Mayank Kabra has shared the following about JAABA, a machine learning-based behavior detection system developed by the Branson Lab at HHMI Janelia Farm.
The Janelia Automatic Animal Behavior Annotator (JAABA) is a machine learning-based system that enables researchers to automatically detect behaviors in video of behaving animals. Through our system, users begin by labeling the behavior of the animal, e.g. walking, grooming, or following, in few of the video frames. Using machine learning, JAABA learns behavior detectors based on these labels that can then be used to automatically classify the behaviors of animals in other videos. JAABA has a fast and intuitive graphical user interface, and multiple ways to visualize and understand the classifier by a non-machine learning user. JAABA has enabled extraction of detailed, scientifically meaningful measurements of the behavioral effects in large experiments.
