NCI U01 CA-202144: Multi-Tensor Decompositions for Personalized Cancer Diagnostics and Prognostics1




Inventors of the "eigengene,"2,3,4,5,6,7,8  we formulate physics-inspired9,10,11,12,13,14  multi-tensor15,16  generalizations17,18,19,20,21  of the singular value decomposition to (i) compare and integrate any data types, of any number and dimensions, and (ii) scale with data sizes. Our models (iii) are interpretable in terms of known biology and batch effects and (iv) correctly22  predict23,24,25,26,27  previously unknown mechanisms.28,29,30  By validating a genome-wide pattern of DNA copy-number alterations in brain31,32,33,34,35  tumors as the best predictor of survival, our retrospective clinical trial36,37  proved that the models (v) discover accurate, precise, and actionable genotype-phenotype relationships, (vi) are relevant to populations based upon whole genomes of small cohorts, and (vii) can be validated. We discovered this, and patterns in lung,38,39  nerve, ovarian,40,41,42,43,44,45  and uterine tumors, in public data. Such alterations were recognized in cancer, yet attempts to associate them with outcome failed, demonstrating that our algorithms are uniquely suited to personalized medicine.
