Abstract:
The objective of the master’s thesis is to study and refine the model architecture of a previously presented approach for improving the prediction accuracy in each cancer types. This work has four GCNN models which are PPI, PPIS, COEX and COEXS, using data from TCGA of cancer and normal tissue as the input depending on the gene expression. After refinement, the prediction accuracy of four GCNN models achieved the outstanding 89-96% among 34 classes and reduced predictive errors in original model of cancer classes that present problems.
