Source-Learned Reliance for Selective Test-Time Adaptation of Multimodal Time Series

This work proposes CARAT, which decouples model reliance from runtime corruption detection to guide omission or attenuation, amortizing reliance estimation through source training and position CARAT as a practical default to wearable TTA, offering competitive robustness with modest computational requirements and benefi...

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.
