Borovikov I.A. Approximate categories and approximate decomposition
//Modern group analysis. MIPT.1993,pp.21-24 (In Russian)
Introduced a notion of category with approximate morphisms. Approximate decomposition is defined as morphism in such category. |

Borovikov I.A. Maximum Principle and backpropagation// Neurocomputer,
Vol. 3,4; 1992, Moscow, p. 21-24 (in Russian)
Derived backpropagation equations from maximum principal. Introduced a new class of "symmetric" neural networks with learning cycle twice faster than classical. |

Borovikov I.A. Groups of symmetries and decomposition of neural
network models of reflexion//Proc. of International seminar "Modern
group analysis", Ufa, Institute of Mathematics and Computer Center,
1991. (in Russian) p.11
Reflexion is studied in a neural networks models using methods of group analysis. Group invariants of the model are treated in terms of reflexive behavior. |

Borovikov I.A. Choice
of decomposition structure in optimal control, Ph.D. dissertation,
MIPT, 1989, 140 p. (in Russian)
Detailed discussion with proofs and examples of results published in some of the previous papers. In addition, new numerical method of decomposition in optimal control is discussed. |

dynamic systems theory//Kibernetika i vichislit.tehnika (Cybernetics and
computing technology), Kiev, 1989, Vol. 81, p. 18-23 (in Russian)
Defined almost controllability for affine systems. Criterion of almost controllability and its connections to weak controllability and controllability were obtained using non-standard analysis and differential geometry. |

controllability //Modelirovanie processov upravlenia i obrabotki
