A method for constructing a disease prediction model is provided. First, a genome-wide association study (GWAS) is conducted on patients with the target disease to identify relevant SNP loci. Next, two SNP loci are randomly selected as a first SNP combination, and a first machine learning model is trained for disease prediction, with its accuracy verified. Subsequently, the remaining SNP loci are sequentially added to the first combination to generate multiple second SNP combinations, and the corresponding disease prediction models are trained and validated. Among these second combinations, the one with the highest prediction accuracy is selected as the third combination. This process is repeated until all SNP loci are included, ultimately determining the optimal SNP target combination for the final training and prediction of the disease prediction model.

Provided are methods, systems and computer program product embodiments for analyzing multi-omic data using a tensor regression model for genome-wide association studies in the life sciences. The unique structure of tensor covariates is leveraged to find associations between the omics data and complex diseases. Within this framework, the excessive dimensionality is reduced to a manageable level, leading to efficient estimations and predictions. The method is superior to using classical regression techniques in genome-wide association studies, which are challenged by analyzing multi-dimensional and uniquely structured data from the health and life sciences, in which covariates can take on more intricate forms such as multi-dimensional arrays. Embodiments have multiple uses in genomics, proteomics, metabolomics, multi-omics data integration, drug discovery, personalized medicine and predictive modeling, demonstrating the versatility and importance of tensor regression models to understand the associations between omics data and complex diseases.
