B-SOiD flowchart

Mouse Action Cluster Demo 1x The dataset from Yttri lab, Alexander Hsu, has been tested against multiple human observers and showed comparable inter-grader variability as another observer.

Mouse Action Cluster Demo 1x We also tested the generalizability with the dataset from Ahmari lab , Jared Kopelman, Shirley Jiang, & Sean Piantadosi, and was predictive of actual behavior.

Why B-SOiD ("B-side")?

DeepLabCut1,2,3 has revolutionized the way behavioral scientists analyze data. The algorithm utilizes recent advances in computer vision and deep learning to automatically estimate 3D-poses. Interpreting the positions of an animal can be useful in studying behavior; however, it does not encompass the whole dynamic range of naturalistic behaviors.

Behavioral segmentation of open field in DeepLabCut, or B-SOID ("B-side"), is an unsupervised learning algorithm in MATLAB/Python that serves to discover behaviors that are not pre-defined by users. Our algorithm can segregate statistically different sub-second rodent behaviors with a single video-camera. Upon estimating the positions, this algorithm agnostically separates statistically significant distributions in the 3-dimensional action space and are found to be correlated with different observable rodent behaviors.

This usage of this algorithm has been outlined below, and is extremely flexible in adapting to what the user wants. With the ever-blooming advances in ways to study an animal behavior, our algorithm builds on and integrates what has already been robustly tested to help advance scientific research.
