right)\left({y_{i}}-{\bar {y}}\right)=(2016-2017)(100-150)+(2017-2017)(150-150)+(2018-2017)(200-150))=-500 $$
Now we can finally calculate our autoregressive parameters! We do that by solving this equation:
$$ \hat {\beta }=(X^{\prime }X)^{-1}X^{\prime }Y=\frac {1}{2500}\times 2500\times (-500)=0.20 $$\.20 . That’s it! Our autoregressive parameter is 0\.20 . Once we have that parameter, we can plug it into our autoregressive equation:
$$ Y_{t+1}=0\.20 Y_t+a_1+a_2+a_3footnote{where $a_1$, $a_2$, and $a_3$ are error terms assuming an AR(3)} .$$ And that’s how you solve for autoregressive parameters! Of course, in reality you would be working with much larger datasets, but the underlying principles are still the same. Once you have your autoregressive parameters, you can plug them into the equation and start making predictions!.
Which Method Should You Use?
The estimation method you should use depends on your particular situation and goals. If you are looking for simple and interpretable results, then Ordinary Least Squares may be the best method for you. If you are looking for more accurate predictions, then Maximum Likelihood or Least Squares with L1 Regularization may be better methods for you.
Autoregressive models STEP BY STEP:
1) Download data: The first step is to download some data. This can be done by finding a publicly available dataset or by using your own data if you have any. For this example, we will be using data from the United Nations Comtrade Database.
2) Choose your variables: Once you have your dataset, you will need to choose the variables you want to use in your autoregression model. In our case, we will be using the import and export values of goods between countries as our independent variables.
3) Estimate your model: After choosing your independent variables, you can estimate your autoregression model using the method of least squares. OLS estimation can be done in many statistical software packages such as R or STATA.
4) Interpret your results: Once you have estimated your model, it is important to interpret the results in order to understand what they mean. The coefficients represent the effect that each independent variable has on the dependent variable. In our case, the coefficients represent the effect that imports and exports have on trade balance. A positive coefficient indicates that an increase in the independent variable leads to an increase in the dependent variable while a negative coefficient indicates that an increase in the independent variable leads to a decrease in the dependent variable.
5)Make predictions: Finally, once you have interpreted your results, you can use your autoregression model to make predictions about future values of the dependent variable based on past values of the independent variables.
Conclusion: In this blog post, we have discussed what autoregression is and how to find autoregressive parameters.
Estimating an autoregression model is a relatively simple process that can be done in many statistical software packages such as R or STATA.
In statistics and machine learning, autoregression is a modeling technique used to describe the linear relationship between a dependent variable and one more independent variables. To find the autoregressive parameters, you can use a method known as least squares regression which minimizes the sum of squared residuals. This blog post also explains how to set up your data for calculating least squares regression as well as how to calculate Variance and Covariance before finally calculating your autoregressive parameters. After finding your parameters you can plug them into an autoregressive equation to start making predictions about future events!
We have also discussed three different methods for estimating those parameters: Ordinary Least Squares, Maximum Likelihood, and Least Squares with L1 Regularization. The appropriate estimation method depends on your particular goals and situation.

Autoregressive Model
Autoregressive generative models can estimate complex continuous data distributions such as trajectory rollouts in an RL environment, image intensities, and audio. Traditional techniques discretize continuous data into various bins and approximate the continuous data distribution using categorical distributions over the bins. This approximation is parameter inefficient as it cannot express abrupt changes in density without using a significant number of additional bins. Adaptive Categorical Discretization (ADACAT) is proposed in this paper as a parameterization of 1-D conditionals that is expressive, parameter efficient, and multimodal. A vector of interval widths and masses is used to parameterize the distribution known as ADACAT. Figure 1 showcases the difference between the traditional uniform categorical discretization approach with the proposed ADACAT.
Each component of the ADACAT distribution has non-overlapping support, making it a specific subfamily of mixtures of uniform distributions. ADACAT generalizes uniformly discretized 1-D categorical distributions. The proposed architecture allows for variable bin widths and more closely approximates the modes of two Gaussians mixture than a uniformly discretized categorical, making it highly expressive than the latter. Additionally, a distribution’s support is discretized using quantile-based discretization, which bins data into groups with similar measured data points. ADACAT uses deep autoregressive frameworks to factorize the joint density into numerous 1-D conditional ADACAT distributions in problems with more than one dimension.

