Diffusion Trajectory-Guided Policy for Long-Horizon Robot Manipulation

ICRA 2026poster

Recently, Vision-Language-Action Models (VLA) have advanced robot imitation learning, but high data collection costs and limited demonstrations hinder generalization and current imitation learning methods struggle in out-of-distribution scenarios, especially for long-horizon tasks. A key challenge i…

Unveiling the Knowledge of CLIP for Training-Free Open-Vocabulary Semantic Segmentation

AAAI 2025technical

Training-free open-vocabulary semantic segmentation aims to explore the potential of frozen vision-language models (VLM) for segmentation tasks. Recent works reform the inference process of CLIP and utilize the features from the final layer to reconstruct dense representations for segmentation, dem…

Improving Acoustic Echo Cancellation by Mixing Speech Local and Global Features with Transformer

ICASSP 2023accepted

We propose MiT-Net, a novel mix-transformer neural network with a pyramid encoder operating in the time domain, for the task of acoustic echo cancellation. The MiT-Net formulates acoustic echo cancellation as a supervised speech separation problem, in which near-end speech is separated from a single…
