SoleSense: A Shoe-Based Wearable for Sound Event Localization and Detection in Urban Environments

Detecting and localizing acoustic events from a person or device is important for a wide range of applications, including improving pedestrian safety, increasing situational awareness, or for interacting with digital assistants. Compared to radio frequency waves, acoustic waves are naturally more affected and attenuate...

PELM: Power Efficient On-Device LLM Inference with Speculative Decoding and Dynamic Voltage Frequency Scaling

PELM is presented, a solution that augments traditional DVFS processor frequency tuning with two additional workload-specific knobs: speculative decoding and variable verification depth to expand the optimization space to multiple dimensions for more power efficient on-device LLM inference.
