- [D] Are GNNs obsolete because of transformers?by /u/Master_Jello3295 (Machine Learning) on March 22, 2025 at 12:56 am
I’ve always been interested in Graph Neural Networks (GNNs) but haven’t had the chance to study them deeply. Now that transformers are prevalent, the attention mechanism—where each query interacts with all keys—feels conceptually similar to operations on densely connected graphs. This makes me wonder if transformers can be considered a type of GNN. Is there any truth to this? Can transformers actually replace GNNs? submitted by /u/Master_Jello3295 [link] [comments]
- [D] Best Practices for Diagramming ML System Internals?by /u/amirdol7 (Machine Learning) on March 21, 2025 at 5:07 pm
Well, in today's world we have so many systems that use ML under the hood. Usually what happens before the development of these systems is that engineers use a diagramming language (i.e, UML for SW) to design the architecture and the working internals. But I find it hard to apply this to ML systems because they involve many different components like pipelines, software pieces, APIs, databases, scheduled task, and more. So my question is: what is the standardized way to diagram these systems? Can UML be adapted for this, or are there better frameworks/resources for diagramming ML system internals? I'm looking for best practices and learning materials. submitted by /u/amirdol7 [link] [comments]

- [R] Scale-wise Distillation of Diffusion Modelsby /u/_puhsu (Machine Learning) on March 21, 2025 at 3:25 pm
Today, our team at Yandex Research has published a new paper, here is the gist from the authors (who are less active here than myself 🫣): TL;DR: We’ve distilled SD3.5 Large/Medium into fast few-step generators, which are as quick as two-step sampling and outperform other distillation methods within the same compute budget. Distilling text-to-image diffusion models (DMs) is a hot topic for speeding them up, cutting steps down to ~4. But getting to 1-2 steps is still tough for the SoTA text-to-image DMs out there. So, there’s room to push the limits further by exploring other degrees of freedom. One of such degrees is spatial resolution at which DMs operate on intermediate diffusion steps. This paper takes inspiration from the recent insight that DMs approximate spectral autoregression and suggests that DMs don’t need to work at high resolutions for high noise levels. The intuition is simple: noise vanishes high frequences —> we don't need to waste compute by modeling them at early diffusion steps. The proposed method, SwD, combines this idea with SoTA diffusion distillation approaches for few-step sampling and produces images by gradually upscaling them at each diffusion step. Importantly, all within a single model — no cascading required. Images generated with SwD distilled SD3.5 Paper Code HF Demo submitted by /u/_puhsu [link] [comments]
- [R] Looking for an Estimator to Measure the Coverage of Sampled Points in N-Dimensional Spaceby /u/Euphoric-Ad1837 (Machine Learning) on March 21, 2025 at 12:29 pm
Let’s say I have a black-box function that maps inputs to points in an N-dimensional space. The function’s output space may be finite or infinite. Given a set of sampled points obtained from different inputs, I want to estimate how much of the function’s possible output space is covered by my samples. For a simpler case, assume the function returns a single numerical value instead of a vector. By analyzing the range of observed values, I can estimate an interval that likely contains future outputs. If a newly sampled point falls outside this range, my confidence in the estimated range should decrease; if it falls within the range, my confidence should increase. What kind of estimator am I looking for? I appreciate any insights! submitted by /u/Euphoric-Ad1837 [link] [comments]
- [D] The Recurrent Delusion: How ML Collectively Forgot What RNNs Were Built Forby /u/JirkaKlimes (Machine Learning) on March 21, 2025 at 12:24 pm
When our field first developed RNNs, they were the obvious choice for sequential tasks until vanishing/exploding gradients and the inherently unparallelizable backpropagation through time (BPTT) limited their scalability. Years of collective research addressing these issues ultimately birthed the Transformer—massively parallelizable, scalable, and easier to train, marking the revolutionary arrival of the golden age of attention. The Ignored Alternatives State Space Models and parallelizable LSTM variants emerged as potential solutions to the parallelization issues of traditional RNNs, but they sacrificed the ability to generalize to problems in the NC1 complexity class which vanilla RNNs can do, staying within TC0 like Transformers. This isn’t just theoretical—after over 3 years and billions spent optimizing hardware for transformers, these alternatives offered virtually