Follow-up to my earlier post on learning rules vs. human fMRI. Same five conditions (BP, FA, PC, STDP, untrained), same model weights, now evaluated against macaque V1/V2 (FreemanZiemba2013, single-unit) and macaque V4/IT (MajajHong2015, multi-electrode). Main findings: Early visual alignment is qualitatively conserved across species. STDP (ρ ≈ 0.30) and PC (ρ ≈ 0.28) lead at macaque V1/V2, consistent with their position in human V1. The pattern isn't an fMRI artifact. The untrained baseline result doesn't replicate cleanly. In human fMRI, Random ≥ BP at V1. In macaque, STDP and PC pull ahead of Random (electrophysiology has enough SNR to resolve the difference fMRI can't). IT alignment scales with capacity, not learning rule. ResNet-50 (pretrained, ImageNet): ρ ≈ 0.25 at macaque IT. Custom 3-conv CNN across all learning rules: ρ = 0.07–0.14. The IT convergence from the companion paper looks like a capacity floor. Cross-species IT rankings: Kendall's τ = 0.00 (p = 1.00) but n = 5 only has power at τ = ±1.0, so this is uninformative rather than evidence of non-conservation. Limitations worth noting: V1/V2 and V4/IT come from different macaque datasets with different stimulus sets (textures vs. objects): the V2→V4 drop is confounded by this switch Stimulus control shows IT rankings are weakly inverted across stimulus sets (τ = −0.40), so cross-species IT differences may be partially stimulus-driven Companion paper: arxiv.org/abs/2604.16875 Cross-species paper: https://arxiv.org/abs/2605.22401 Code: github.com/nilsleut/cross-species-rsa Happy to discuss the stimulus confound issue or the capacity control in more detail. submitted by /u/ConfusionSpiritual19 [link] [留言]

Profiling PyTorch training has an interesting measurement problem: the more you measure, the more you can change the behavior of the run itself. A simple example is torch.cuda.synchronize() . It gives cleaner timing boundaries, but it also inserts synchronization points into an otherwise asynchronous CUDA workload. An alternative is to use CUDA events around selected boundaries and read them later, so timing can be captured without forcing synchronization in the hot path. This does not replace PyTorch Profiler or Nsight, but it can work as a lightweight first pass before deeper operator-level profiling. I wrote a short technical note about this while working on an open-source PyTorch training diagnostics tool: https://medium.com/p/19adf1054bcf submitted by /u/traceml-ai [link] [留言]

Hi everyone, I'm finishing up my proposal for my undergraduate thesis for computer science on sign language recognition, specifically Filipino Sign Language and i want to ask what architecture to use for my methodology that is best, rn im considering Mediapipe Holistic + Transformers or Media Pipe Holistic + Mamba SSM. The only caveat is prev researches already done the first one and im not very familiar with the latter. Which do you think is the best method? Thank you submitted by /u/Unable_Let_6998 [link] [留言]

We're writing a research paper on explainable fraud detection GNN model and in the first step we're creating a basic Graph Neural Network for that. We're using the most famous dataset available on this topic i.e IEEE CIS Fraud Detection Dataset and implemented all necessary feature engineering on that data (although majority of feature engineering is already performed in the dataset). Then we constructed a heterogeneous graph on that dataset. Various transaction features like device, transaction id, amount are embedded as nodes and connected with transaction nodes. But the issue is after training the model isn't performing well. It is producing average AUC of 0.87, PR-AUC of 0.52, recall@5% around 0.57 and precision@5% around 0.37 (We tried GCN, GraphSAGE and GAT, all performs almost same for rest data) Whereas the SOTA models in this topic produce much better metrics. Can anyone tell where potentially we're doing things wrong? submitted by /u/LiveAccident5312 [link] [留言]

I randomly came across this conference/workshop: IEEE Workshop on Machine Learning for Signal Processing. Is this a reputable conference and is it worthwhile to submit here vs. a workshop at an A* like ICML, NeurIPS, etc.?(I know these deadlines have passed, I have a paper currently under review.) I know IEEE varies considerably in quality. I'm an undergrad at a smaller liberal arts school so I unfortunately have limited advising on good quality places to submit, and I don't think this current research project is quite top conference-level. submitted by /u/B3anman [link] [留言]

Paper: https://arxiv.org/abs/2605.08172 Workshops: AI for Science & Structured Data for Health at ICML 2026 Abstract: Anatomical mesh segmentation requires models that operate directly on irregular surface geometry while remaining robust to arbitrary patient pose and mesh resolution variation. Existing task-specific mesh and point-cloud methods are not equivariant, and can degrade sharply under test-time perturbation, for example dropping by 25-26 IoU points on intraoral scan segmentation at 40 o tilt. We present EAMS, an Equivariant Anatomical Mesh Segmentor built on Equivariant Mesh Neural Networks (EMNN), and evaluate it across four clinically distinct tasks spanning edge-, vertex-, and face-level supervision. We combine intrinsic mesh descriptors with anatomy-aware priors, including PCA-derived frames for dental arches and liver surfaces, and augment message passing to provide lightweight global context. Across intracranial aneurysm and intraoral segmentation, EAMS variants are competitive with specialized baselines on unperturbed inputs while remaining stable under geometric perturbations, and on liver surfaces they expose a favorable trade-off between canonical-pose accuracy and rotation robustness. These results show that a lightweight (<2M parameters) equivariant framework can deliver robust anatomical mesh segmentation across diverse supervision types without task-specific architectures. Hi everyone I’m excited to share my solo paper "Augmented Equivariant Mesh Networks for Anatomical Mesh Segmentation" which has been accepted for poster presentations at the ICML 2026 workshops on AI for Science and Structured Data for Health . The project stemmed from my parallel research on structural encoders for biomolecules where enforcing roto-translational equivariance is standard. In this work, I wanted to extend those principles directly to various 3D medical meshes. While current anatomical mesh segmentation methods are highly disjoint and anatomy-specific, we pre

