The detection of exons is an important area of research in genomic sequence analysis. Many signal-processing methods have been established successfully for detecting the exons based on their periodicity property. However, some improvement is still required to increase the identification accuracy of exons. So, an efficient computational model is needed. Therefore, for the first time, we are introducing an optimized convolutional neural network (optCNN) for classifying the exons and introns. The study aims to identify the best CNN model that provides improved accuracy for the classification of exons by utilizing the optimization algorithm. In this case, an African Vulture Optimization Algorithm (AVOA) is used for optimizing the layered architecture of the CNN model along with its hyperparameters. The CNN model generated with AVOA yielded a success rate of 97.95% for the GENSCAN training set and 95.39% for the HMR195 dataset. The proposed approach is compared with the state-of-the-art methods using AUC, F1-score, Recall, and Precision. The results reveal that the proposed model is reliable and denotes an inventive method due to the ability to automatically create the CNN model for the classification of exons and introns.
外显子的检测是基因组序列分析中的一个重要研究领域。基于外显子的周期性特性,已经成功建立了许多信号处理方法来检测外显子。然而,仍需要一些改进来提高外显子的识别准确率。因此,需要一个高效的计算模型。所以,我们首次引入了一种优化的卷积神经网络(optCNN)来对外显子和内含子进行分类。该研究旨在通过利用优化算法来识别能够提高外显子分类准确率的最佳卷积神经网络模型。在这种情况下,使用非洲秃鹫优化算法(AVOA)来优化卷积神经网络模型的分层架构及其超参数。用AVOA生成的卷积神经网络模型在GENSCAN训练集上的成功率为97.95%,在HMR195数据集上的成功率为95.39%。使用AUC、F1分数、召回率和精确率将所提出的方法与当前最先进的方法进行比较。结果表明,所提出的模型是可靠的,并且由于能够自动创建用于外显子和内含子分类的卷积神经网络模型,所以是一种创新方法。
