摘要:

生物序列分析是建立对序列的潜在功能,结构和行为的更深入理解的重要一步。它可以帮助识别相关生物体的特征,如病毒等,并建立预防机制,以消除其传播和影响,因为众所周知,病毒会引起流行病,并可能成为全球性的流行病。机器学习(ML)技术为生物序列分析提供了新的工具,以有效地分析序列的功能和结构。然而,这些基于ML的方法经历了数据不平衡的挑战,通常与生物序列数据集相关,这阻碍了它们的性能。尽管存在各种策略来解决这个问题,例如创建合成数据的SMOTE算法,但是,它们关注局部信息而不是整体类分布。在这项工作中,我们探索了一种新的方法来处理数据不平衡问题的基础上生成对抗网络(GANs),使用整体数据分布。GANs用于生成与真实数据非常相似的合成数据,因此可以使用该生成的数据通过消除生物序列分析的类不平衡问题来增强ML模型的性能。我们通过使用3种不同的序列数据集(甲型流感病毒,PALMdb,VDjDB)执行3种不同的分类任务,我们的结果表明,GANs可以提高整体分类性能。

英文摘要:

Biological sequence analysis is an essential step toward building a deeper understanding of the underlying functions, structures, and behaviors of the sequences. It can help in identifying the characteristics of the associated organisms, like viruses, etc., and building prevention mechanisms to eradicate their spread and impact, as viruses are known to cause epidemics that can become pandemics globally. New tools for biological sequence analysis are provided by machine learning (ML) technologies to effectively analyze the functions and structures of the sequences. However, these ML-based methods undergo challenges with data imbalance, generally associated with biological sequence datasets, which hinders their performance. Although various strategies are present to address this issue, like the SMOTE algorithm, which creates synthetic data, however, they focus on local information rather than the overall class distribution. In this work, we explore a novel approach to handle the data imbalance issue based on Generative Adversarial Networks (GANs) which use the overall data distribution. GANs are utilized to generate synthetic data that closely resembles the real one, thus this generated data can be employed to enhance the ML models' performance by eradicating the class imbalance problem for biological sequence analysis. We perform 3 distinct classification tasks by using 3 different sequence datasets (Influenza A Virus, PALMdb, VDjDB) and our results illustrate that GANs can improve the overall classification performance.
