    The Machine Learning and Optimization Group is supported by the POC 2014-2020 grant - ANCSI Competitiveness Operational Programme 2014-2020. Project name: DeepRiemann - Riemannian Optimization Methods for Deep Learning (2016-20) (~1.9M EUR) Principal Investigator Dr. Luigi Malagò

    The DeepRiemann project aims at the design and analysis of novel training algorithms for Neural Networks in Deep Learning, by applying notions of Riemannian optimization and differential geometry. The task of the training a Neural Network is studied by employing tools from Optimization over Manifolds and Information Geometry, by casting the learning process to an optimization problem defined over a statistical manifold, i.e., a set of probability distributions. The project is highly interdisciplinary, with competences spanning from Machine Learning to Optimization, Deep Learning, Statistics, and Differential Geometry. The objectives of the project are multiple and include both theoretical and applied research, together with industrial activities oriented to transfer knowledge, from the institute to a startup or spin-off of the research group.

    # How to reach us

    The office is located in the city center of Cluj, only 9km away from the Cluj International Airport (Aeroportul International Avram Iancu Cluj). The simplest way to reach our office from the airport is to take a Taxi (around 25 lei). Alternatively, you can take the buses n. 5 or 8 in front of the airport, both stop at less than 10 minutes by walk from the office (ticket 2 lei). More information about the location of the bus stops can be found using Google Maps.
