To provide a method and a device for pain estimation capable of objectively and accurately discriminating pain of an estimation object.SOLUTION: There is provided a method and a device for estimating pain capable of objectively and accurately discriminating pain of an estimation object. In more detail, there are provided a pain monitoring method for monitoring pain of the estimation object based on a brain wave of the estimation object, and a device and a system for executing it. There are also provided a method for generating a model to discriminate the object pain, and a device and a system for executing it. There are further provided a machine learning improvement method, and a device and a system for executing it. There are further provided a method for determining pain by using a brain feature amount including at least one of brain wave feature amounts such as brain wave feature amount interrelation and a complexity index, and a system and a device for executing it in order to provide accurate pain discrimination efficiently.SELECTED DRAWING: None
