  • Patent number: 11762918
    Abstract: A search apparatus causes a first learning process using a first sample size and a first hyperparameter value to be executed, and causes a second learning process using the first sample size and a second hyperparameter value to be executed. When a third learning process using a second sample size larger than the first sample size and the first hyperparameter value has not been executed, the search apparatus calculates total resources associated with the first sample size based on resources used by the first and second learning processes. If the total resources exceed a threshold, the search apparatus allows the third learning process to be executed. If the total resources are equal to or less than the threshold, the search apparatus withholds the execution of the third learning process, and allows a fourth learning process using the first sample size or smaller and a third hyperparameter value to be executed.

  • Patent number: 10061517
    Abstract: A data arrangement apparatus calculates evaluation values for individual relocation processes generated based on an access pattern. Each of the relocation processes indicates a relocation of some of a plurality of unit data pieces in a storage device. The data arrangement apparatus selects, amongst influence range levels whose ranges in relation to unit data pieces to be affected by the relocation differ in extent of influence, one influence range level based on the evaluation values and coefficients associated one-to-one with the influence range levels. Based on the extent of influence indicated by the selected influence range level, the data arrangement apparatus determines one or more relocation processes to be executed amongst the generated relocation processes. Based on access status after the determined relocation processes are executed, the data arrangement apparatus updates a coefficient associated with the selected influence range level.
