An approach to synthesis of a phonetically representative english text of minimal length

Autor: Natalia Bloshchynska, Natalia O. Myronova, Nataliya Keberle, Hennadii Dobrovolskyi

Publikováno v: 2018 14th International Conference on Advanced Trends in Radioelecrtronics, Telecommunications and Computer Engineering (TCSET).

To assess foreign language pronunciation one must listen to a speaker, which is a very time consuming task. To reduce the efforts it is proposed to construct a text of minimal length preserving English corpus natural phoneme distribution. Such a text

Sparse symmetric nonnegative matrix factorization applied to face recognition

Autor: Hennadii Dobrovolskyi, Nataliya Keberle, Yehor Ternovyy

Publikováno v: IDAACS

The task of Sparse Symmetric Nonnegative Matrix Factorization(SSNMF) is formulated as optimization problem and solved numerically with the method of projected gradients descent. The adjustable sparsity level allows to emphasize the most significant o
