TOWARDS A BIOSPHERE ATMOSPHERE CHANGE INDEX

WP5 Synthetic Index and Attribution Scheme: the BACIndex

Lead: FSU Jena
Main Contact: Joachim Denzler
Team: Marcel Simon, Yanira Guanche, Joachim Denzler (WP5 lead)

OBJECTIVES

The goal of WP5 is the development of a synthetic change or novelty index (BACIndex) that allows for detecting sudden events and abnormal changes in the multivariate EO data streams. The index will be generic, but in the context of the project, specific emphasis will be on detecting abrupt changes that are relevant to the essential ecosystem variables, i.e. properties relevant to the functioning of terrestrial ecosystems, biosphere-atmosphere exchanges of matter and energy, and biodiversity related properties. The problem of detecting change in given data is a challenging machine learning problem and is often referred to as “novelty detection” or “discovery”. WP5 also entails an attribution scheme, i.e. machine learning techniques that allow for measuring the influence of input variables on the novelty detection score.