no compelling advantage. The Chain of Thought Contradiction Fast forward to Chain of Thought prompting – suddenly we're training models with elaborate reasoning examples, often including this bizarre theatrical process where LLMs are deliberately trained to make mistakes just to demonstrate correction capabilities. It's computational theater. But DeepSeek's R1 approach is where this paradox becomes undeniable. They're using reinforcement learning to train reasoning chains, which is genuinely innovative, but... Why are we still using Transformers for what is fundamentally a recurrent reasoning process? Let me dissect this architectural mismatch: We're tokenizing chains of thought, severely restricting their expressive potential The reasoning process itself functions as a hidden state WITHOUT ground truth labels (which is actually perfect – otherwise we'd just be training glorified memorization) This scenario logically demands a BPTT-like approach – which would be completely unparallelizable even with Transformers since we lack intermediate labels – yet we're circumventing this entire problem with GRPO and somehow getting spectacular results We're essentially performing recurrent optimization while stubbornly avoiding recurrent architectures. The intellectual contradiction is mind-boggling! It's as if the entire field developed collective amnesia about the fundamental principles of sequential processing that motivated RNNs in the first place. The Billion-Dollar Blindspot Let's cut to the chase: RNNs can solve problems in the NC1 complexity class that Transformers fundamentally cannot. This isn't academic nitpicking—it's about computational expressiveness that directly impacts reasoning capabilities. A Transformer forced to use input sequences as pseudo-RNN states is crippled for reasoning: poor length generalization, inefficient information pruning, and suboptimal cache performance. Yet R1's approach—using reinforcement learning without BPTT—works brilliantly and could resurrect even basic RNNs with superior results. At inference, the process is identical: store state, sample outputs, track probabilities, then adjust based on reasoning quality. So why aren't we applying this to architectures designed for sequential reasoning? This architectural mismatch seems strikingly obvious yet remains unaddressed. Is it infrastructure lock-in? Publication pressure? Or has the field collectively forgotten why recurrent networks were created in the first place? The emperor has no clothes. The question is: who will be the first to point it out? submitted by /u/JirkaKlimes [link] [comments]
- [R] TULIP: Enhancing Vision-Language Models with Multi-Modal Contrastive Learning and Generative Regularizationby /u/Successful-Western27 (Machine Learning) on March 21, 2025 at 11:54 am
I've been diving into TULIP, a new approach for vision-language pretraining that addresses what the authors call the "seeing half a scene" problem in models like CLIP. The key insight is combining contrastive learning with masked feature prediction in a unified framework. Technical approach: * Uses a dual-encoder architecture (ViT + text transformer) similar to CLIP * Introduces "block-wise masking with patch shuffling" - a new visual masking strategy * Combines two training objectives: contrastive learning and masked feature prediction * Leverages both real image-text pairs and synthetic data from diffusion models Key results: * State-of-the-art performance across multiple benchmarks: * 70.8% on ImageNet-1K classification (ViT-B) * 77.6% box AP on COCO detection * 58.3% mIoU on ADE20K segmentation * Shows that neither contrastive learning nor masked prediction alone is sufficient * Works well even with limited text descriptions (10M image-text pairs) * Performance scales effectively with increased model size and pretraining data I think this approach represents an important shift in how we build vision-language models. By forcing models to understand both global image-text relationships and local visual feature relationships, we can create systems with more comprehensive visual understanding. The use of synthetic data to supplement real datasets is also pragmatic - it helps address data scarcity for specific concepts without requiring expensive annotation. The block-wise masking strategy seems particularly clever. Instead of randomly masking individual patches (which can be too easy for models to solve), this approach creates a more challenging pretraining task that encourages understanding of spatial relationships. TLDR: TULIP combines contrastive learning with masked feature prediction to create vision-language models that understand both whole images and their detailed components. It achieves SOTA results across multiple vision tasks and demonstrates effective use of synthetic training data. Full summary is here.

