The Computational Science Research Center (CSRC), in partnership with the Numerical Analysis and Scientific Computing (NASC) Academic Group, the University of the Philippines Intelligent Systems Center (UP ISC), and the UP Diliman Mathematics Foundation Inc. (UPDMFI), successfully organized the CoMaDS 2025: International Workshop on Computational and Mathematical Methods in Data Science, held at Boracay Tropics Resort Hotel, Aklan, Philippines from April 3-5, 2025.

CoMaDS 2025 was also supported by Kanazawa University, Japan, and Institut Teknologi Bandung, Indonesia. Additionally, it was financially supported by the UP Office of International Linkages (OIL) through the OIL Hosting and WELS grants, as well as the UPD Extension Grant of the UP Diliman Office of the Vice Chancellor for Research and Development (OVCRD) through the Office of Extension Coordination (OEC).

This workshop gathered researchers and experts from the Philippines and abroad to showcase cutting-edge methodologies in data science and artificial intelligence, focusing on innovative approaches in data-driven research, modeling, and optimization.

Participants took part in the 3-day workshop, which featured lectures, hands-on computational exercises, scientific talks, and poster presentations. On the first day of the program, selected poster presenters showcased their research to fellow participants and invited speakers during a dedicated poster session. Topics covered a broad spectrum, including machine learning, scientific computing, mathematical modeling, artificial intelligence, and data science, reflecting the interdisciplinary nature of the workshop. The session encouraged active discussion and knowledge exchange, allowing presenters to receive valuable feedback and build academic connections. Toward the conclusion of the workshop, participants engaged in collaborative discussions and meaningful networking activities.

Dr. Renier G. Mendoza, CSRC Program Director and CoMaDS 2025 Workshop Chair, attended the event with key CSRC team members. Mr. Roberto Eugenio, Jr. and Mr. Reynaldo Yabut, Jr. handled registration and administrative support—Mr. Eugenio being the proponent of the OILS Hosting and WELS grants, and Mr. Yabut a project staff member for CSRC research grants. Mr. Ace Reario and Mr. Augusto Gayon managed technical support, while Ms. Kloudene Salazar, Mr. Rodney Pino, and Mr. Junel Isanan joined as participants.
