Abstract: The present technology relates to an information processing system, an information processing method, and a program that make it possible to determine execution of learning, without relying on external instruction inputs. The information processing system determines an action on the basis of environmental information and a learning model obtained through learning based on an evaluation function for evaluating an action.

Abstract: The present disclosure relates to an information processing system, an information processing method, and an information processing device that make it possible to perform learning adaptively to changes in an external environment and circumstances. A learning section learns results of action selection made by a system in response to input information. An input information assessment section assesses a risk of the input information to the system. A first parameter calculation section calculates a first parameter representing stress on the system according to an assessed value of the input information. The learning section changes learning efficiency according to the first parameter. The technology according to the present disclosure is applicable, for example, to an information processing system that performs machine learning.

Abstract: The present technology relates to an information processing system, an information processing method, and a program that are capable of facilitating the understanding of an explanation regarding AI processing. The information processing system includes an evaluation portion that evaluates multiple choices according to two or more evaluation criteria based on parameters obtained during a process or a result of machine learning, and an explanation portion that generates explanatory text regarding each of the choices by using a phrase associated with a corresponding one of the evaluation criteria. For example, the present technology is applicable to hardware and software performing various processes with the use of AI.

Abstract: In a method for roll forming a flat metal strip through a roll forming machine into a round tubular product while the metal strip is being lengthwise fed therethrough, an improved method wherein regions of a specified width extending inward from the edges of said strip are imparted with substantially zero curvature. The tube forming method prevents decrease in the wall thicknesses at the edges when used in the manufacture of a thick walled electric welded pipe, and prevents the occurrence of edge buckling and springback when used in the manufacture of thick walled pipe so that in either case a proper and satisfactory butt junction for subsequent welding can be obtained.
