Medical information processing apparatus and medical information processing system

A medical information processing system comprising information processing apparatuses respectively provided in a plurality of medical institutions and a medical information processing apparatus capable of communicating with each of the information processing apparatuses, wherein

• the medical information processing apparatus includes a processing circuitry configured:
• to distribute, to each of the information processing apparatuses, a program for causing a machine learning process to be executed by using medical data held at the medical institution having the information processing apparatus;
• to receive, from each of the information processing apparatuses, a change amount in a parameter related to the machine learning process, regarding a change caused in conjunction with the execution of the machine learning process;
• to adjust a value of the parameter on a basis of the received change amount;
• and
• to transmit the adjusted parameter to each of the information processing apparatuses to cause the machine learning process to be executed on a basis of the parameter.
