The Great-3 challenge is now complete and the winners decided. We have also now deactivated the post-challenge leaderboards, so no more submissions can be made at all.
|Name||Notes||Score||Number of entries|
|Amalgam@IAP||Some fellows developing software based around SExtractor and PSFex for real-life shape measurements.||80000||215||BAMPenn||Bernstein, Armstrong & March, University of Pennsylvania.||0||8||CEA-EPFL||The team wants to investigate if we could improve shear estimation by combining gfit with sparse representation methods.||72000||340||CEA_denoise||Moment correction on denoised images.||0||25||CMU experimenters||This is a team for Rachel Mandelbaum's group at CMU to experiment with some crazy ideas that probably won't work, but are kind of fun to think about.||*||4||COGS||Capitalizing On Gravitational Shear Team based primarily at University of Manchester and University College London, and lead by Sarah Bridle. Most entries will use the im3shape code described in http://arxiv.org/abs/1302.0183.||*||38||DeepZot||Team members: Daniel Margala and David Kirkby at UC Irvine||0||0||E-HOLICs||E-HOLICs method is developed for aim of precise and fast shear analysis. E-HOLICs method is moment method like KSB method , but use elliptical weight function for avoiding one of systematic errors.||3000||58||EPFL_HNN||Hopfield Neural Network||0||32||EPFL_KSB||From quadrupole moments to shear, based on the KSBf90 (Heyamans et al. 2005).||0||39||EPFL_MLP||MLP||0||51||EPFL_MLP_FIT||multilayer perceptron, fitted data as input||0||1||EPFL_gfit||Using the gfit shear measurement method, testing how far one can go by using forward model fitting + new approaches for bias calibration||24000||124||EPFL_lensfit||Testing a multi-processor version of lensfit 7.2 (Miller et al., 2007, Kitching et al., 2008)||0||0||FDNT||Fourier Domain Null Test method (Bernstein 2010) with additional m+c bias calibration||*||36||Fourier_Quad||Our team uses the quadrupole moments of the spectral density of galaxy images in Fourier space to measure shear.||32000||36||GREAT3_EC||GREAT3 executive committee - submissions using example scripts.||*||10||HSC/LSST-HSM||A sanity check of the bookkeeping in the obs_great3 package written to allow HSC/LSST pipeline algorithms to be run on the GREAT3 simulations, using an old implementation of the HSM code.||*||4||MBI||Team members:Lang CMU, Hogg NYU, Schneider LLNL, Dawson LLNL, Bard SLAC, Marshall SLAC, Meyers Stanford, Boutigny SLAC||1000||51||MaltaOx||Malta-Oxford GREAT3 team. We aim to test shear measurement by likelihood fits to individual galaxies, using lensfit, and without using simulations to calibrate bias.||3001||15||MegaLUT||Evolutions of the MegaLUT technique : how far can we go with SExtractor + Machine Learning ?||52000||234||MetaCalibration||This team is testing how well we can extract the shear response by shearing the images themselves, and modifying the psf accordingly.||*||3||Wentao Luo||A modified method based on both BJ02(Bernstein & Jarvis 2002) and HS03(Hirata & Seljak 2003).||0||25||ess||Various pipelines by Erin S. Sheldon||0||13||miyatake-test||Test for GREAT3 data by the HSC pipeline.||*||4||sFIT||Modified DLS stackfit algorithm||80001||162|
