Machine learning
We use machine learning approaches in different projects to analyze omics data. We also develop machine learning tools to help biomarker signature identification from disease-derived omics datasets. Omics datasets are generally highly unbalanced, where features largely outnumber samples and the patients are unequally distributed among measured outcomes. The data is also often heterogeneous (e.g. cancer data), of diverse types (e.g. categorical, numerical), and are often sparse. Thus, specific machine learning strategies have to be developed to adapt the special characteristics of omics data.
