Abstract
Purpose: In cancer therapies, drug combinations have shown significant accuracy and minimal side
effects than the single drug administration. Therefore, drug synergy has drawn great interest from
pharmaceutical companies and researchers. Unfortunately, the prediction of drug synergy score was carried out
based on the small group of drugs.
Methods: Due to the advancement in high-throughput screening (HTS), the size of drug synergy datasets has
grown enormously in recent years. Hence, machine learning models have been utilized to predict the drug
synergy score. However, the majority of these machine learning models suffer from over-fitting and hyperparameters
tuning issues.
Results: A novel deep bidirectional mixture density network (BMDN) model is proposed. A dynamic mutationbased
multi-objective differential evolution is used to optimize the hyper-parameters of BMDN. Extensive is
conducted on the NCI-ALMANAC drug synergy dataset that consists of 2,90,000 synergy determinations.
Conclusions: Experimental results reveal that BMDN outperforms the existing drug synergy models in terms of
various performance metrics.
