On the left is the co-authorship network of Filipino researchers working on deep learning. On the right is the top ten clusters of researchers based on size.

[Left] The co-authorship network of Filipino researchers who have at least one (1) publication on deep learning. Each color represents their affiliation. The largest group of researchers come from De La Salle University (26.44%), comprised of engineering and computing researchers. The second largest group is from the University of the Philippines - Diliman with 15.71% of researchers. [Right] The top 10 cluster of researchers based on size. The biggest cluster is composed of researchers mostly from De La Salle University, working with researchers from the Technological University of the Philippines and University of Santo Tomas.


Deep learning is an emerging field that attracts attention from various researchers to use in analyzing and understanding increasingly complex systems and phenomena. Crucial to the advancement of deep learning research in the Philippines, institutions need to understand its direction and reach out and work with other leading researchers who have knowledge, insight, and resources to contribute to the challenges in deep learning research. Due to its wide application, we analyzed the collaboration dynamics and patterns of Filipino researchers working in this field through their co-authorship network. Our study found that while there is a steady increase in research productivity on deep learning, most of the publications and collaborations are concentrated on a handful of institutions like De La Salle University and University of the Philippines Diliman. Despite their current control over the direction of the local research community, these two top institutions have yet to form strong collaborations. We also found that Filipino researchers are mostly doing applied deep learning projects and rely heavily on undergraduate students to maintain productivity.
