Deep learning frameworks can process and analyze large-scale sequencing data, enabling the discovery of novel genomic features and the interpretation of complex biological processes. For example, deep learning models have been used to integrate multi-omics data, such as genomics, epigenomics, and transcriptomics, to provide a comprehensive understanding of cellular mechanisms (Min et al., 2016; Talukder et al., 2020). This integration has facilitated advancements in precision medicine by allowing for the detailed analysis of individual genetic profiles and the identification of potential therapeutic targets (Cao et al., 2020; Koumakis, 2020). 3.2 Protein structure prediction Deep learning has also made significant strides in the prediction of protein structures, a fundamental challenge in bioinformatics. By utilizing deep neural networks, researchers have been able to predict the three-dimensional structures of proteins with unprecedented accuracy. These models can learn from vast amounts of protein sequence and structure data, enabling the prediction of protein folding patterns and interactions. The success of deep learning in this domain has been exemplified by models such as AlphaFold, which have achieved remarkable performance in protein structure prediction competitions (Libbrecht and Noble, 2015; Min et al., 2016). The ability to accurately predict protein structures has profound implications for understanding biological functions and designing new drugs. 3.3 Drug discovery and design In the realm of drug discovery and design, deep learning has emerged as a powerful tool for identifying potential drug candidates and optimizing their properties. Deep learning models can analyze large datasets of chemical compounds and biological targets to predict the efficacy and safety of new drugs. These models have been used to screen vast libraries of compounds, identify promising drug candidates, and optimize their chemical structures for better performance (Min et al., 2016; Cao et al., 2020). The integration of deep learning with bioinformatics has accelerated the drug discovery process, reducing the time and cost associated with developing new therapeutics and enabling the discovery of novel treatments for various diseases (Li et al., 2019; Wang et al., 2023). 4 Challenges in Applying Deep Learning to Bioinformatics 4.1 Data quality and availability 4.1.1 Dealing with noisy and incomplete data One of the primary challenges in applying deep learning to bioinformatics is the presence of noisy and incomplete data. Biological datasets often contain errors, missing values, and inconsistencies due to the limitations of experimental techniques and the complexity of biological systems. These issues can significantly affect the performance of deep learning models, leading to inaccurate predictions and unreliable results. Strategies to mitigate these problems include data cleaning, imputation techniques, and robust model training methods that can handle noise and missing data effectively (Min et al., 2016; Lan et al., 2018; Saha et al., 2023). 4.1.2 Strategies for data augmentation Data augmentation is a crucial technique to enhance the quality and quantity of training data, especially when dealing with limited datasets. In bioinformatics, data augmentation can involve generating synthetic data, applying transformations to existing data, or using domain-specific knowledge to create new training examples. These strategies help in improving the generalization ability of deep learning models and reducing overfitting. For instance, techniques such as generative adversarial networks (GANs) and variational autoencoders (VAEs) have been employed to generate realistic biological data, thereby augmenting the training datasets (Li et al., 2019; Tang et al., 2019; Jin et al., 2020). 4.1.3 Access to large and diverse datasets The effectiveness of deep learning models heavily relies on the availability of large and diverse datasets. However, in bioinformatics, obtaining such datasets can be challenging due to privacy concerns, data sharing restrictions, and the high cost of data generation. Collaborative efforts and open-access initiatives are essential to overcome
