ENSEMBLE

Keyword of Integer Type

This keyword indicate number of network in ensemble that will be analyzed. This allows to estimate variance of neural network predictions for the whole data set  and for each data entry.

The result of  calculation is simple average of all networks. The program also estimates variance of RMSE of all networks in the ensemble. It recalculates neural networks with RMSE error that is higher than 3 standard deviations from the average RMSE.

We recommend to use ENSEMBLE of 100-400 neural networks. A smaller number provides a high error of neural network results, while a larger number requires too long calculations.

The range of this keyword is [1,10000] and default value is {200}.
