Abstract

The characterization of drug - metabolizing enzymes is a significant problem for customized therapy. It is important to choose the right drugs for cancer victims, and the ability to forecast how those drugs will react is usually based on the available information, genetic sequence, and structural properties. To the finest of our knowledge, this is the first study to evaluate optimization algorithms for selection of features and pharmacogenetics categorization using classification methods based on a successful evolutionary algorithm using datasets from the Cancer Cell Line Encyclopaedia (CCLE) and Genomics of Drug Sensitivity in Cancer (GDSC). The study proposes the uses of Firefly and Grey Wolf Optimization techniques for feature extraction, while comparing the traditional Machine Learning (ML), ensemble ML and Stacking Algorithm with the proposed Convolutional Temporal Deep Neural Network or CTDN. With the potential to increase efficiency from the suggested intelligible classifier model for a suggestive chemotherapeutic drugs response prediction, our study is important in particular for selecting an acceptable feature selection method. The comparison analysis demonstrates that the proposed model not only surpasses the prior state-of-the-art methods, but also uses Grey Wolf and Fire Fly Optimization to lessen multicollinearity and overfitting.

摘要

药物代谢酶的特征描述是定制治疗的一个重大问题。为癌症患者选择合适的药物非常重要,而预测这些药物反应的能力通常基于现有信息、遗传序列和结构特性。据我们所知,这是第一项使用基于成功进化算法的分类方法,利用癌症细胞系百科全书(CCLE)和癌症药物敏感性基因组学(GDSC)数据集评估特征选择和药物遗传学分类的优化算法的研究。该研究提出了使用萤火虫和灰狼优化技术进行特征提取,同时将传统机器学习(ML)、集成机器学习和堆叠算法与提出的卷积时间深度神经网络或 CTDN 进行比较。通过对有希望的化疗药物反应预测的建议可理解分类器模型提高效率的潜力,我们的研究对于选择可接受的特征选择方法尤其重要。比较分析表明,所提出的模型不仅超越了先前的最先进方法,而且还使用灰狼和萤火虫优化来减少多重共线性和过拟合。
