Surrogate Prompt Learning: Towards Efficient and Diverse Prompt Learning for Vision-Language Models

ICML 2025poster

Prompt learning is a cutting-edge parameter-efficient fine-tuning technique for pre-trained vision-language models (VLMs). Instead of learning a single text prompt, recent works have revealed that learning diverse text prompts can effectively boost the performances on downstream tasks, as the divers…

Point Deformable Network with Enhanced Normal Embedding for Point Cloud Analysis

AAAI 2024technical

Recently MLP-based methods have shown strong performance in point cloud analysis. Simple MLP architectures are able to learn geometric features in local point groups yet fail to model long-range dependencies directly. In this paper, we propose Point Deformable Network (PDNet), a concise MLP-based ne…

Multi-scale Spatial Representation Learning via Recursive Hermite Polynomial Networks

IJCAI 2022poster

Multi-scale representation learning aims to leverage diverse features from different layers of Convolutional Neural Networks (CNNs) for boosting the feature robustness to scale variance. For dense prediction tasks, two key properties should be satisfied: the high spatial variance across convolutiona…
