Learning apparatus, learning method, program, trained model, and endoscope system

Abstract

There are provided a learning apparatus, a learning method, a program, a trained model, and an endoscope system that can perform efficient learning even when the learning is performed using pieces of data acquired under conditions different from each other. A learning apparatus includes a hierarchical network including a first input layer, a second input layer, a first intermediate layer, a first normalization layer, a second normalization layer, a second intermediate layer, and an output layer. A learning control unit of the learning apparatus causes first learning and second learning to be performed. In the first learning, a to-be-trained model is trained based on a first error between a first recognition result and a correct answer for first data. In the second learning, the to-be-trained model is trained based on a second error between a second recognition result and a correct answer for second data.
