• LePlanner: An Iterative Amortized Controller For World Models — LePlanner, an amortized iterative controller for world model-based robot planning, matches search planners (CEM, MPPI) at 98% success on PushT and 100% on Reacher while requiring 3-49x less wall-clock time per decision—bringing fast goal-aware robot control closer to deployment.
• ReWeight: Leveraging Human Data for VLA Post-Training via Demonstration Retrieval and Sample Weighting — ReWeight boosts VLA robot policy performance by selectively incorporating egocentric human demonstrations via optimal transport retrieval and cross-embodiment sample weighting, improving π0.5's real-world success rate to 68.8%—a 28.8 percentage point gain over robot-only training.
• SGWIB:Sliced Gromov-Wasserstein Information Bottleneck for Video Highlight Detection — SGWIB introduces a structure-aware information bottleneck for video highlight detection that preserves temporal relationships between segments using a Sliced Gromov-Monge Gap regularizer, improving Kendall's tau by up to 0.031 over prior single-modal methods on MrHiSum.
• RA-CoA: Training-free Fashion Image Captioning via Retrieval-Augmented Chain-of-Attributes — RA-CoA improves fashion product caption quality by 26.3% on METEOR score without model fine-tuning, using retrieval from a product knowledge base to ground attribute-level reasoning in any frozen VLM—directly applicable to e-commerce catalog automation. Accepted in TMLR, code public.
• Talking to Me or Someone Else? Rethinking Talk-to-Me Detection in Egocentric Videos — A multimodal model combining audio, visual, and speech-semantic cues achieves 75.5% frame-level F1 on online talk-to-me detection in egocentric video — reformulating what was a binary offline task into a richer online prediction over four speaking states.
• AURA: Unified Multimodal Framework for Conversational Music Editing — AURA enables iterative conversation-guided music editing by encoding full dialogue history, optional images, and reference audio into compact concept tokens injected into a frozen 1.9B MusicGen backbone — cutting FAD by 4-5x on out-of-domain audio additions with only 91M trainable parameters.
• A Generative AI Integrated Multimodal Framework for Low-Latency Multi-Camera Person Re-Identification — A cost-aware early-exit cascade for multi-camera person re-identification resolves 60.7% of DukeMTMC and 68.4% of Market-1501 queries using only cheap visual features — avoiding expensive VLM semantic analysis on the majority of queries while maintaining competitive retrieval accuracy.
• Bridging the Modality Gap in Long-Form Clinical Audio: A Comparative Study of Lightweight and Heavyweight End-to-End SOAP Generation — The ASLP team's fully end-to-end system generates structured SOAP clinical notes directly from long doctor-patient audio conversations, consistently outperforming cascaded ASR+LLM baselines at both 3B and 30B parameter scales using a 1.41-million-sample training corpus.
• From Visual Feedback to Textual Reviews: A Multi-Agent Vision-Language Framework for Image-Grounded Review Assistance — A four-role multi-agent vision-language framework generates editable product review drafts from user-uploaded images on Amazon Electronics data, introducing 'image-grounded review assistance' as a new task that requires product understanding and sentiment estimation, not just image captioning.
• TimeThink: Eliciting Compositional Reasoning in Timeseries Large Language Models — TimeThink trains timeseries multimodal LLMs using reinforcement learning with verifiable rewards on synthetically generated compositional question-answer pairs—achieving significant improvements over strong baselines on real-world benchmarks despite training only on synthetic data, including healthcare timeseries.
