Deep learning has shown promise in addressing challenges in big data analytics, including scalability, high-dimensional data, and the integration of diverse data types (Najafabadi et al., 2015; Shukla et al., 2021). 4.2 Statistical methods Statistical methods play a crucial role in the preprocessing and analysis of big data in biology. Techniques such as data normalization, transformation, and noise reduction are essential for preparing data for further analysis. Methods like the Box-Cox transformation and linear transformation have been shown to improve the performance of machine learning algorithms by making the data more consistent and noise-free (Rahman, 2019). Additionally, statistical models such as the hidden Markov model (HMM) are used for sequence analysis and have demonstrated high accuracy and reliability in biological data analysis (Rahman, 2019). 4.3 Network analysis Network analysis is a powerful tool for understanding the complex interactions within biological systems. By representing biological entities (e.g., genes, proteins) as nodes and their interactions as edges, network analysis can reveal the underlying structure and dynamics of biological networks. Techniques such as graph-based algorithms and network-based clustering are used to identify key components and modules within these networks (Kashyap et al., 2015; Jin et al., 2020). Deep learning approaches have also been integrated with network analysis to handle large and heterogeneous graph data structures, enabling the extraction of meaningful information from complex biological networks (JaseenaK and Kovoor, 2018; Jin et al., 2020). This integration has facilitated advancements in areas such as disease network analysis, drug discovery, and the identification of therapeutic targets (Kashyap et al., 2015; Jin et al., 2020). 5 Applications of Big Data Analytics in Biology 5.1 Genomics and transcriptomics Big data analytics has significantly impacted the fields of genomics and transcriptomics, enabling researchers to handle and interpret vast amounts of data generated by high-throughput sequencing technologies. The integration of big data analytics in genomics has facilitated the rapid sequencing of genomes, which was exemplified by the Human Genome Project. This project, which initially took 13 years and over $3 billion, can now be accomplished in just a few days for a fraction of the cost (Li and Chen, 2014). The development of next-generation sequencing (NGS) technologies, such as whole-genome sequencing (WGS) and whole-exome sequencing (WES), has further accelerated the generation of genomic data, allowing for comprehensive studies of genetic variations and their implications in various biological processes and diseases (Hien et al., 2021). Machine learning algorithms have been particularly useful in the analysis of genomic data, providing tools for the annotation of sequence elements and the integration of epigenetic, proteomic, and metabolomic data (Libbrecht and Noble, 2015). These algorithms help in identifying clinically actionable genetic variants, which are crucial for the development of personalized medicine (He et al., 2017). The integration of genomic data with electronic health records (EHRs) has also opened new avenues for individualized diagnostic and therapeutic strategies, although it presents challenges in data manipulation and management (He et al., 2017). 5.2 Proteomics and metabolomics Proteomics and metabolomics are other critical areas where big data analytics have made substantial contributions. The advancements in mass spectrometry and other analytical methods have increased the intersection between proteomics and big data science, enabling the generation of large-scale proteomic and metabolomic datasets (Perez-Riverol and Moreno, 2019). The integration of these datasets with transcriptomic data provides a more comprehensive understanding of biological systems, as it allows for the analysis of gene expression, protein translation, and post-translational modifications in a unified manner (Kumar et al., 2016). High-throughput strategies, such as the sample preparation for multi-omics technologies (SPOT), have been developed to enhance the efficiency of multiomic analyses. These strategies enable the simultaneous analysis of transcriptomic, proteomic, and metabolomic data from a common sample, thereby reducing the resources required
