Deformable 3D Shape Matching with Topological Noise

This dataset consists of a collection of 3D shapes undergoing within-class deformations that include in topological changes. The changes simulate coalescence of spatially close surface regions – a scenario that frequently occurs when dealing with real data under suboptimal acquisition conditions. The dataset is based on the fat kid from the KIDS dataset with additional poses. All shapes are given in OFF format and exist in two different resolutions (~10k and ~60-80k).

Ground-truth matches to the null shape are given for all shapes, but due to the changes in topology not all vertices have a ground-truth match. A map indicating which vertices do not have a match is provided. We also provide a ground-truth symmetry correspondence for all shapes.

French-German Machine Learning Symposium

French-German Machine Learning Symposium

The French-German Machine Learning Symposium aims to strengthen interactions and inspire collaborations between both countries. We invited some of the leading ML researchers from France and Germany to this two-day symposium to give a glimpse into their research, and engage in discussions on the future of machine learning and how to strengthen research collaborations in ML between France and Germany.

The list of speakers includes Yann LeCun, Cordelia Schmid, Jean-Bernard Lasserre, Bernhard Schölkopf, and many more! For the full program please visit the webpage.
