RAIN: Robotic Task Generalization with Region-Aware Interaction Networks

Existing vision-language-action (VLA) models benefit from large-scale vision-language pretraining, but tend to memorize training trajectories, limiting their ability to adapt learned interactions to new task and scene configurations. To address this problem, we propose \textbf{Region-Aware Interaction Networks (RAIN)},...

CANTABILE: Learning Expressive Dynamics for Robotic Piano Performance

Robotic piano playing has emerged as a standard benchmark for dexterous bimanual manipulation, yet progress on it has been measured almost entirely by note accuracy -- which keys are pressed (pitch) and when (onset) -- leaving the musical dynamics essential for expressive performance neither rewarded nor evaluated. We...

Object-Centric LiDAR-to-Radar Distillation for 3D Object Detection

Radar is an essential sensor for autonomous driving due to its cost-effectiveness and robustness under adverse weather conditions. However, 3D radar points are inherently sparse, noisy, and lack elevation information. As a result, they provide much weaker geometric cues than LiDAR measurements, making reliable represen...

Learning to Forget: Emotional Salience as a Compression Mechanism for Long-Term AI Memory

The Affective Memory Architecture is introduced, drawing from the amygdala's role in memory modulation to equip AI agents with the essential capacity to actively forget, fundamentally shifting the goal of AI memory from total recall to meaningful retention.

CRAFT: Constrained Reward via Attention Fine-Tuning for Subject Personalization without Composed Targets

Subject-driven image personalization---generating new images that preserve the identity of one or several reference subjects in novel scenes---is a foundational capability for modern visual content creation. It is currently dominated by generalized methods that fine-tune a pretrained multimodal diffusion transformer (M...

Mitigating Noisy Correspondence in Video–Text Retrieval via Noise-Mined Adaptive Self-Labeling

Noise-mined Adaptive Self-Labeling (NASL), which effectively manages noisy data during training and improves the separation between clean and noisy data while effectively mitigating noise, leading to significant performance improvements on the MSR-VTT, DiDeMo, MSVD, LSMDC, and ActivityNet datasets.

Learning to Forget: Emotional Salience as a Compression Mechanism for Long-Term AI Memory

Recent advancements in Large Language Model (LLM) agents have largely focused on extending context windows or implementing massive Retrieval-Augmented Generation (RAG) systems to retain long-term history. However, this store-everything approach causes high computational costs and digital hoarding, paradoxically leading...
