arXiv:2603.28324v1 Announce Type: new Abstract: We introduce a novel conditional stochastic interpolant framework for generative modeling of three-dimensional shapes. The method builds on a recent LDDMM-based registration approach to learn the conditional drift between geometries. By leveraging the resulting pull-back and push-forward operators, we extend this formulation beyond standard Cartesian grids to complex shapes and random variables defined on distinct domains. We present an application in the context of cardiovascular simulations, where aortic shapes are generated from an […]

arXiv:2604.01606v1 Announce Type: new Abstract: Optimization over the space of probability measures endowed with the Wasserstein-2 geometry is central to modern machine learning and mean-field modeling. However, traditional methods relying on full Wasserstein gradients often suffer from high computational overhead in high-dimensional or ill-conditioned settings. We propose a randomized coordinate descent framework specifically designed for the Wasserstein manifold, introducing both Random Wasserstein Coordinate Descent (RWCD) and Random Wasserstein Coordinate Proximal{-Gradient} (RWCP) for composite objectives. By exploiting coordinate-wise structures, […]

arXiv:2604.01310v1 Announce Type: new Abstract: Large vision-language models (VLMs) excel on general benchmarks but often lack robustness in medical imaging, where heterogeneous supervision induces cross-dataset interference and sensitivity to data regime (i.e., how the supervisory signals are mixed). In realistic clinical workflows, data and tasks arrive sequentially, so naive continual training further leads to catastrophic forgetting. To address these challenges, we propose MedQwen, a parameter-efficient medical VLM that couples a spectrally routed Mixture-of-Experts (MoE) with a theoretically grounded […]

I originally got asked to write about app/azure_integrations/azure_maps.py—specifically the cache key scheme (tile vs geohash), TTL heuristics by zoom level, and the fallthrough behavior to the upstream geocoder with backoff. That’s exactly the post I wanted to write, because that file is real and non-trivial in this codebase: it defines an Azure Maps client (async, httpx-backed), exposes geocoding methods (including geocode_address referenced from our LangGraph manager), and it’s wired into the enrichment graph as the “last mile” location […]

Modern microscopy routinely produces gigapixel images that contain structures across multiple spatial scales, from fine cellular morphology to broader tissue organization. Many analysis tasks require combining these scales, yet most vision models operate at a single resolution or derive multi-scale features from one view, limiting their ability to exploit the inherently multi-resolution nature of microscopy data. We introduce MuViT, a transformer architecture built to fuse true multi-resolution observations from the same underlying image. MuViT embeds all patches into […]

arXiv:2603.12341v1 Announce Type: new Abstract: Social media can reveal patient experiences with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) that extend beyond clinical trial data. We analyzed 410,198 Reddit posts (May 2019-June 2025) mentioning semaglutide or tirzepatide. A total of 67,008 users self-reported using these medications, and 43.5% described at least one side effect. Gastrointestinal symptoms predominated, including nausea (36.9%), fatigue (16.7%), vomiting (16.3%), constipation (15.3%), and diarrhea (12.6%). Notably, reproductive symptoms (e.g., menstrual irregularities) and temperature-related complaints (e.g., […]

A typical software engineer deals daily with threads, processes, synchronization, race conditions, context sharing etc. A typical frontend engineer does not, but to build modern scalable interactive apps, one should. Why do multi threaded rendering ? The DOM is single threaded (still is, and might be forever). But we want to do more with it. Here are some cases where a single thread starts becoming a bottleneck: Heavy data visualizations, dashboards with multiple visualizations Apps with complex and […]

arXiv:2602.02521v1 Announce Type: new Abstract: Scaled dot-product attention (SDPA) is a fundamental component responsible for the success of large-language models and other nonlinear signal processing applications. The rationale for SDPA has been based upon “query, key, value” concepts borrowed from database theory, but these concepts are difficult to reconcile with standard methods in mathematical signal processing. We show that SDPA can be rewritten in a different but mathematically equivalent form as a projection of the input vectors onto […]
