Website: https://sites.google.com/view/maclean2020/ Workshop colocated with ECML/PKDD 2020 KEY DATES - Extension Paper submission deadline: July 9th, 2020 Paper acceptance notification: August 2nd, 2020 Paper camera-ready deadline: TBA Workshop date: September 14 or September 18 (TBA) CONTEXT The huge amount of data currently produced by modern Earth Observation (EO) missions has raised up new challenges for the Remote Sensing communities. EO sen- sors are now able to offer (very) high spatial resolution images with revisit time frequencies never achieved before considering different kind of signals, e.g., multi- (hyper)spectral optical, radar, LiDAR and Digital Surface Models. In addition, con- sidering successive acquisitions of satellite imagery over the same area, it is also possible to organize these data as satellite image time series (SITS), in order to track and monitor phenomena over time. In this context, modern machine learning techniques can play a crucial role to deal with such amount of heterogeneous, multi-scale and multi-modal data. Some examples of techniques that are gaining attention in this domain include deep learn- ing, domain adaptation, semi-supervised approach, time series analysis and active learning. Leveraging Machine Learning approaches for the analysis of EO data can be beneficial (or even crucial) for several EO-related tasks such as precision agri- culture and food risk prevention, mapping biodiversity, monitoring climate changes, understanding temporal trajectories related to the evolution of natural habitats and generally, manage resources in a territory and provide more accurate information on environmental and anthropic phenomena. Even though the use of machine learning and the development of ad-hoc techniques are gaining increasing popularity in the EO domain, we can witness that a significant lack of interaction between domain experts and machine learning re- searchers still exists. People coming from these two different communities, currently, may often have some difficulties in structuring themselves around these issues due to a lack of mutual knowledge. The objective of this workshop is to supply an international forum where machine learning researchers and domain-experts can meet each other, in order to exchange, debate and draw short and long term research objectives around the exploitation and analysis of EO data via Machine Learning techniques. Among the workshop’s objec- tives, we want to give an overview of the current machine learning researches dealing with EO data, and, on the other hand, we want to stimulate concrete discussions to pave the way to new machine learning frameworks especially tailored to deal with such data.