- [P] AlphaZero applied to Tetris (incl. other MCTS policies)by /u/Npoes (Machine Learning) on March 21, 2025 at 11:52 am
Most implementations of Reinforcement Learning applied to Tetris have been based on hand-crafted feature vectors and reduction of the action space (action-grouping), while training agents on the full observation- and action-space has failed. I created a project to learn to play Tetris from raw observations, with the full action space, as a human player would without the previously mentioned assumptions. It is configurable to use any tree policy for the Monte-Carlo Tree Search, like Thompson Sampling, UCB, or other custom policies for experimentation beyond PUCT. The training script is designed in an on-policy & sequential way and an agent can be trained using a CPU or GPU on a single machine. Have a look and play around with it, it's a great way to learn about MCTS! https://github.com/Max-We/alphazero-tetris submitted by /u/Npoes [link] [comments]

- [R] Revisiting Semi-Supervised Learning in the Era of Foundation Modelsby /u/oncecookedpork (Machine Learning) on March 20, 2025 at 9:57 pm
Semi-supervised learning (SSL) leverages abundant unlabeled data alongside limited labeled data to enhance learning. As vision foundation models (VFMs) increasingly serve as the backbone of vision applications, it remains unclear how SSL interacts with these pre-trained models. To address this gap, we develop new SSL benchmark datasets where frozen VFMs underperform and systematically evaluate representative SSL methods. We make a surprising observation: parameter-efficient fine-tuning (PEFT) using only labeled data often matches SSL performance, even without leveraging unlabeled data. This motivates us to revisit self-training, a conceptually simple SSL baseline, where we use the supervised PEFT model to pseudo-label unlabeled data for further training. To overcome the notorious issue of noisy pseudo-labels, we propose ensembling multiple PEFT approaches and VFM backbones to produce more robust pseudo-labels. Empirical results validate the effectiveness of this simple yet powerful approach, providing actionable insights into SSL with VFMs and paving the way for more scalable and practical semi-supervised learning in the era of foundation models.

- [R] Analyzing Failure Modes in Sliding Window-Based Time Series Clusteringby /u/Successful-Western27 (Machine Learning) on March 20, 2025 at 11:28 am
This paper explores the mathematical properties of sliding window clustering, proving several fundamental behaviors that explain why certain clustering approaches succeed or fail. The key technical contribution is a set of mathematical proofs showing that the clustering behavior of sliding windows depends critically on window size and data symmetry properties: Small windows produce flat centroids: They mathematically prove that as window size becomes small relative to signal frequency, cluster centroids approach constant functions Near-symmetric data creates meaningless clusters: When data satisfies f(t) ≈ f(-t), they show clustering becomes essentially random Large windows naturally form interval clusters: They prove that optimal clustering of large sliding windows forms intervals (contiguous chunks of the time series) Formal mathematical framework: The paper establishes theoretical foundations using properties of autocorrelation and similarity measures The main results include: Theorem 1 shows that small windows produce nearly identical, flat cluster centroids Proposition 2 demonstrates that with symmetric periodic signals, windows are assigned to clusters essentially randomly Theorem 3 establishes that with large windows, optimal clusters form intervals Several corollaries extend these results to specific clustering algorithms and data types I think this work explains phenomena many practitioners have observed empirically but couldn't fully explain. When working with sliding windows, I've often noticed that small windows produce uninformative clusters while larger ones tend to identify meaningful temporal segments. Now we have mathematical explanations for why this happens. I think these results could guide better algorithm design for time series analysis. Understanding the mathematical limitations of different window sizes should help researchers avoid approaches that are doomed to fail due to fundamental constraints rather than implementation issues. TLDR: The paper provides mathematical proofs showing that small sliding windows produce flat, meaningless clusters; nearly symmetric data makes clustering ineffective; and large windows naturally form interval-based clusters - explaining why some sliding window clustering approaches work while others fail.

