Fabian Caba Heilbron

I am a Research Scientist at Adobe Research. I recieved my Ph.D. from KAUST under the supervision of Professor Bernard Ghanem. I was fortunate to work with Juan Carlos Niebles during my master studies at Universidad del Norte.

My research interests span computer vision and machine learning. Specifically, my research focuses in the developments of models to recognize and detect human activities from videos. Some of my previous efforts include:

  • gathering large-scale video datasets
  • developing efficient scanning methods for video analysis
  • training models for temporal activity localization

Professional Experience

ActivityNet Challenge [2016-Present]: I am one of the leading forces behind organizing the ActivityNet Challenge. I built the infrastructure that allows multiple researchers to test-bed their methods. The challenge has attracted a large number of researchers, and it has been sponsored by several companies including DeepMind, Facebook, and Google AI.

Mantis AI [2017-Present]: I am a co-founder of Mantis AI. Mantis crafts ground-breaking research in deep-learning to perform activity detection and video summarization for content-aware ad placement.

IVUL [2015-2019]: I was a Research Assistant at IVUL. My work aimed to develop models for human activity understanding. Some of my efforts were published at top-tier computer vision conferences (see Publications).

Adobe Research [Summer 2017, Summer 2018]: I was an intern for two consecutive summers at Adobe Research. During these periods I developed: (i) an active learning method for action detection; (ii) a navigation system for video editing purposes.
