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 clustering and non-linear skeletons
- reconstruction of several functions from mixed samples
- support vector kernel regression (under development)
C) kernel methods for data analysis
D) tensor decompositions and tensor networks.
Some of the above topics are interconnected and subject to intensive development with numerous applications.