- 🤖📈 Can AI Really Predict the Markets? I Put It to the Test. [P]by /u/henryzhangpku (Machine Learning) on March 20, 2025 at 7:37 am
The finance/AI world is split: Do LLMs have predictive power in trading? Some argue markets are too efficient, too noisy for AI to extract real edge. Others believe AI can uncover hidden patterns beyond human capability. Instead of debating, I built an AI-driven Options Trader to find out. 🔬 The Experiment I designed an algorithm that feeds all major LLMs with every possible data point—spanning technical indicators, news sentiment, options flow, macro signals, and cross-market correlations. Instead of cherry-picking signals, AI conducts a comprehensive cross-analysis across models. The rule is simple: ✅ If all LLMs align on a high-probability trade, we take it. ❌ If uncertainty is high or risk/reward is poor, we sit out. This isn't just another AI trading bot. It's an attempt to quantify AI’s true decision-making power in financial markets—something few have rigorously tested. 🤔 What’s the Edge? AI isn’t distracted by market noise—it operates purely on structured analysis. Instead of relying on one AI model, we use an ensemble approach for robustness. The absence of a trade is as valuable as taking one—avoiding unnecessary risk. 🔍 Research & Real-World Testing I’ll be sharing the results, insights, and unexpected findings in my QuantSignals newsletter. If you're curious about AI x Quant Trading and whether LLMs can truly generate alpha in options trading, sign up and follow this journey. 📩 Follow along here: https://open.substack.com/pub/henryzhang/p/nvda-weekly-combo-analysis-2025-03?r=14jbl6&utm_campaign=post&utm_medium=web&showWelcomeOnShare=false What do you think?

- [D] Improving Large-Context LLM calls with filter LLMsby /u/SlackEight (Machine Learning) on March 20, 2025 at 6:31 am
I am working on a system that initially used RAG to fetch relevant information, but recently I found better performance using a CAG/Large-context LLM architecture where I do the following: Pull all the relevant data Use Gemini 2 Flash to take the query + the retrieved data and filter it to only the relevant data Pass the filtered data to the most performant LLM for the task to respond to the prompt. The second step helps mitigate what I’ve seen referred to as the “lost in the middle” phenomenon, and distraction. In my case scaling over time is not a major concern as the context window size stays more or less consistent. The problem, and in hindsight it’s quite obvious, is that even after being filtering, the document is still big — and for the filter LLM to output that filtered document takes up to 20s for Gemini 2 flash. That latency isn’t acceptable in the system. I have considered solutions like enumerating all the data in the context window and getting the filter LLM to only output the indices of relevant data, effectively letting us do lossless compression on the output prompt, meaning we can generate the output faster. In my testing (and I’m not sure if this is really an issue) I’ve found that this produces different results for the filter, which concerns me a bit. So I am still a bit stuck on how best to speed up the filter. I’m curious if anyone else here has tried an architecture like this with filtering large context with an LLM/is knowledgeable enough to weigh in? submitted by /u/SlackEight [link] [comments]

- [D] ICCV 2025 Desk Reject for Appendix in Main Paper – Anyone Else?by /u/hellomellow1 (Machine Learning) on March 19, 2025 at 5:38 pm
Hey everyone, Our ICCV 2025 paper just got desk-rejected because we included the supplementary material as an appendix in the main PDF, which allegedly put us over the page limit. Given that this year, ICCV required both the main paper and supplementary material to be submitted on the same date, we inferred (apparently incorrectly) that they were meant to be in the same document. For context, in other major conferences like NeurIPS and ACL, where the supplementary deadline is the same as the main paper, it’s completely standard to include an appendix within the main PDF. So this desk rejection feels pretty unfair. Did anyone else make the same mistake? Were your papers also desk-rejected? Curious to hear how widespread this issue is. submitted by /u/hellomellow1 [link] [comments]

