Opis:: A mathematical model of architecture and learning processes of multilayer artificial neural netwoks is discussed in the paper. Dynamical systems theory is used to describe the learning precess of networks consisting of linear, weakly nonlinear and nonlinear neurons. Conjugacy between a gradient dynamical system with a constant time step and a cascade generated by its Euler method theorem is applied as well.

Tytuł:: A neural system of phonematic transformation

Bielecki, A.
Powiązania:: https://bibliotekanauki.pl/articles/1931576.pdf
Data publikacji:: 2003
Wydawca:: Politechnika Gdańska
Tematy:: neural networks
input-output data representation
phonematic transformation
Opis:: A common task in speech processing for which neural networks are widely employed is text-to-phoneme conversion. In this paper we propose a novel solution to this problem by combining a multilayer neural network and a modular hybrid system that uses basic rules to subdivide the original problem into easier tasks which are then solved by dedicated neural networks. A hybrid solution can be more rapidly constructed than a single net solution, and is easily extendable. Input data representation is also discussed. A voting committee concept is used to enhance generalization abilities of the system. Efficiency of the proposed systems is compared.

Opis:: The paper presents an idea and analysis of application of a new solution of a stage before extraction in the modernised LP part of 200MW turbines with ND exhaust. The idea of the patent is to introduce to the turbine steam path a ring directing high energy tip leakage steam from the stage to the regenerative extraction. Owing to this it is possible to cheaply achieve some energy benefits from the operation of first heat exchanger which in the modernised 200MW turbine is continuously underheated. Ring design has been checked using CFD and CSD numerical codes.
