Machine Learning based Framework for Drug Prediction of Cancerous Genomic Profiles

Abstract

Advancement in bioinformatics has raised the patient s life expectancy and boosted the treatment procedure of various stringent diseases. Cancer is one of the genetic diseases caused due to mutation and variation in genes of the patient s cells. Complexity in tumor microenvironment makes cancer difficult disease from the treatment perspective. Patients with the same type of cancer show heterogeneous treatment responses toward the same type of targeted therapies. Clinical trials and the traditional drug discovery process is a time-consuming and tedious task. Hence, researchers are trying their hard to design optimal treatment options for such stringent diseases. Availability of huge amount of oncological and pharmacogenomics online data sources have boosted the research in this field. Recently data mining and machine learning approaches are adding a powerful hand in such a data-driven analysis. In this thesis, we have mentioned diverse areas of personalized cancer therapy using predictive modeling. We have worked in diverse areas of precision medicine such as drug response prediction, drug synergy prediction, drug target-interaction prediction and cancer classification using machine learning approaches. The main objective of this research is to design prediction models for drug sensitivity prediction, drug combination therapy, drug target interaction prediction and cancer classification using machine learning. A cancer classification framework C-HMOSHSSA is proposed using multi-objective meta-heuristic and machine learning approaches to predict relevant and new cancer biomarkers. A hybrid feature selection algorithm (HMOSHSSA) is proposed for gene selection using multi-objective spotted hyena optimizer (MOSHO) and salp swarm algorithm (SSA). Further, four different classifiers are trained on the dataset which is obtained after applying the proposed hybrid gene selection algorithm (HMOSHSSA). The new sets of informative genes are identified by the xiii proposed technique. Next, we have proposed an integrated framew