- Data scientist in pharma trying to figure out what’s the best path forwardby /u/thro0away12 (Data Science) on July 16, 2026 at 9:06 pm
I’m a data scientist (more like an analytics engineer) in pharma. My background is clinical - I went to school for a healthcare degree and then went into research before coming into data. With that, I have about a decade of experience now doing a little bit of a lot of things - statistics, epidemiology, data/analytics engineering, data visualisation, product management, data governance, etc. Over the course of the last few years, I’ve felt a little stagnant - currently I’m not really doing anything that feels all that important lol, I mean essentially my team was building data pipelines and im redesigning the process for projects that are already ongoing or near completion. The only good thing is I have some downtime which gives me an opportunity to explore different teams and projects. There’s 3 teams I’d like to work with but I can’t work with them all at the same time and have to figure out how best to prioritise each team and allocate time so I can get better exposure Team 1 - a data science team that focuses on a specific disease area, the opportunity would be to continue working in data science while staying close to the business side of our projects by developing a deeper understanding of clinical context. Team 2 - Generative AI engineering - this would be more technical and I probably can’t work with this team right away until I get up to speed with learning concepts like embeddings, chunking, RAGs which I’ve never done before. Team 3 - the downstream users of my data pipelines who apply ML/AI techniques to the data for biomarker discovery Just wanted to hear insights in terms of an industry perspective, which teams would be the best to work on a project with submitted by /u/thro0away12 [link] [comments]
- New Fable5/Opus4.8 harness called "Schema" claims 99% on ARC-3 [R]by /u/we_are_mammals (Machine Learning) on July 16, 2026 at 9:02 pm
Schema, the harness we introduce today, reaches 99% on the ARC‑AGI‑3 Public set using Claude Opus 4.8 and Fable 5, and 95.35% using GPT‑5.6 Sol. It does not change the underlying model weights. Instead, it changes the process around them: how observations are turned into a working model of the game, how predictions are tested against the interaction history, and how plans are executed and revised. Both scores come from a fixed fallback rule: Opus 4.8 and Sol xhigh run first; games scoring below 80 are rerun with Fable 5 and Sol max, respectively, and the higher per-game score is retained. https://schema-harness.github.io/ The president of ARC Prize tweeted this saying "Looks cool - need to dig into it" I'm not affiliated with ARC Prize, or with this team.

- Seeking collaborators for scaling and independent evaluation of a new recurrent language model architecture (preprint + code) [R]by /u/BleedingXiko (Machine Learning) on July 16, 2026 at 7:17 pm
Hi everyone, I've been working independently on a recurrent architecture called **DABSN (Dynamic Adaptive Bias State Network)** for the past several months, and I finally reached the point where I feel comfortable sharing the first preprint. The paper is mainly about the architecture itself and its behavior on reasoning, memory, and long-sequence benchmarks (MQAR, Copy, Key-Value retrieval, A5/60, etc.). The code is also public with PyTorch, C++, and Triton implementations so everything can be reproduced. While finishing the paper, I also trained my first language model with the same cell: - 24M parameters - 1B pretraining tokens - GPT-2 tokenizer Those results ended up being much more interesting than I expected, so I'm now writing a second paper focused entirely on language modeling, long-context behavior, and scaling. This is where I'd love some help. I'm looking for people who might be interested in collaborating on the next paper, whether that's: - independent reproduction of the results, - helping design stronger baselines and evaluations, - or having access to larger GPU clusters so we can scale the architecture much further than I can on my own. Everything I'm doing is intended to be open and reproducible from day one. I'd really appreciate any feedback on the paper, and if the project sounds interesting, I'd love to chat. Preprint and Github are in the comments. submitted by /u/BleedingXiko [link] [comments]
- CfP | RTCA @ NeurIPS 2026 [R]by /u/Few-Ferret9700 (Machine Learning) on July 16, 2026 at 4:51 pm
Call for Papers and Demos Real-Time Conversational Agents (RTCA): Toward Natural Multimodal Interaction 1st RTCA Workshop [@]() NeurIPS 2026, Sydney, Australia 11 or 12 December 2026 Website: https://rtcaneurips26.github.io/ We are pleased to share the Call for Papers and Demos for the inaugural RTCA Workshop at NeurIPS 2026, focused on real-time multimodal conversational agents: streaming speech, video, and language generation; naturalness in interaction; and evaluation of live systems. Conversational AI has moved from text chat into the real world, voice modes that talk back, embodied avatars, agents that share our screens and tools. To feel natural, these systems must operate in real time, streaming while continuously listening, watching, and re-planning. This is fundamentally harder than offline generation: latency, turn-taking, backchannels, interruptions, and cross-modal alignment become first-class problems that the offline paradigm sidesteps. Recent progress on full-duplex speech–language models, real-time talking-head generation, and streaming ASR shows the regime is feasible, but the field still lacks shared benchmarks, vocabulary, and methodology for interactional naturalness. RTCA brings together researchers across speech, vision, language, HCI, social-signal processing, and ML systems around three intertwined questions: real-time generation under hard latency budgets, naturalness in interaction, and evaluation of live systems. Topics of Interest We invite original contributions on topics including (but not limited to): Streaming/low-latency speech synthesis, ASR, and full-duplex audio–language models Real-time talking-head, avatar, and embodied video generation; lip-sync, gaze, expressivity under streaming Streaming language models; incremental and speculative decoding for dialogue Turn-taking, backchanneling, interruption handling, and floor management Multimodal alignment under latency and partial-observation constraints Prosody, emotion, and paralinguistic generation in interactive settings Memory, grounding, and tool use during live conversation Evaluation of naturalness: perceptual studies, turn-taking metrics, perceived latency, interactive Turing-style tests Datasets and benchmarks for interactive (not offline) evaluation Efficient inference, on-device deployment, and the systems–quality trade-off Safety, identity, and trust in real-time agents (deepfakes, persuasion, consent) Submission Types We welcome: Full papers (up to 8 pages) — may be presented as posters and/or contributed talks. Short papers (up to 4 pages) — work in progress or focused contributions. Demo papers (Extended Abstracts or up to 2 pages) All submissions must use the NeurIPS 2026 style file and be formatted for double-blind review. Page limits exclude references and appendices. Papers must be submitted in PDF format via OpenReview (portal link to be published on the workshop website). The workshop is non-archival; authors retain the right to publish elsewhere. Important Dates (End of day, Anywhere on Earth) Call for papers opens: 18 July 2026 Submission deadline (papers and demos): 29 August 2026 Author notification: 29 September 2026 Workshop date: 11 or 12 December 2026 Organisers Niki Foteinopoulou — Tavus, United Kingdom Alessandro Conti — Tavus, Italy Jack Saunders — Tavus, United Kingdom Oya Celiktutan — King's College London, United Kingdom Cigdem Beyan — University of Verona, Italy Ioannis Patras — Queen Mary University of London, United Kingdom For more information, visit our website https://rtcaneurips26.github.io/ or contact us at [rtca-workshop@googlegroups.com](mailto:rtca-workshop@googlegroups.com).

