Machine Learning for Remote Sensing Data Analysis
Speaker: Dr. Gustau Camps-Valls

Machine learning has become a standard paradigm for the analysis of remote sensing and geoscience data at both local and global scales. In the upcoming years, with the advent of new satellite constellations, machine learning will have a fundamental role in processing large and heterogeneous data sources. Machine learning will move from mere statistical data processing to actual learning, understanding, and knowledge extraction. The ambitious goal is to provide responses to the challenging scientific questions about the Earth system.

The current lecture shall be focused on remote sensing image processing chain, and take the attendants on a tour of different strategies for feature extraction, classification, unmixing, retrieval, and pattern analysis for remote sensing data analysis. Powerful methodologies for remote sensing supervised remote sensing data classification shall be discussed: extracting knowledge from data, including interactive approaches via active learning, classifiers that encode prior knowledge and invariances, semi supervised learning that exploit the information of unlabelled data, and domain adaptation to compensate for shifts in the ever-changing data distributions.
