NeuralNetwork and CL

ROOT
1

Hi

I would like to ask, if there is a ROOT function combining NeuralNetwork output (like TMultiLayerPerceptron) with obtaining CLs.

Thanks in advance

Hi,

I am not sure I have understood your question correctly. What do you mean by combining neural network outputs ? Do you want to estimate a confidence interval from an analysis using neural networks ?
The neural network is typically used to select your data sample which can then be used for estimating an interval or an upper limit. Using the neural network and estimating the interval are two separate steps of the analysis.
In ROOT, in particular in the HistFactory of RooStats we have tools for building combined models from counting data or from histograms, which could be used to represent the output of the neural network.
