com.github.neuralnetworks.calculation.LayerCalculatorImpl
Implementation of the LayerCalculator interface for calculating single target layer It takes advantage of the fact that the neural network is a graph with layers as nodes and connections between layers as links of the graph The results are propagated within the graph
