На 2-ри юли (вторник) от 14:00 ч. в зала 503 на ИМИ ще се състои сбирка на Семинара по Изследване на операциите. Доклад на тема On some contemporary mathematical methods for data analysis ще изнесе проф. Пандо Георгиев, ИМИ-БАН. Абстракт: 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 [...]
На 1 октомври (вторник) от 14:00 ч. в зала 503 на ИМИ ще се състои сбирка на Семинара по Изследване на операциите. Доклад на тема Graphs as an universal modeling tool ще изнесе проф. Никола Янев, ИМИ-БАН. Абстракт: For a series of practical optimization problems, we show that formulating them as graph optimization problems enables the development of competitive algorithms. The problems considered are known as: protein threading problem, contact map overlap, HP folding, a new scheduling theory problem, classification problem and the biclustering problem. The focus is on formulating them as graph optimization problems, which are solved by using Integer programming techniques.

На 15 октомври (вторник) от 14:00 ч. в зала 503 на ИМИ ще се състои сбирка на Семинара по Изследване на операциите. Доклад на тема Asymptotic covariance matrix of Capon’s Maximum likelihood estimator and application of steered response power phase alignment algorithm in seismic array data processing ще изнесе Александр Варипаев от секция ИОСВ. Абстракт: Capon’s estimator was originally developed for frequency-wavenumber power spectral density analysis. Theoretically, it can be treated as maximum likelihood estimator of unknown vector parameter of multidimensional linear system (MLS) model with one input and m outputs. Practically important and non-trivial case is considered, when the number of nuisance parameters, which are values of input deterministic signal, tends to infinity. Under assumptions that MLS output signals distorted by random Gaussian stationary [...]
