Machine Learning Technologies for Wide Area Search
Wide area sensors, such as Wide Area Motion Imagery (WAMI), Ground Moving Target Indicator (GMTI) radars, satellite imagery, provide information about movements in large areas. These sensors play important role in ground operations, border protection, and maritime surveillance. Due to relatively low spatial resolution of the data, detection and tracking in such data is challenging not only to computer algorithms but to human analysts as well [Ling 2011].
We will describe machine learning technologies for target detection and characterization, activity detection, and tracking in wide area sensor data. We address challenges in ground truth collection through collaboration with analysts and co-collects from multiple sensors. We will also describe development of two new learning technologies that address challenges of providing robust decision rules for such practical applications with limited amount of ground truth.
Feature Clustering (FC) groups features into separate clusters, based on the feature inter-correlations. Thus, FC enables partitioning of the classification problem into approximately independent sub-problems. The feature space partitioning enables solving each sub-problem independently and then fusing results into one final classifier [Kuncheva 2014].
In the Learning Under Privileged Information (LUPI) paradigm [Vapnik 2009, 2015; Streltsov 2014; Ilin 2016], a Teacher supplies students with additional information that is available during training only. LUPI algorithms allow better generalization from a small number of training samples.
This is joint work with Ilya Muchnik, Yuri Goncharov, Alan Gove, Steve Bento.
