Introduction

OmiEmbed is a unified framework for deep learning-based omics data analysis, which supports:

1. Multi-omics integration
2. Dimensionality reduction
3. Omics embedding learning
4. Tumour type classification
5. Phenotypic feature reconstruction
6. Survival prediction
7. Multi-task learning for aforementioned tasks
