{"cited_by_count":102602,"description":"This cluster of papers focuses on the application of signal processing techniques to analyze genomic data, including DNA sequences and protein sequences. It explores methods such as graphical representation, numerical characterization, chaos game representation, wavelet analysis, periodicity analysis, and fractal analysis. The cluster also delves into the use of machine learning for genomic signal processing.","display_name":"Fractal and DNA sequence
