Machine learning device, learned model, data structure, periodontal disease inspection method, periodontal disease inspection system, and periodontal disease inspection kit

摘要

A machine learning device for learning a probability of periodontal disease or a function for judging a state of periodontal disease, wherein intraoral information detected from a sample and a periodontal disease probability of a provider of the sample are provided. Or at least one judgment value selected from the group consisting of periodontal disease states; and a learning unit for learning the function for determining the judgment value, based on a plurality of learning data, the learning unit comprising: Based on the learning data, a reward calculating unit that calculates the probability of periodontal disease or the result of determining the state of periodontal disease using the function, a reward calculated by the reward calculating unit, Machine learning including a function updating unit that updates the function so as to be higher, and a convergence determining unit that repeats the calculation by the reward calculating unit and the updating by the function updating unit until a predetermined convergence condition is satisfied. apparatus.