- Companies making you do a full OA before you’ve even talked to a humanby /u/Lamp_Shade_Head (Data Science) on July 16, 2026 at 4:25 pm
Recently I got an automated email from a company I’d applied to, asking me to do a 2 hour online assignment. It didn’t give specifics, just said SQL and Python. When I started it, it turned out to be SQL plus a full end to end model development project. I think I did fine since the problem itself wasn’t too difficult and it’s something I do daily. This was followed by an automated rejection email. So I spent hours prepping and doing an assessment without ever talking to a human. It made me question my own decision to sign up for this. This was a giant corporation, by the way, not a startup or anything. What do you all do in this situation? submitted by /u/Lamp_Shade_Head [link] [comments]

the context is that I am exploring a few recurring problems to solve especially around forecasting and working with time series data but setup a simple open source project around those. my question is primarily about how is everyone handling their official datasets when trying new tools - do you not care, do you remove any identifiers then upload, do you create synthetic data with exactly same properties as the og dataset? happy to answer more questions if this is not clear enough. submitted by /u/shivamchhuneja [link] [comments]
- Are Current AI Memory Architectures Optimizing for the Wrong Abstraction? [D]by /u/Boris_Ljevar (Machine Learning) on July 16, 2026 at 4:00 pm
While writing an essay about AI memory and persistent context, I started wondering whether current AI memory systems are optimized for the right thing. Current AI systems already maintain forms of persistent context through saved memories, conversation summaries, user preferences, project notes, and similar mechanisms. These memories are primarily descriptive. They help the system remember facts about the user and previous interactions. But suppose future systems evolved in a different direction. Instead of primarily storing facts and preferences, imagine the persistent context being continuously refined and restructured to infer higher-level patterns such as recurring explanatory frameworks, preferred abstractions, and characteristic reasoning styles. For example, rather than remembering: "This user is interested in economics." "This user works in engineering." the system might gradually infer: "This user tends to explain economic outcomes through incentives and institutional constraints." "This user tends to understand complex systems through interactions and feedback loops rather than by analyzing individual components in isolation." In such a system, persistent context would become less like a collection of notes and more like an evolving model of how the user understands and interprets problems. Could representations like this emerge naturally from sufficiently capable AI systems, or would they require architectures fundamentally different from today's memory, retrieval, and summarization approaches? submitted by /u/Boris_Ljevar [link] [comments]
- ExTernD: Expanded-Rank Ternary Decomposition Ternary LLM PTQ with Accuracy Approaching Any Quantization Level [P]by /u/LMTLS5 (Machine Learning) on July 16, 2026 at 1:31 pm
https://arxiv.org/pdf/2607.13511 the core idea is, we cannot have ternary PTQ with fixed matrix size, trying to do that is dead end. so i tried decomposing the matrix to 2 ternary matrices and inner diagonal scaling matrix. now that the inner rank can be arbitrarily large the accuracy can be arbiratily small. and its not that it has to be very large too i also showed that it does take only slightly more vram then current quantisation methods. the slight more vram is worth it if we abuse the ternary math. submitted by /u/LMTLS5 [link] [comments]