- [R] Evaluating Video Models on Impossible Scenarios: A Benchmark for Generation and Understanding of Counterfactual Videosby /u/Successful-Western27 (Machine Learning) on March 19, 2025 at 11:58 am
IPV-Bench: Evaluating Video Generation Models with Physically Impossible Scenarios Researchers have created a new benchmark called IPV-Bench to evaluate how well video generation models understand basic physics and logic. This benchmark contains 1,000 carefully crafted prompts that test models on their ability to handle physically impossible scenarios across 9 categories including gravity violations, object permanence issues, and logical contradictions. The key methodology included: - Testing models with both "create impossible" prompts (asking for impossibilities) and "avoid impossible" prompts (requesting physically plausible videos) - Evaluating videos through both automated metrics and human assessment - Testing across multiple state-of-the-art models including Sora, Morph-E, WALT, Show-1, Gen-2, Runway, Pika, and LaVie - Developing a detailed taxonomy of impossible physics scenarios Main findings: - Current SOTA models produce physically impossible content 20-40% of the time even when explicitly asked to follow physics laws - Performance was worst on "change impossibilities" and "contact impossibilities" (~50% accuracy) - Different models show different "impossibility profiles" - making distinct types of physical reasoning errors - Strong text understanding doesn't guarantee strong physical reasoning - Human evaluators easily identified these impossibilities, highlighting the gap between AI and human understanding I think this research reveals a fundamental limitation in current video generation systems - they lack the intuitive physics understanding that humans develop naturally. This matters significantly for applications where physical plausibility is important, like simulation, education, or training robotics systems. The benchmark provides a systematic way to measure progress in this area, which will be crucial as these models become more widely deployed. The taxonomy they've developed is particularly useful as it gives us a framework for thinking about different types of physical reasoning failures. I suspect we'll see this benchmark become an important tool for improving the next generation of video models. TLDR: IPV-Bench is a new benchmark testing video models' understanding of physical impossibilities. Current models frequently generate physically impossible content even when instructed not to, showing they lack true understanding of how the physical world works. Full summary is here. Paper here. submitted by /u/Successful-Western27 [link] [comments]

- [R] RWKV-7 "Goose" with Expressive Dynamic State Evolutionby /u/Wooden-Deer-1276 (Machine Learning) on March 19, 2025 at 3:08 am
RWKV-7 "Goose" with Expressive Dynamic State Evolution Bo Peng, Ruichong Zhang, Daniel Goldstein, Eric Alcaide, Haowen Hou, Janna Lu, William Merrill, Guangyu Song, Kaifeng Tan, Saiteja Utpala, Nathan Wilce, Johan S. Wind, Tianyi Wu, Daniel Wuttke, Christian Zhou-Zheng arXiv:2503.14456 [cs.CL]: https://arxiv.org/abs/2503.14456 Abstract: We present RWKV-7 "Goose", a new sequence modeling architecture, along with pre-trained language models that establish a new state-of-the-art in downstream performance at the 3 billion parameter scale on multilingual tasks, and match current SoTA English language performance despite being trained on dramatically fewer tokens than other top 3B models. Nevertheless, RWKV-7 models require only constant memory usage and constant inference time per token. RWKV-7 introduces a newly generalized formulation of the delta rule with vector-valued gating and in-context learning rates, as well as a relaxed value replacement rule. We show that RWKV-7 can perform state tracking and recognize all regular languages, while retaining parallelizability of training. This exceeds the capabilities of Transformers under standard complexity conjectures, which are limited to 𝖳𝖢0. To demonstrate RWKV-7's language modeling capability, we also present an extended open source 3.1 trillion token multilingual corpus, and train four RWKV-7 models ranging from 0.19 billion to 2.9 billion parameters on this dataset. To foster openness, reproduction, and adoption, we release our models and dataset component listing at this https URL, and our training and inference code at this https URL all under the Apache 2.0 License.

- [R] Forget Chain-of-Thought reasoning! Introducing Chain-of-Draft: Thinking Faster (and Cheaper) by Writing Less.by /u/DanielD2724 (Machine Learning) on March 18, 2025 at 8:58 pm
I recently stumbled upon a paper by Zoom Communications (Yes, the Zoom we all used during the 2020 thing...) They propose a very simple way to make a model reason, but this time they make it much cheaper and faster than what CoT currently allows us. Here is an example of what they changed in the prompt that they give to the model: https://preview.redd.it/p4m5adbqgipe1.png?width=509&format=png&auto=webp&s=32da487a2d054c829609410bd82c4c566dedc405 Here is how a regular CoT model would answer: CoT reasoning Here is how the new Chain-of-Draft model answers: Chain-of-Draft reasoning We can see that the answer is much shorter thus having fewer tokens and requiring less computing to generate. I checked it myself with GPT4o, and CoD actually much much better and faster than CoT Here is a link to the paper: https://arxiv.org/abs/2502.18600 submitted by /u/DanielD2724 [link] [comments]
