Sommario
Tuesday, February 3rd, 2026 at 2:15 pm a new appointment of Data Science Seminars: Bioinformatics focus will take place in DEIB "Alessandra Alario" Seminar Room (Building 21) organized by the Data Science for Bioinformatics group.The seminar will be held by Sergio Lifschitz, Associate Professor in the Department of Computer Science at Pontifícia Universidade Católica do Rio de Janeiro, on the following subject: "A New Data Modeling Approach for Alignment-free Biological Applications".
Identifying and grouping homologous proteins are fundamental tasks in biology, currently dominated by tools that rely on DNA or amino acid sequence data. However, these tasks require the detection of complex evolutionary patterns that are often difficult to capture automatically using traditional methods. This talk presents a data modeling approach that leverages evolutionary patterns for homology searching, ranking, and clustering through an alignment-free process using image similarity algorithms. Our strategy proves valuable even for distant homologs and offers inherent advantages for data privacy and security. Practical experiments show that our approach achieves good and comparable results with traditional methods besides extra visual semantics information.
