Saúl Calderón Ramírez
Saúl Calderón Ramírez is one of the most active deep learning researchers in Costa Rica. He is a professor and researcher at the Costa Rica Institute of Technology (TEC) and leads the PARMA group, devoted to pattern recognition and machine learning.
Key facts
- Institution: Costa Rica Institute of Technology (TEC), School of Computer Engineering.
- Role: Professor and researcher; lead researcher of the PARMA group.
- Field: Deep learning, semi-supervised and self-supervised learning, uncertainty quantification, biomedical images.
- Education: Doctorate in Computer Science (De Montfort University, United Kingdom).
Why he is a leader
There is a difference between using artificial intelligence and understanding it from the inside. Calderón works at the second level: methods. His research centers on one of deep learning’s most real problems, learning when labeled data is scarce, which is common in medical settings where obtaining thousands of expert-classified examples is expensive and slow.
He is the lead author of a review article on semi-supervised deep learning with distribution mismatch, a reference work for those researching how to train models with little reliable data. And he does not stop at theory: he led a real case of mammogram classification using semi-supervised learning applied in a Costa Rican clinic, taking the method to where it truly matters.
His contribution to the ecosystem
Calderón represents a generation of Costa Rican researchers trained abroad who return to produce from within the country and connect Costa Rica with the global AI conversation. His participation in international gatherings in the field helps make local work visible and shows TEC students that the research frontier can be reached from here too.
