  • Patent number: 9311729
    Abstract: An information processing apparatus that tests independence among a multiplicity of variables includes an execution section and a determination section. The execution section executes a test for conditional independence between two variables in a graphical model that are at least not independent in the case where a condition variable serving as a condition for independence between the two variables is provided on a path between the two variables. The determination section determines whether or not a V-shaped structure is present on a path between the two variables, the V-shaped structure being a graph structure in which first and second variables that are independent are each not independent of a third variable. The execution section does not execute a test for conditional independence between the two variables in the case where the condition variable is provided only on a path determined to have the V-shaped structure.

  • Patent number: 8983892
    Abstract: A probability function with highest likelihood is calculated based on data. A canonical distribution in statistical physics and a temperature parameter of the canonical distribution are calculated as a fluctuation of the data. A probability function is estimated using the calculated probability function with the highest likelihood, the calculated fluctuation, and the canonical distribution. The present technology is applicable to an apparatus that estimates and uses a probability function.

  • Patent number: 8532401
    Abstract: An image processing apparatus includes a dividing unit, a first extracting unit, a quantizing unit, a generating unit and an image output unit. The dividing unit divides an object image into regions. The first extracting unit extracts image features of the regions generated by the dividing unit. The quantizing unit quantizes the image features extracted by the first extracting unit. The generating unit generates an expected value of an occurrence probability of each topic variable indicating similar images from the image features quantized by the quantizing unit, using a correlation between the image features quantized by the quantizing unit and the topic variables. The image output unit outputs an image of a defective portion in the object image, using the expected values of the occurrence probabilities of the topic variables generated by the generating unit.
