  • Patent number: 11657077
    Abstract: A computer system document according to one embodiment includes a generation unit and an update unit. The generation unit performs first machine learning on a target document, as input data, to which a correct path in a tree structure where each node indicates a document category is given, and thereby generates a classification model indicating a right path to a leaf node for the target document. The update unit performs second machine learning that applies, to the classification model, the target document to which the correct path is not given, and when a path from an Nth level node to an (N+1)th level node is different from the correct path, updates the classification model by setting a modified path from the (N+1)th level node to an (N+2)th level node different from a child node of the (N+1)th level node based on the correct path.

  • Patent number: 11651037
    Abstract: The present disclosure relates to a new method for cross-modal retrieval via deep binary hashing and quantization. In a training phase, the system simultaneously learns to generate feature vectors, binary codes, and quantization codes for data across two or more modalities that preserves the semantic similarity correlations in the original data. In a prediction phase, the system retrieve a data item in a database that is semantically similar to a query item of a different modality. To identify the database item closest in semantic meaning to the query item, the system first narrows the database search space based on binary hash code distances between each of the database items and the query item. The system then measures the quantization distances between the query items and the database items in the smaller search space. The system identifies database item have the closest quantization distance to the query item as the closest semantic match to the query item.

  • Patent number: 11651338
    Abstract: A system for avoiding an access conflict between a plurality of devices that access an IC module. The system includes a first device and a second device that can access an IC module used in an electronic money system. The second device has the function of detecting waves having a predetermined pattern to indicate that the first device is accessing the IC module. These waves may be continuously generated from the first device or may be continuously generated from another device installed near the first device, and when the second device detects the waves having the predetermined pattern, the second device refrains from accessing the IC module. This allows the system to implement autonomous conflict control between a plurality of devices that access the IC module that does not have an adequate conflict control function without providing a special control circuit.

  • Patent number: 11645040
    Abstract: A device searches a file being recorded that includes lines sorted in accordance with keys included in the lines to find a line that matches a pattern. When the device receives a pattern, it initializes upper and lower limits of a search range and calculates a middle position between the limits. It acquires, from the file, a middle line that starts at or before the middle position and ends after it. If the key included in the middle line matches the pattern, it outputs the middle line and re-sets the upper or lower limit based on whether the key included in the middle line is greater or less than the pattern and, if there is a distance greater than a length of a newline between the limits, repeats the procedure starting from the middle position. Otherwise, it outputs a result to the effect that no matching line has been found.

  • Patent number: 11643203
    Abstract: An unmanned aerial vehicle, including: a propelling device configured to generate a downward airstream; a package carrier; and wheels arranged so as to allow the package carrier to stand alone. The package carrier includes: vertical members which surround a package in a horizontal direction to prevent falling of the package; support members configured to support a load of the package at positions; and a coupling device configured to hold vertical members so as to enable relative horizontal movement. The support members are each fixed to a corresponding one of the vertical members. The wheels are each mounted to the corresponding one of the vertical members, and enable the relative horizontal movement of the vertical members under a state in which the wheels are on the ground. Through the relative horizontal movement of the vertical members, the package is separable from the support members.
