Cast a Wider Net: Coordinated Pass@K Policy Optimization for Code Reasoning
Yilong Li, Suman Banerjee, Tong Che
Repeated sampling with a verifier is the standard way to allocate test-time compute for code generation, with pass@ as the canonical metric. Yet the standard policy class draws…
MEDUSA: Scalable Biometric Sensing in the Wild through Distributed MIMO Radars
Yilong Li, Ramanujan K Sheshadri, Karthik Sundaresan +2
Radar-based techniques for detecting vital signs have shown promise for continuous contactless vital sign sensing and healthcare applications. However, real-world indoor environmen…
NPUsper: Eliminating Redundant Computation for Real-Time Whisper on Mobile NPUs
Sihyeon Lee, Hojeong Lee, Sungwon Woo +3
We present NPUsper, a live transcription system that makes Whisper efficient on mobile NPUs by eliminating redundant computation. To avoid the heavy padding used by prior streaming…
Tiny but Mighty: A Software-Hardware Co-Design Approach for Efficient Multimodal Inference on Battery-Powered Small Devices
Yilong Li, Shuai Zhang, Yijing Zeng +5
Large Multimodal Models (LMMs) are inherently modular, comprising vision and audio encoders, a projector, and a language backbone. Yet existing systems execute them monolithically,…
Babel: A Scalable Pre-trained Model for Multi-Modal Sensing via Expandable Modality Alignment
Shenghong Dai, Shiqi Jiang, Yifan Yang +4
This paper presents Babel, the expandable modality alignment model, specially designed for multi-modal sensing. While there has been considerable work on multi-modality alignment,…
AGrail: A Lifelong Agent Guardrail with Effective and Adaptive Safety Detection
Weidi Luo, Shenghong Dai, Xiaogeng Liu +4
The rapid advancements in Large Language Models (LLMs) have enabled their deployment as autonomous agents for handling complex tasks in dynamic environments. These LLMs demonstrate…
