-Our main research areas include+For a brief description of our main research areas, we mention
  
   * **Machine learning**: We address several ​ aspects of machine learning, from the design of kernel methods to manifold learning and deep learning. Current research include modeling and simulation of spatio-temporal variations and dynamics using manifolds, understanding of the GANs approaches and their link to Optimal Transport, Siamese network for multimodal learning and autoencoders or solving multiclass SVM at the cost of a binary one, and dealing with indefinite kernels or large datasets.   * **Machine learning**: We address several ​ aspects of machine learning, from the design of kernel methods to manifold learning and deep learning.

   * **Computational geometry**: We design algorithms and data structures for numerous geometric problems related to range searching, geometric graphs, and several other topics. We analyze that asymptotic complexity of these algorithms and also prove lower bounds for the complexity of the problems.   * **Computational geometry**: We design algorithms and data structures for numerous geometric problems related to range searching, geometric graphs, and several other topics.
