A key challenge in cosmological research is how to extract the most important information from satellite imagery and radio signals. The difficulty lies in the systematic processing of extremely noisy data for studying how stars and galaxies evolve through time. This is critical for astrophysicists in their effort to gain insights into cosmological processes such as the characterisation of dark matter in the Universe. Helping scientists find their way through this data maze is DEDALE, an interdisciplinary project that intends to develop the next generation of data analysis methods for the new era of big data in astrophysics and compressed sensing.
for learning a complicated manifold (the spiral shell). The DEDALE team are investigating ways to use machine learning techniques to find new representations for big data sets and in some cases to learn the manifold (i.e. the geometrical space like the surface of the Earth or a cube) on which the data lies.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
