The next meeting of the Operations Research Seminar will be held on July 2nd (Tuesday) at 2:00 pm in Room 503 of IMI - BAS. A talk on On some contemporary mathematical methods for data analysis will be held by Prof. Pando Georgiev, IMI - BAS. Abstract: We will review some selected methods and algorithms for data analysis: A) Latent component analysis - reveals hidden features of composite data. Particularly, we will describe some     Signal Separation Methods: based on statistical independence - Independent Component Analysis based on sparsity. - Sparse Component Analysis based on non-negativity - Non-Negative Matrix and Tensor Factorization B) New approach to multiclass learning problems and applications to some problems in machine learning, as: nonlinear least square problems subspace [...]
