Issue and perspectives

Artificial intelligence is at the heart of technological, scientific, economic, societal and environmental transformations. In this context, data modeling for description, decision, prediction and/or forecasting purposes becomes an essential issue. Our workgroup is dedicated to this issue and brings together methodological works dealing with machine learning (deep learning, data mining), the fusion of uncertain data (probabilities, possibilities, belief functions, fuzzy sets, intervals) and signal processing (wavelets, statistical learning, differential geometry). These works are mainly applied to/triggered by the analysis of remote sensing data with a temporal dimension; most often for environmental monitoring purposes (crustal deformation, erosion, deforestation, glacial retreat, marine pollution). Remote sensing work is also being carried out to produce such data, with the main objectives of measuring displacements, detecting changes and inverting models. Our scientific perspectives are multiple and concern 1) the consideration of the volume, uncertainty and complexity (spatial, temporal, physical properties) of data, 2) the fusion of data and/or models, and 3) the interpretability of the obtained results.

Keywords: deep learning, data mining, data fusion, uncertainties, remote sensing, time series, environmental monitoring.
