$pi^{*}_{0.6}$: a VLA That Learns From Experience

arXiv:2511.14759v2 Announce Type: replace Abstract: We study how vision-language-action (VLA) models can improve through real-world deployments via reinforcement learning (RL). We present a general-purpose method, RL with Experience and Corrections via Advantage-conditioned Policies (RECAP), that provides for RL training of…

Energy-based generator matching: A neural sampler for general state space

arXiv:2505.19646v3 Announce Type: replace Abstract: We propose Energy-based generator matching (EGM), a modality-agnostic approach to train generative models from energy functions in the absence of data. Extending the recently proposed generator matching, EGM enables training of arbitrary continuous-time Markov processes,…

It’s LIT! Reliability-Optimized LLMs with Inspectable Tools

arXiv:2511.14903v1 Announce Type: new Abstract: Large language models (LLMs) have exhibited remarkable capabilities across various domains. The ability to call external tools further expands their capability to handle real-world tasks. However, LLMs often follow an opaque reasoning process, which limits…

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…
