Abstract: An electronic control device is mounted on a vehicle having a sensor, and includes: a storage unit that stores a control history in which a vehicle control condition and an actual number of measurement times of the vehicle control condition are associated with each other, the vehicle control condition being a condition for performing an arbitrary vehicle control operation for each position; a position specifying unit that specifies a position of the vehicle; a determination unit that determines a current sensor capability that is a current capability of the sensor; and a selection unit that selects, from the storage unit, the vehicle control condition having the largest actual number among the vehicle control conditions that have a position within a predetermined distance from the position specified by the position specifying unit and that can be determined by the current sensor capability.

Abstract: An update system includes an electronic control device that stores an autonomous driving logic and a server. The server includes: a storage unit storing personal characteristic data based on a user's driving and associated driving result data. In creating a first personal characteristic data associated with a first user ID and a first position, if first driving result data is present, the personal characteristic creating unit creates the first personal characteristic data using the first driving result data. If the first driving result data is not present, the personal characteristic creating unit creates the first personal characteristic data using the driving result data or the personal characteristic data associated with a user ID specified for the first user ID by the similarity specifying unit and the first position. The electronic control device includes a personal characteristic updating unit configured to update the autonomous driving logic using the first personal characteristic.

Abstract: An information processing apparatus includes an analysis target acquisition unit, an image processing unit, an inference unit, an inference result extraction unit, and a basis generation unit. The image processing unit generates a plurality of masked images by masking each of the images using a plurality of masks. The inference result extraction unit extracts an inference result at the target coordinates designated in the image from the inference result of each masked image. Based on the inference result at the target coordinates extracted by the inference result extraction unit and the plurality of masks, the basis generation unit generates a basis map visualizing the determination basis for the classification result of the image by the model.

Abstract: Automotive navigation map data has a multilevel structure in which links have a relationship of association with one another among the minutest level and upper levels that are different from the minutest level in scale. A lowermost-level translation unit uses as original data items old and new RDB-form map data items of the minutest level to produce RDB-form difference data of the minutest level. An upper-level difference translation unit produces CSV-format data of a difference of each of the levels of the multilevel structure on the basis of CSV-format data, into which the difference data of the minutest level is translated, and information on the relationship of association among the links of the upper and lower levels in the automotive navigation map data, and integrates the difference data items as final map difference data for an automotive navigation map.

Abstract: It is provided a spatio-temporal data management system for managing time series data associated with a spatio-temporal region, comprising: a processor for executing a program; a memory for storing the program; and a storage device for storing the time series data. The processor segments the spatio-temporal region in time and space to generate a plurality of spatio-temporal segments, assigns, in consideration of temporal and spatial proximity of the plurality of spatio-temporal segments, identifiers for uniquely identifying the plurality of spatio-temporal segments, each of the identifiers being expressed with a one-dimensional integer value; and determines an arrangement of the time series data so that pieces of data of spatio-temporal segments that are close in the assigned identifiers are arranged close on the storage device.

Abstract: A map data distribution server that is connected to a network and distributes map data via the network is provided. The map data distribution server holds first map data and second map data that is of a newer version than the first map data and holds a plurality of update data including an instruction to update the first map data for each of partitions of a given size on a map. The map data distribution server decides whether a predetermined condition is fulfilled upon receiving an update request to update the first map data in a first partition out of the partitions to the second map data from a terminal communicating with the map data distribution server via the network, selects one of the plurality of update data relevant to the first partition, based on the result of the decision, and transmits the selected update data to the terminal.

Abstract: In the situation where an amount of information on a user action history is small, information which is unexpected and interesting to a user cannot be presented with high accuracy. In order to solve this problem, a general degree of unexpectedness of an item, which does not depend on the user action history, and a degree of preference of the user to the item, which is based on the user action history, are calculated in an integrated manner, whereby the information which is unexpected and interesting to the user is recommended.

Abstract: A document retrieval is performed with similarities between documents in numeric data taken into consideration. To this end, generated is a set E of intervals in which each element of a set D of numeric values representing a feature A is included in any one of the intervals. Each numeric value in each document is indexed by assigning, with 1, an interval including an element x of the set D, and with 0, an interval without the element x. Each document data including numeric values is indexed by indexing its text part with term frequencies, and by indexing its numeric-value part with the above-described numeric value indexing scheme. By use of indices thus created for each of the document data, similarities between the document data are calculated using a vector space model or a probability model, and the document data are presented in order of similarity.
