Background: The integration and interpretation of multi-omics data are crucial in elucidating the pathophysiological mechanisms of complex diseases. While Deep Neural Networks (DNNs) and Graph Neural Networks (GNNs) have revolutionized the analysis of such data in cancer and neurodegenerative diseases, there remains a critical need for improved multi-omics analytic methodologies. Methods: We developed OmicsFootPrint, a novel framework for transforming multi-omics data into two-dimensional circular images for each sample, enabling intuitive representation and analysis. Utilizing DNNs for analysis, this framework incorporates the SHapley Additive exPlanations (SHAP) algorithm for model interpretation. We benchmarked OmicsFootPrint performance with data sets from The Cancer Genome Atlas (TCGA); we classified subtypes of lung cancer and breast cancer, specifically the PAM50 subtype and histological classifications. Additionally, we applied OmicsFootPrint to predict drug response data in cancer cell lines. Results: Evaluation of lung cancer subtypes using TCGA data sets, OmicsFootPrint achieved an average Area Under Curve (AUC) of over 0.90 for distinguishing between lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) subtypes. Notably, the EfficientNetV2 model reached an AUC of 0.98±0.02. For the TCGA BRCA (breast cancer) PAM50 subtype classification, encompassing Luminal A, Luminal B, Basal, and HER2 subtypes (836 samples in total), the framework reported an average AUC of 0.83±0.07. Furthermore, the application of OmicsFootPrint to the BRCA data set for distinguishing between invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC) showed an average AUC of 0.87±0.04 with four-omics datatypes. Additionally, in drug response studies, OmicsFootPrint outperformed published algorithms, achieving the highest average AUC of 0.74 across all data sets. OmicsFootPrint also demonstrated robust performance with reduced training sample sizes. Conclusions: OmicsFootPrint represents a significant advancement, offering a comprehensive, efficient, and interpretable framework for multi-omics data analysis. Its innovative approach in transforming extensive multi-omics data sets into compact, circular images not only reduces memory requirements but also enhances the interpretability of complex biological data. This approach facilitates personalized treatment strategies and enriches our understanding of disease mechanisms, marking a significant step forward in the field of multi-omics research.
