Abstract: Based on a relation model representing a relationship between first data and second data, second data in an evaluation period is calculated from first data in the evaluation period. An evaluation value pertaining to the evaluation period is calculated by using an evaluation model and the calculated second data in the evaluation period, the evaluation model including the second data as a parameter. First data in the evaluation period in a case in which the calculated evaluation value increases are determined.

Abstract: Automated negotiation agent adaptation is performed by detecting change in a utility function involved in automated negotiation between a supporting agent and an opposing agent while the supporting agent operates according to a first negotiation strategy model, generating a plurality of training samples from automated negotiation between the supporting agent and the opposing agent while the supporting agent operates according to a baseline negotiation strategy model, and training an initialized negotiation strategy model using the plurality of training samples to produce a second negotiation strategy model.

Abstract: The planned route creating unit 3 creates a planned route of the self-driving vehicle 10. The non-traveling area plan creating unit 4 creates a plan of the non-traveling area, which is an area where the self-driving vehicle 10 can travel and which is an area set as an area where the self-driving vehicle 10 does not travel. The non-traveling area plan creating unit 4 creates a plan of the non-traveling area at a frequency lower than the frequency at which the planned route creating unit 3 creates a planned route. The transmission unit 6 transmits the plan of the non-traveling area to the other vehicle each time the plan of the non-traveling area is created.

Abstract: An object is to provide a clustering system capable of performing clustering of a plurality of types of items to be able to recommend an item whose corresponding textual data exists but relational data with another type of item does not exist, to the other type of item. A first clustering means 3001 performs clustering of first IDs, based on the relational data. A second clustering means 3002 performs clustering of second IDs, based on the relational data and textual data associated with the second IDs. A topic assignment means 3003 assigns a topic for each word included in textual data corresponding to each second ID. A parameter decision means 3004 decides a parameter used for first clustering processing, a parameter used for second clustering processing, and a parameter used for topic assignment processing. The processing described above is repeated until it is determined that a predetermined condition is satisfied.

Abstract: A learning means 71 learns, on the basis of learning data including a table including a meaning of a column, and a meaning of the table, a model indicating regularity between a distribution of attribute values according to the meaning of the column in the table and the meaning of the table. An estimating means 72 estimates, on the basis of a distribution of attribute values according to a meaning of a column in an input table and the model, a meaning of the table.

Abstract: A co-clustering system capable of further improving prediction accuracy of a prediction model for each cluster is provided. Based on first master data, second master data, and fact data indicating a relation between a first ID which is an ID of a record in the first master data and a second ID which is an ID of a record in the second master data, the co-clustering means 71 executes co-clustering processing of co-clustering the first IDs and the second IDs. The prediction model generation means 72 executes prediction model generation processing of generating a prediction model for each cluster of at least the first ID. The determination means 73 determines whether or not a predetermined condition is satisfied. The prediction model generation processing and the co-clustering processing are repeated until it is determined that the predetermined condition is satisfied.

Abstract: A learning means 71 learns, based on learning data containing the meaning of a column in a table and the meaning of the table, a model indicating regularity between the meaning of the column in the table and the meaning of the table. An estimation means 72 estimates the meaning of the table based on the meaning of a column of a table to be input and the model.

Abstract: A table operation system capable of altering the configuration of a table such that a condition for obtaining easily analyzable information can be designated is provided. A data acquiring means 72 specifies individual tables to serve as reference destinations of designated respective foreign key columns and, for each combination of key values in primary key columns of the specified individual tables, acquires a total value of relation values in a designated relation value column. A grouping means 73 groups the respective key values in the primary key columns of the individual tables on the basis of the total value acquired for each combination of the key values in the primary key columns of the individual tables and a statistical model of a designated type. An attribute value column adding means 74 adds, to each individual table, an attribute value column of which attribute value is identification information on a group to which each key value in each primary key column of each individual table belongs.

Abstract: A path finding apparatus acquires vehicle information and map information, and determines a path set that includes a path for each of the vehicles in the vehicle set. The path set is determined using the vehicle information and the map information. The paths in the path set do not conflict with each other. To determine the path set, the path finding apparatus performs a path planning algorithm to generate the path for each of the vehicles. The path planning algorithm evaluates the path based on a utility score of the path that is a scalar value representing how much the path achieves a plurality of objectives.
