Unifying Background Models over Complex Audio using Entropy
TL;DR: This paper proposes a method incorporating further information, the proximity of distributions determined using entropy, to determine a more complete background model, which was successful in more robustly modelling the background for complex audio scenes.

Viewpoint distortion compensation in practical surveillance systems
TL;DR: In this paper, the perspective-effected geometric distortion of a scene from a video feed is estimated using low-level, spatio-temporally local motion features used in commercial semi-automatic surveillance systems.

Estimating support scores of autism communities in large-scale web information systems
TL;DR: The ASD subreddit was found to be a supportive community, having far higher support scores than did the average subreddit, and Scalable machine learning techniques implemented in Spark help discriminate the content made in Aspergers versus other subreddits and automatically discover linguistic predictors of ASD within minutes, providing timely reports.
Proceedings ArticleDOI
Sparse Subspace Representation for Spectral Document Clustering
TL;DR: A ℓ1-norm optimization formulation is posed to learn the sparse representation of each document, allowing us to characterize the affinity between documents by considering the overall information instead of traditional pair wise similarities.
