Background:

Next-generation sequencing (NGS) generates vast biological data, but increased speed and affordability lead to more errors.
Data quality assurance is shifting from hardware to software preprocessing stages.
Effective error detection and filtration are crucial for reliable NGS data analysis.

Purpose of the Study:

To introduce MAC-ErrorReads, a novel Machine learning-Assisted Classifier for filtering erroneous NGS reads.
To evaluate the performance of machine learning algorithms in identifying and removing low-quality reads.
To enhance the accuracy and reliability of genomic data.

Main Methods:

Developed MAC-ErrorReads, a binary classification model using five supervised machine learning algorithms.
Extracted features using Term Frequency-Inverse Document Frequency (TF_IDF) from diverse biological datasets.
Trained and tested models on datasets including E. coli, S. aureus, H. Chr14, Arabidopsis thaliana Chr1, and M. zebra.

Main Results:

Naive Bayes (NB) within MAC-ErrorReads demonstrated robust performance across datasets with high accuracy, precision, recall, and F1-scores.
MAC-ErrorReads NB achieved a 38.69% alignment rate for S. aureus reads, outperforming many error correction tools.
MAC-ErrorReads showed competitive alignment rates (e.g., >99% for H. Chr14, ~90% for A. thaliana Chr1, ~83% for M. zebra) compared to other tools.

Conclusions:

Machine learning effectively filters NGS reads, significantly improving assembly quality and genomic coverage.
Integrating artificial intelligence with genomics enhances NGS data quality and downstream analysis.
This approach holds promise for advancing genetics, genomics, and personalized medicine research.
