22nd Mathematics Webinar
AI Mathematics: Advanced Neural Networks Approximation
In this webinar our two main features are as follows:
We will present the new idea of moving from the main neural network tools, the activation functions, to convolution integrals and singular integrals approximations. That is, the rare case of employing applied mathematics to treat theoretical ones.
We will introduce and also use the symmetrized neural network operators able to achieve supersonic speeds of convergence.
We will use a great variety of activation functions. Thus this webinar will present the original work by the speakers given at a very general level to cover a maximum number of different kinds of neural networks, covering ordinary, fractional and stochastic approximations. Univariate, fractional and multivariate approximations will also be presented. Iterated-sequential multi-layer approximations will be discussed as well.
