  • Publication number: 20240152788
    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.

  • Patent number: 10991071
    Abstract: An information processing apparatus includes a partial image generator configured to generate a partial image having a point-of-interest designated by a user, from a 360-degree image, a user interface (UI) unit configured to receive an indication of the point-of-interest via a UI screen for displaying the partial image, and a point-of-interest registering unit configured to register the point-of-interest, in response to a request from the user via the UI screen. The information processing apparatus also includes an interpolation line calculator configured to calculate an interpolation line for interpolating between a most recently registered point-of-interest and a current point-of-interest, and an interpolation line registering unit configured to register an interpolation line between the designated point-of-interest and a point-of-interest designated immediately prior to the designated point-of-interest.

  • Patent number: 10350712
    Abstract: A solder paste whereby metal does not flow out of a joint during a second or subsequent reflow heating stage. The solder paste exhibits high joint strength at room temperature and at high temperatures, excels in terms of temporal stability, exhibits minimal void formation, and can form highly cohesive joints. The solder paste comprises a powdered metal component and a flux component, the powdered metal component comprising: a powdered intermetallic compound that comprises copper and tin and has metal barrier layers covering the surfaces thereof and a solder powder including tin as a main component. Neither the powdered intermetallic compound nor the solder powder contains a copper-only phase, inhibiting the elution of copper ions into the flux.
