Masked AutoEncoder for Graph Clustering without Pre-defined Cluster Number k

no code implementations9 Jan 2024 Yuanchi Ma, Hui He, Zhongxiang Lei, Zhendong Niu

However, for existing graph autoencoder clustering algorithms based on GCN or GAT, not only do they lack good generalization ability, but also the number of clusters clustered by such autoencoder models is difficult to determine automatically.

Robust Few-Shot Named Entity Recognition with Boundary Discrimination and Correlation Purification

1 code implementation13 Dec 2023 Xiaojun Xue, Chunxia Zhang, Tianxiang Xu, Zhendong Niu

However, the present few-shot NER models assume that the labeled data are all clean without noise or outliers, and there are few works focusing on the robustness of the cross-domain transfer learning ability to textual adversarial attacks in Few-shot NER.

Frequency-domain MLPs are More Effective Learners in Time Series Forecasting

1 code implementation NeurIPS 2023 Kun Yi, Qi Zhang, Wei Fan, Shoujin Wang, Pengyang Wang, Hui He, Defu Lian, Ning An, Longbing Cao, Zhendong Niu

FreTS mainly involves two stages, (i) Domain Conversion, that transforms time-domain signals into complex numbers of frequency domain; (ii) Frequency Learning, that performs our redesigned MLPs for the learning of real and imaginary part of frequency components.

Knowledge Aware Semantic Concept Expansion for Image-Text Matching

no code implementations International Joint Conferences on Artifical Intelligence (IJCAI) 2019 Botian Shi, Lei Ji, Pan Lu, Zhendong Niu, Nan Duan

In this paper, we develop a Scene Concept Graph (SCG) by aggregating image scene graphs and extracting frequently co-occurred concept pairs as scene common-sense knowledge.
