LERENet: Eliminating Intra-class Differences for Metal Surface Defect Few-shot Semantic Segmentation

no code implementations17 Mar 2024 Hanze Ding, Zhangkai Wu, Jiyan Zhang, Ming Ping, Yanfang Liu

Since the relation structure of local features embedded in graph space will help to eliminate \textit{Semantic Difference}, we employ Multi-Prototype Reasoning (MPR) module, extracting local descriptors based prototypes and analyzing local-view feature relevance in support-query pairs.

Deep Bayesian Reinforcement Learning for Spacecraft Proximity Maneuvers and Docking

no code implementations7 Nov 2023 Desong Du, Naiming Qi, Yanfang Liu, Wei Pan

This innovative approach allows the state-value function to be expressed as a Lyapunov function, leveraging the Gaussian process and deep kernel learning.

Diffusion-Model-Assisted Supervised Learning of Generative Models for Density Estimation

no code implementations22 Oct 2023 Yanfang Liu, Minglei Yang, Zezhong Zhang, Feng Bao, Yanzhao Cao, Guannan Zhang

Unlike existing diffusion models that train neural networks to learn the score function, we develop a training-free score estimation method.

Contrastive Prompt Learning-based Code Search based on Interaction Matrix

no code implementations10 Oct 2023 Yubo Zhang, Yanfang Liu, Xinxin Fan, Yunfeng Lu

However, existing code search methods still suffer from two performance constraints: inadequate semantic representation and the semantic gap between natural language (NL) and programming language (PL).

Seeking the Yield Barrier: High-Dimensional SRAM Evaluation Through Optimal Manifold

no code implementations28 Jul 2023 Yanfang Liu, Guohao Dai, Wei W. Xing

We then generalize it with infinite components and derive the novel optimal manifold concept, which bridges the surrogate-based and importance sampling (IS) yield estimation methods.

A Multilayer Framework for Online Metric Learning

1 code implementation15 May 2018 Wenbin Li, Yanfang Liu, Jing Huo, Yinghuan Shi, Yang Gao, Lei Wang, Jiebo Luo

Furthermore, in a progressively and nonlinearly learning way, MLOML has a stronger learning ability than traditional online metric learning in the case of limited available training data.
