Completer: Incomplete Multi-view Clustering via Contrastive Prediction

What's New

• We support arbitrary number of views for multi-view clustering and classification tasks. See 2022-TPAMI-DCP for more details.

Intro

This repo contains the code and data of our CVPR'2021 paper Completer: Incomplete Multi-view Clustering via Contrastive Prediction and that of our IEEE TPAMI'2022 paper Dual Contrastive Prediction for Incomplete Multi-view Representation Learning.

COMPLETER: Incomplete Multi-view Clustering via Contrastive Prediction

Dual Contrastive Prediction for Incomplete Multi-view Representation Learning

Requirements

pytorch==1.2.0

numpy>=1.19.1

scikit-learn>=0.23.2

munkres>=1.1.4

Configuration

The hyper-parameters, the training options (including the missing rate) are defined in configure.py.

Datasets

The Caltech101-20, LandUse-21, and Scene-15 datasets are placed in "data" folder. The NoisyMNIST dataset could be downloaded from cloud.

Usage

The code includes:

• an example implementation of the model,
• an example clustering task for different missing rates.

python run.py --dataset 0 --devices 0 --print_num 100 --test_time 5

You can get the following output:
