Supervised Contrastive Vision Transformer for Breast Histopathological Image Classification

no code implementations17 Apr 2024 Mohammad Shiri, Monalika Padma Reddy, Jiangwen Sun

We present a novel approach, Supervised Contrastive Vision Transformer (SupCon-ViT), for improving the classification of invasive ductal carcinoma in terms of accuracy and generalization by leveraging the inherent strengths and advantages of both transfer learning, i. e., pre-trained vision transformer, and supervised contrastive learning.

Edge Attention-based Multi-Relational Graph Convolutional Networks

1 code implementation14 Feb 2018 Chao Shang, Qinqing Liu, Ko-Shin Chen, Jiangwen Sun, Jin Lu, Jin-Feng Yi, Jinbo Bi

The proposed GCN model, which we call edge attention-based multi-relational GCN (EAGCN), jointly learns attention weights and node features in graph convolution.

VIGAN: Missing View Imputation with Generative Adversarial Networks

1 code implementation22 Aug 2017 Chao Shang, Aaron Palmer, Jiangwen Sun, Ko-Shin Chen, Jin Lu, Jinbo Bi

Especially, when certain samples miss an entire view of data, it creates the missing view problem.

A Sparse Interactive Model for Matrix Completion with Side Information

no code implementations NeurIPS 2016 Jin Lu, Guannan Liang, Jiangwen Sun, Jinbo Bi

We prove that when the side features can span the latent feature space of the matrix to be recovered, the number of observed entries needed for an exact recovery is $O(\log N)$ where $N$ is the size of the matrix.

On Multiplicative Multitask Feature Learning

no code implementations NeurIPS 2014 Xin Wang, Jinbo Bi, Shipeng Yu, Jiangwen Sun

We prove that this framework is mathematically equivalent to the widely used multitask feature learning methods that are based on a joint regularization of all model parameters, but with a more general form of regularizers.