- The qlora 2e-4 default is wrong under 10k samples and nobody talks about it [D]by /u/Pretty-Ad774 (Machine Learning) on July 16, 2026 at 12:50 pm
Every qlora tutorial on earth says start at 2e-4. Unsloth docs, hf examples, the paper itself. and for small datasets i now think that numbers is a trap. Where does 2e-4 come from? alpaca. 52k samples. cool, except most of us are fine tuning on 5-10k samples we scraped and labeled ourselves, not 52k. at that size the model overfits inside epoch one and then youre just watching training loss go down all pretty while eval lost sits there doing nothing. or climbs. I burned close to three weeks on this. recleaned the data set twice. rewrote the prompt template twice. spent on entire sunday hand relabeling rows while my flatmate watched football next to me (started with 8k rows, ended around 7200 after cutting garbage, i think, didnt log it properly). eval did not move. you you know what’s worse than a bad eval? seven identical bad evals in a row. Then i changed one number. 2e-4 down to 1e-4, epochs 3 to 5. eval jumped more than everything else combined. i sat there refreshing wandb thinking it was a fluke. three more runs, same story. And the annoying part, unsloth literally calls 2e-4 “a starting point” in their own docs. but every shared notebook has it hardcoded, zero comment. so people copy paste, get garbage, blame their data, blame their rank, lose a week. ask me how i know lol. My rule now. above 30k 2e-4 is probably fine. under 10k, start at 1e-4 or lower and add epochs. in between, actually tune it, its one number, takes an afternoon. If there’s real research defending flat 2e-4 on small data i want to read it. and if you all quietly figured this out in 2024 and never posted about it, im mad at every one of you individually. submitted by /u/Pretty-Ad774 [link] [comments]

