{insert research topic here} Data Challenge Carlos Alberto Gomez Gonzalez
Global Challenges Science Week. June3, 2019
Exoplanet Imaging Data Challenge Planet: a celestial body moving in
an elliptical orbit round the Sun
Exo from extrasolar (outside of the Solar System)
Exoplanet Imaging Data Challenge
Data challenges • Problem to solve • Benchmark data •
Metrics • Platform for hosting the competition • Motivate people to participate (*)

exoplanet Stars never shut off !!!
Debris disk Beta Pictoris (occulted)
Yep, this is the exoplanet (Beta Pictoris b)
4k confirmed exoplanets but only ~1% observed!

Fake planet (low contrast) Signal and noise
spatially rescaled images t0 t0 with an integral field spectrograph
Signal and noise
Image processing pipeline Getting rid of the noise…
Algorithms 2006 - 2019 • Median frame subtraction • Pairwise
subtraction (GRAPHIC) • Least squares image combination (LOCI) • Low-rank approximations (PCA, NMF) • Low-rank plus sparse decompositions (LLSG) • MLE & Matched filtering (ANDROMEDA, KLIP-FM) • Supervised detection with deep neural networks (SODINN)
None
None
Data • Lack of benchmark data in the HCI community
• Requested datasets from the most important HCI instruments on Earth • Heterogeneous in terms of quality and characteristics • Synthetic companions were injected
None
Submissions
Blob counting
Metrics
None
