Abstract: Deep learning has benefits to find complicated interactions between biological entities and could make useful estimation. In clinical practice, the prediction of platinum resistance in ovarian cancer is an important problem because it alters treatment options for patients and subsequently their quality of life. In this paper, Deep Neural Network (DNN) models are designed and evaluated with several feature selection approaches. Among the feature selection approaches, genes selected by group difference in gene expression showed the best performance of 0.838 in test accuracy and 0.889 in test AUC. Hybrid ensemble approaches displayed a performance of 0.903 in test accuracy and 0.869 in test AUC. An alternative hybrid ensemble model with removed partially sensitive samples displayed the performance of 0.903 in test accuracy and 0.914 in test AUC. These results suggest that a hybrid ensemble approach could help prediction of platinum resistance in ovarian cancer and subsequent treatment practice in clinics.
