- Training of the neuronal net can be started
for the current posting date, using the latest run of data feed for the underlying data marts. For each training iteration, a test against the training group is performed. The test compares the prediction made on the basis of the training portfolio with the real figure in the test portfolio.
The graph below shows the training process: For the training of neuronal networks, the portfolio will be split into two groups of deals:- Training
- Testing
Figure: Model score versus iteration
- Influence of individual attributes (weight in %) can be viewed
as result of the training of the neuronal network. It can be seen which parameters and which weighting have been included in the ECL calculation for the entire portfolio of assets.