I’ve been reading GPU architecture docs in my free time. NVIDIA PTX, AMD ISA reference guides, Intel Xe, reverse-engineered Apple GPU stuff. Over 5,000 pages across 16 microarchitectures. After a while you notice all four vendors are doing the same 11 things with different names. So I wrote a spec that covers all of them and built a toolchain around it. It’s called WAVE. You write a kernel once, it compiles to a portable binary, then thin backends translate it to Metal, PTX, HIP, or SYCL. Same binary verified on Apple M4 Pro, NVIDIA T4, and AMD MI300X. My co-author Onyinye built PyTorch integration and got identical training results across all backends.

Looking for communities where people actually dig into ML/AI research, not hype, not "look what I built with an LLM API," but discussions about papers, training dynamics, debugging real models, infra problems, that kind of thing. I'm specifically interested in places where you can post something like "I'm seeing X behaviour in my SSL training, here's the loss curve, anyone seen this before?" and get thoughtful replies instead of generic advice. submitted by /u/Possible-Active-1903 [link] [留言]

Nathan Witkin, a research writer at NYU Stern’s Tech and Society Lab, writes damningly about the famous METR AI time horizons graph in the Substack publication Transformer: It is impossible to draw meaningful conclusions from METR’s Long Tasks benchmark — in particular once one realizes that its numerous flaws are probably compounding in unpredictable ways. The appropriate response to a study of this kind is not to assume it can be saved via back-of-the-envelope adjustments, or to comfort oneself that other anecdotal evidence implies that it is probably correct anyway. It is to cut one’s losses and move on in search of higher-quality information. … The METR graph cannot be saved. For all its sleekness and complexity, it contains far too many compounding errors to excuse. Among them is generalizing to the entire species data collected from a small group of the authors’ peers. Coming up with ever more dramatic ways to make this mistake has become a kind of sport among AI researchers. If the field has a central pathology, it is to aggressively overindex on a mix of anecdotal data from power-users, alongside a long list of benchmarks even more compromised than METR’s. One hopes that as the field matures, its participants will learn to stop making these mistakes. The errors include: Some of the human baselines data is not actually measured or collected from any empirical source, rather, it is just guesstimated by the authors A key variable in the data is how long it takes humans to complete certain tasks, but — when METR did actually measure this — it paid its human benchmarkers hourly, meaning they were incentivized with cash to take longer The sample of human benchmarkers was biased toward METR employees’ friends, acquaintances, and former colleagues (who are likely unrepresentative and possibly biased) Humans familiar with a codebase and a specific coding task were 5-18x faster at completing it, but METR used data from humans who were much slower because they had to s

Just thought I'd share, I ran a DCGAN on a dual core RISC-V microcontroller, the CH32H417 generating 64x64 cat faces. This is a new RISC-V MCU, so no TFLite, no CMSIS NN and no external memory. It's a pure C inference engine, bit-identical to PyTorch reference outputs. The model is 12.6M parameters with int8 per channel quantization. Intermediate activations are stored in DTCM and layer weights stream from SD card using double buffering so the next layer loads while the current one computes. The total available SRAM is 512KB shared between both cores and the inference engine and time to generate one image is 26 seconds, it could be faster, but SD card access speed is the bottleneck rather than computation. The z vector is seeded from 200 bytes of quantum random data (ANU QRNG vacuum fluctuation source), transformed via Box-Muller into the latent vector. which is not strictly necessary for image quality but it was a fun constraint for the art installation side of the project. The generated cat is classified as "motivated" or "demotivated" based on a single quantum bit, which selects from a phrase bank with four fragment slots combining into one of 131,072 possible spoken verdicts output through the onboard DAC... As far as I can tell nobody else is running GAN inference on these low cost RISC-V microcontrollers, cause ARM has the CMSIS NN ecosystem for this kind of thing but RISC-V MCUs especially in the CH32 space have nothing, so the entire inference engine is written from scratch.

Hi! I missed securing a main conference ticket for ICML 2026, as my workshop paper got accepted two days ago. Do you believe that it is worth attending just workshops at such A*-tier conferences (with all the overseas travel costs etc.)? I was quite looking forward to attending both, including the talks, poster sessions and company booths. I come from an adjacent field and have therefore had quite a few conference experiences. Any insights into past experience are highly welcome. Thank you! submitted by /u/dreameroutloud [link] [留言]
