Abstract:The identification of motifs is a crucial stage in the process of exploring the function of genes in many different systems. The identification of transcription factor binding sites (TFBSs), is an crucial step in the process of comprehending the regulatory mechanisms that regulate gene expression. Motif discovery is an essential step in this process. However, existing motif discovery methods face challenges such as computational complexity, sensitivity to parameters, and assumptions about motif characteristics. As a consequence, we introduced the Modified Freeze Firefly method for motif discovery based on Gibbs sampling, as well as the Harmony Search with Logistic regression for predicting. This research is distinctly focused on harnessing the power of Artificial Intelligence (AI) algorithms tailored to refine and optimize precision in motif identification. The methodology begins with the acquisition of data from the JASPAR database, followed by meticulous preprocessing. Motif discovery is then executed using the Modified Freeze Firefly with Gibbs Sampling (MFF-GS). Subsequently, the identified motifs undergo a precision enhancement and refinement process through the innovative Harmony Search with Logistic Regression (HS-LR). Finally, the performance metrics are rigorously evaluated, encompassing Running time vs. Maximum Motif length, running time vs. Motif length, running time vs. motif count (d), Prediction rate, and Mean Square Error. This comprehensive approach signifies a cutting-edge integration of AI techniques, promising to elevate the accuracy and effectiveness of motif refinement in the context of gene regulation studies.
