Learning Causality from Video
This code implements the theory to learn the Causal And-Or Graph from the paper "Learning Perceptual Causality from Video" by Amy Fire and Song-Chun Zhu, 2016. The associated paper and data can be found at http://amyfire.com/projects/learningcausality/.
This code uses a minimax entropy pursuit alongside heuristics to attribute strong correlations as causal.
Source data consists of detections made in 4 scenes--3 different kinds of doorways (
data/Exp1_output_data2.txt) and 1 office scene (
data/Exp2_output_data.txt). Detections were performed by Mingtao Pei.
Output for the paper is produced by running the script
LEARNING.m. It requires the detections above in
