报告摘要：
Recent years have witnessed the convergence of multiscale and multimodal brain imaging and omics techniques, showing great promise for systematic and precision medicine. In the meantime, they bring significant data analysis challenges when integrating and mining these large volumes of heterogeneous datasets. In this work, we first introduce a linear collaborative learning model to combine both regression and correlation analysis such as canonical correlation analysis (CCA). To further capture complex interactions both within and across modalities, we develop an interpretable multimodal deep learning-based integration model to perform heterogeneous data integration and result interpretation simultaneously. The proposed model can generate interpretable activation maps to quantify the contribution of imaging or omics features. Moreover, the estimated activation maps are class-specific, which can therefore facilitate the identification of biomarkers. Finally, we apply and validate the model in the study of brain development with integrative analysis of multi-modal brain imaging and genomics data. We demonstrate its successful application to both the classification of cognitive function groups and the discovery of underlying genetic mechanisms.
