An action learning system includes a memory, and a processor configured to train, based on first data indicating a property of an environment in which data is collected from multiple devices and to which an action determined by a first neural network according to a state of the environment is applied and second data indicating a property of the environment to which the action is not applied, a second neural network that calculates a similarity degree between distributions of the first data and the second data, and train, after the second neural network is trained, the first neural network that determines an action according to the state of the environment, by reinforcement learning including, in a reward, a value that changes based on a relationship between a similarity degree and a parameter set by a user, the similarity degree being calculated by the second neural network based.

Behavior learning system, behavior learning method and program

A program execution system includes a data holding apparatus, a program providing apparatus, and a data processing apparatus that performs computing in a secure region. The data holding apparatus transmits encrypted data, encrypted with a first common key, to the data processing apparatus, and the program providing apparatus transmits an encrypted program, encrypted with a second common key, to the data processing apparatus. In the secure region, the data processing apparatus acquires data by decrypting the encrypted data with the first common key, acquires a program by decrypting the encrypted program with the second common key, executes the program for the data, and encrypts a result of the execution with a public key of the data holding apparatus or the first common key. The data holding apparatus acquires the result of the execution by decrypting the encrypted result of the execution with a secret key or the first common key.
