Structured Contrastive Learning for Interpretable Latent Representations

arXiv:2511.14920v1 Announce Type: new Abstract: Neural networks exhibit severe brittleness to semantically irrelevant transformations. A mere 75ms electrocardiogram (ECG) phase shift degrades latent cosine similarity from 1.0 to 0.2, while sensor rotations collapse activity recognition performance with inertial measurement units…

Bringing Federated Learning to Space

arXiv:2511.14889v1 Announce Type: new Abstract: As Low Earth Orbit (LEO) satellite constellations rapidly expand to hundreds and thousands of spacecraft, the need for distributed on-board machine learning becomes critical to address downlink bandwidth limitations. Federated learning (FL) offers a promising…

Empowering Multi-Turn Tool-Integrated Reasoning with Group Turn Policy Optimization

arXiv:2511.14846v1 Announce Type: new Abstract: Training Large Language Models (LLMs) for multi-turn Tool-Integrated Reasoning (TIR) – where models iteratively reason, generate code, and verify through execution – remains challenging for existing reinforcement learning (RL) approaches. Current RL methods, exemplified by…

Explaining Time Series Classification Predictions via Causal Attributions

arXiv:2405.15871v2 Announce Type: replace Abstract: Despite the excelling performance of machine learning models, understanding their decisions remains a long-standing goal. Although commonly used attribution methods from explainable AI attempt to address this issue, they typically rely on associational rather than…

Streaming Generation of Co-Speech Gestures via Accelerated Rolling Diffusion

arXiv:2503.10488v3 Announce Type: replace Abstract: Generating co-speech gestures in real time requires both temporal coherence and efficient sampling. We introduce a novel framework for streaming gesture generation that extends Rolling Diffusion models with structured progressive noise scheduling, enabling seamless long-sequence…
