摘要：Problem to be solved: to provide a learning apparatus and a learning methodcapable of forming a histogram about the feature amount and gradient informationinputted in parallel, and capable of reducing the circuit scale of the memory which holdsthe information of the histogram. In a learning device for learning by gradient
boostingLearning data including featuresA plurality of data storage units for storinggradient information andA plurality of data storage units are provided corresponding tothe respective data storage sections.Data storage sectionEnter the gradient informationandFrom the output port corresponding to each input valueA gradient output sectionwhich outputs gradient information corresponding to a feature quantity andThe gradientinformation corresponding to the value of the same feature output from each gradientoutput part is added.An adder that outputs the added value of gradient informationcorresponding to each value andThe added value of the gradient informationcorresponding to each value of the feature quantity output from the added valueAhistogram storage unit for storing histogram multiplied by each bin when each value is abottle and.Diagram