- Best current tools for Multi-Objective Surrogate-Based Optimization (MOSBO) on heterogeneous study data meta-analysis?[P]by /u/BleakReason (Machine Learning) on July 16, 2026 at 5:43 am
I'm working on a project with summarized data from ~40 studies (Excel) involving different protocol variables (durations, intensities, recovery times, frequency, total duration, etc.) and response outcomes conditional on a baseline variable (range ~30-85 units). The aim is to fit a continuous response surface using a hierarchical approach to separate protocol effects from baseline effects, then perform continuous numerical optimization (not grid search) for three objectives: - Total improvement - Improvement per unit time (e.g. per week) - Improvement per unit effort/work Outputs should be fine-grained continuous values rather than rounded study parameters. There are also domain-specific physiological constraints to respect. I'm on a Chromebook with a little Python experience, so Colab-friendly solutions would be ideal. Current candidates I'm considering: PyMC for hierarchical modeling, pymoo + pysamoo for surrogate-assisted MO optimization, SMT for surrogates, or Matlab Global Optimization Toolbox. What is the strongest stack in 2026 for this kind of workflow? Any recommended notebooks, tutorials, or similar applied examples? Are there any AI tools that currently do this without the traditional work of python? Meaning I can upload the spreadsheet give a parameters and it will come up with data.? submitted by /u/BleakReason [link] [comments]
- I’m not readyby /u/Davidat0r (Data Science) on July 15, 2026 at 8:02 pm
Three years ago I was able to pivot from engineering (no coding) to data science. I’ve been working here at a job I love, with an awesome team & boss and with a great pay. I’m 47, so not the youngest. Now for family reasons I must leave and move back to my country of origin. The thing is that, although I love the field and I keep reading books and trying to learn every day, this is such a vast field that I don’t think I’m ready at all. In these 3 years I’ve done basic ML projects, lots of xgboost, random forests, anomaly detection, dealing with pySpark with PB -sized dataframes, etc. But putting those models to production was made by my more experienced colleagues. So, while I can say I’ve learnt on each project, I also see how MUCH I lack compared with my teammates, with 10+ years exp. on the field. Today I just started looking for DS jobs and I just felt so depressed. Many ask for a DS who can do the whole thing from cleaning data to taking the models to production. I have no idea of that and it sounds extremely intimidating. I also dread the interview because while I can code, I often use LLMs for things that due to the pace of work, I simply decided to do with AI, i.e.: I understand and can read window functions but I’d need an AI to write them because I can never keep the sintaxis in mind. If an interviewer sees me struggling with the syntax, the interview is done I feel very “green” to compete out there with other “proper” data scientists who have a well defined experience and knowledge. I wouldn’t mind applying to junior jobs but due to my age, most companies here wouldn’t hire a 47yr old “junior”. I’m not able to work my old job in the location we’re moving to because it’s very niche and only a certain sector and a certain company size hires for that, and that isn’t there in our new area. I don’t know what to do, or if this is normal and everybody feels like that. Or maybe you guys have any advice… Anything you can come up with will be highly appreciated because I need to provide for two kids and I just don’t know how. I’m beginning to feel desperate submitted by /u/Davidat0r [link] [comments]
- Value to the mentees?by /u/Thin_Original_6765 (Data Science) on July 15, 2026 at 7:55 pm
Those received mentorship, did you find it worth your time in general? In my early career, I actively participated in mentorship program at my alma mater. However, most if not all students wanted to work in tech. Considering I didn't (and still don't) work in tech, and that my employer was rarely hiring, I felt there was not much value I could provide. There's also this self-selection process at play, which is those who seek mentorship tends to already have a good idea of what they should be doing. Now a decade into my career, my expertise is super irrelevant to people in a different industry. I'm also oblivious to the entry-level job market requirements. Recently, my alma mater reached out again for mentors. I've skipped the last few requests but think maybe I should ask y'all before turning it down again. To clarify, I'm not asking if it's worth it for me. I'm wondering if it's worth it for the students to speak with someone unfamiliar with entry-level job market, has expertise in a not niche but definitely not popular domain, and definitely don't lead to job opportunities. Edit: I messed up somewhere that two posts were created. 0_o submitted by /u/Thin_Original_6765 [link] [comments]
- Looking for JEPA devil advocates [R]by /u/Amazing-Coat5160 (Machine Learning) on July 15, 2026 at 5:34 pm
I am currently doing research on world models, specially in tje field of robot learning, and, as probably most of you alredy know, JEPA-like models are mentioned over and over. I read the main recent papers from lecun as well as other research groups, and I personally think the whole approach is very promising and can really go somewhere. But after listening a bunch of the recent Y Lecun conferences his ideas looks even too cool compared to "literally everything else" (as he's dissing LLM, RL, etc and pitching his ideas are the "only next big things"...). So I am asking myself if there are red flags about his approaches that I do not see yet and maybe I need somebody being the "devil advocate" with whom breaking down ideas. Where do you think are the biggest downside of this models, compared to other world models approaches? submitted by /u/Amazing-Coat5160 [link] [comments]

- All major robotics and VLA papers, ranked and benchmarked in a single place [P]by /u/NielsRogge (Machine Learning) on July 15, 2026 at 4:05 pm
Hi folks, There is now a dedicated Robotics page on Papers with Code that lists the major benchmarks, trending papers with linked code, and open-source artifacts. Find it here: https://paperswithcode.co/tasks/robotics https://preview.redd.it/wvhcgu1q1fdh1.png?width=3034&format=png&auto=webp&s=9a43021f7b8e1b840b09f55bb8aee0c4b2d54215 Major benchmarks that most papers report evaluations on are: - LIBERO, as well as its subsets like LIBERO-Long and LIBERO-Spatial - SimplerEnv WidowX - RoboTwin and more. Currently, we have about 110 entries on each benchmark. Each benchmark's progress is visualized over time: https://preview.redd.it/myl3ysvv2fdh1.png?width=2880&format=png&auto=webp&s=3fae2b73d592f2c7ddd3118ec2c5a0d5c5e93b65 We also show which models are open source and which aren't. Let me know which others I missed. I'd be happy to add them. Also happy to hear any feedback, new tasks, or features to add!

- NeurIPS reviews coming in soon! [D]by /u/Practical-Buddy6323 (Machine Learning) on July 15, 2026 at 3:13 pm
So, from what I've seen across twitter(x) and reddit, I've inferred that we'll be seeing NeurIPS reviews drop on July 22nd 5:30 pm AoE(Anywhere on earth), what's your thoughts to those who've submitted to NeurIPS 2026 ? Would love to hear your opinion by the reviewers, the people who've submitted to the workshops (who should've already gotten their decisions too by now I think) and to the main tracks and other available tracks. submitted by /u/Practical-Buddy6323 [link] [comments]
