Machine Learning for Big Data Analysis

2.Relative to the median to make the centring procedure of the robust properties (protection against abnormal observations) by the recurrent equation

$m{e}_i\left(k\right)=m{e}_i\left(k-1\right)+{\eta }_m\text{sign}\left(x_i\left(k\right)-m{e}_i\left(k-1\right)\right),i=1,2,\dots ,n,\left(5.18\right)$

where ηm is the parameter of the search step selected in accordance with the conditions of stochastic approximation of Dvoretzky [26].

Step 2: Initialization of initial state of neural network

Initialization of the initial state of the neural network is a self-adaptive deployment of network neurons with the formation of an ordered self-organizing Kohonen map. The main idea of this method is described in [23] and consists in the gradual retraction of inactive ...
