Lethe: Layer- and Time-Adaptive KV Cache Pruning for Reasoning-Intensive LLM Serving

AAAI 2026technical

Generative reasoning with large language models (LLMs) often involves long decoding sequences, leading to substantial memory and latency overheads from accumulating key-value (KV) caches. While existing KV compression methods primarily focus on reducing prefill memory from long input sequences, they

Training Verification-Friendly Neural Networks via Neuron Behavior Consistency

AAAI 2025technical

Formal verification provides critical security assurances for neural networks, yet its practical application suffers from the long verification time. This work introduces a novel method for training verification-friendly neural networks, which are robust, easy to verify, and relatively accurate. Our…

Uncertainty-Driven Expert Control: Enhancing the Reliability of Medical Vision-Language Models

ICCV 2025poster

The rapid advancements in Vision Language Models (VLMs) have prompted the development of multi-modal medical assistant systems. Despite this progress, current models still have inherent probabilistic uncertainties, often producing erroneous or unverified responses--an issue with serious implications…

A Novel SEA-based Haptic Interface for Robot-Assisted Vascular Interventional Surgery

ICRA 2024poster

Robot-assisted vascular interventional surgery can isolate interventionists and X-ray radiation, and improve surgical accuracy. However, the leader side outside the operating room still has problems such as incomplete collection of operating information and unrealistic tactile feedback. The main obj…

Flexible Tactile-Sensing Gripper Design and Excessive Force Protection Function for Endovascular Surgery Robots

RA-L 2023

Research on endovascular surgery robots (ESR) is continuously developing, because ESR can protect surgeons from radiation exposure. For designing an ESR manipulator, the main challenge is controlling the soft surgical tools and measuring the endovascular stress simultaneously. In this letter, a flex

Universal Hypothesis Testing with Kernels: Asymptotically Optimal Tests for Goodness of Fit

AISTATS 2019poster

We characterize the asymptotic performance of nonparametric goodness of fit testing. The exponential decay rate of the type-II error probability is used as the asymptotic performance metric, and a test is optimal if it achieves the maximum rate subject to a constant level constraint on the type-I er…
