A generation device executes an inference process of inputting analysis target data to a plurality of inference models and outputting a plurality of inference results related to an object included in the analysis target data from the plurality of inference models, a determination process of determining, based on the plurality of inference results, a specific inference result from the plurality of inference results output by the inference process, and a generation process of generating a training data set including the specific inference result determined by the determination process and the analysis target data.

Data analysis and training data, generation device, system, method, and generation program

An apparatus is describe for detecting a shape of an object to be recognized from to-be-analyzed data; generating one or more components and respective contribution ratios of the components through a component analysis, based on the shape of the object to be recognized; determining an ordinal number indicating each dimension of the components based on a cumulative contribution ratio attained from the respective contribution ratios; selecting, among the group of action classification models, a specific action classification model in which learning was performed with the same component group as a specific component group including the components with the ordinal number indicating the dimension; and inputting the specific component group into the specific action classification model, thereby outputting recognition results indicating actions of the object to be recognized.

Provided is a light information device, and the like, that records header information on an information recording medium, after preventing screen burn of a spatial light modulator. One example of the solution in the present invention is a light information device that records two-dimensional page data on an information recording medium and is provided with a first information generation unit, a second information generation unit that generates a second bit string on the basis of a first bit string, and a spatial light modulation unit that displays a pattern corresponding to the second bit string. The second information generation unit: performs a first processing, on the first bit string corresponding to first identification information, that inverts each bit at a prescribed cycle; generates the second bit string corresponding to the first identification information; performs a second processing, different from the first processing, on the first bit string corresponding to second identification information that includes bits which are switched at the same cycle as the prescribed cycle; and generates the second bit string corresponding to the second identification information.

Light information device and light information processing method

An optical-information recording/reproducing apparatus of the present invention is capable of carrying out position detection of a reproduction image even if reproduction image data with incomplete alignment marks (markers) is obtained. A relative correlation value is calculated from a first correlation value retained by a first correlation-value retaining unit and a second correlation value retained by a second correlation-value retaining unit, and pass/fail of a position detection result of the marker is judged according to the relative correlation value. The pass/fail of the position detection result is judged by mutually comparing the detection positions of the markers judged as passes by the relative correlation-value judgement, the positions of the markers judged as fail by the relative correlation-value judgement or the mutual position judgement is complemented, and the position of two-dimensional data is detected based on the pass-judged markers and the complemented markers.

An optical information recording apparatus configured to record information into an information recording medium by using holography, the apparatus including: a signal generation unit configured to generate two-dimensional data; and a two-dimensional spatial light modulator unit configured to display the two-dimensional data and to spatially modulate a transmitted or reflected beam, wherein the two-dimensional spatial light modulator unit includes a signal region and an external region, the signal region displays two-dimensional data based on user data, the external region displays two-dimensional data not including the user data, and the signal generation unit generates two-dimensional data in such a manner that a frequency of the two-dimensional data displayed on the external region becomes equal to or larger than a frequency of the two-dimensional data displayed on the signal region.

Optical information recording apparatus and optical information recording method

An information recording/reproducing device capable of recording or reproducing information to or from a plurality of information recording media, includes a plurality of information recording/reproduction drives which can record or reproduce the information recording media and during recording or reproduction, can measure information recording medium quality evaluation item values representing values indicative of qualities of the information recording media; and an information recording medium monitor which can calculate tendency to quality degradation of the information recording medium from information recording medium quality evaluation item values preserved by an information recording medium monitoring database which can preserve the measured information recording medium quality evaluation item values. The information recording medium monitor is capable of calculating from a tendency to quality degradation of an arbitrary information recording medium the quality of another information recording medium.
