Description:
Machine learning has recently become a key computational tool for the analysis and understanding of scientific data. This talk describes our efforts in providing state of the art techniques in data analysis by doing research that lies at the intersection of machine learning, statistics, data mining, physics and astronomy. The talk discusses two projects. The first is on the development of an efficient pattern recognition tool for the automated identification and classification of tracks of ionizing radiation as measured by a pixel detector system. Such software has many applications including dosimeters to assess the risk of human exposure to radiation, and area monitors to characterize the general background radiation environment harmful to humans and electronic equipment. The second application is on the automatic geomorphic mapping of planet Mars; the goal is to divide a landscape (represented by an image, digital elevation model DEM, or other spatial datasets) into a set of landscape elements having specific surface patterns. These elements are later grouped into a set of clear landforms (e.g., craters, valleys, ridges, etc.).
