MODEL IMPROVEMENT SYSTEM AND MODEL IMPROVEMENT METHOD

To efficiently and appropriately improve an inference model when the inference model outputs an inappropriate inference result that affects work. A model improvement system performs inference related to the work using an inference model which is a machine learning model that outputs an inference result by inputting an input matrix, acquires an actual result which is information acquired by actually performing work to be inferred by the inference model, determines whether or not the inference result is an inappropriate content that affects the work by comparing the inference result with the actual result, divides a part of the input matrix that outputs the inference result that affects the work from the input matrix, and generates an inference model that outputs an inference result that does not affect the work when the part divided from the input matrix is input as an input matrix.
