Dr. Artiom Kovnatsky

A single data scientist working on novel strategic products of HOMEDAY: • HOMEstimate: automatic valuation of properties • HOMEtrend: property price trends in Germany • HOMEDAY-PREISATLAS: based on HOMEtrend and HOMEstimate; in media: handelsblatt.com, welt.de, focus.de, berliner-zeitung.de, bild.de, stern.de, etc • Built a model for lead conversion • Performed financial analysis: estimated confidence intervals of ROI as the function of time

Research group supervised by Prof. Michael M. Bronstein. • Mathematical formulation/modelling, implementation, testing/validation • Problems from Machine Learning, Computer Vision, Computer Graphics and Image Processing fields: correspondence problems, manifold non-smooth optimization, dimensionality reduction, multi-modal clustering, spectral methods, matrix factorization/completion, image color manipulation • Publications in top journals/conferences • Used mostly Matlab, occasionally Python and R

Worked on “Controllable dynamic range expansion and inpainting of bright visual data for HDR displays”. • Researched image/video inpaiting and high dynamic range imaging • Initiated several new research directions • Technicolor submitted a patent (got a job offer) Used Matlab, C/C++ (MEX), OpenCV

Computer Vision, Manifold/Machine Learning, Optimization
