基于多源异构数据融合的miRNA与疾病高精度关联预测研究

Accumulating studies have shown that microRNAs (miRNAs) play critical roles in the development and progression of various human complex diseases. Unprecedented attention has been received to the highly accurate and efficient association prediction methods between miRNAs and diseases by using intelligent computing technology. Aiming at "The Study of Highly Accurate Prediction for Associations between miRNAs and Diseases Based on Multi-source Heterogeneous Data Fusion", This project is to adopt tensor decomposition to integrate multi-source heterogeneous biological data to an organic numerical representation scheme, and simulate human brain stratified structure to design the deep network model to automatically abstract feature vector with minimized reconstruction error. Finally, an acute and effective machine learning based prediction model will be constructed to identity the associations between miRNAs and diseases to provide theoretical and technical support for further development of biological experiments and precision medicine.
