Abstract
A method for training a neural network to cluster multiple people in an image into groups and estimate an activity of each of the groups is provided. The method extracts a feature of each of the multiple people in the image. The method inputs the feature to the neural network to estimate an affinity matrix A and the activity of each of the groups. The method calculates a first loss between the estimated affinity matrix and a ground truth affinity matrix for the image, and a second loss between the estimated activity of each of the groups and a ground truth activity of each of the groups for the image. The first loss is calculated using Maximum Spanning Trees. The method trains the neural network based on the first and second losses.
