Abstract: There is provided with an information processing apparatus. An acquisition unit acquires a plurality of pattern discrimination results each indicating a location of a pattern that is present in an image. A selection unit selects a predetermined number of pattern discrimination results from the plurality of pattern discrimination results. A determination unit determines whether or not the selected predetermined number of pattern discrimination results are to be merged, based on a similarity of the locations indicated by the predetermined number of pattern discrimination results. A merging unit merges the predetermined number of pattern discrimination results for which it was determined by the determination unit that merging is to be performed. A control unit controls the selection unit, the determination unit, and the merging unit to repeatedly perform respective processes.

Abstract: An apparatus comprises a storage control unit that divides, into two-dimensional blocks, a feature image of a layer and stores the respective blocks in any one of a predetermined number of memories; an unit that determines a pattern for reading blocks from the memories based on information relating to an operation on the feature image; and an unit that reads blocks from the memories in accordance with the pattern. The storage control unit assigns repeatedly, for the two-dimensional blocks, the memories in a predetermined order from a head row/column along a row/column. In a second or subsequent row/column, a memory that the assignment is started is shifted by a constant number from a previous row/column in the predetermined order.

Abstract: There is provided with a data processing apparatus. An acquisition unit acquires feature plane data of a layer included in a neural network. A control unit outputs a first control signal corresponding to the layer for controlling first compression processing and a second control signal corresponding to the layer for controlling second compression processing. A first compression unit performs the first compression processing corresponding to the first control signal on the feature plane data. A second compression unit performs the second compression processing corresponding to the second control signal on the feature plane data after the first compression processing. A type of processing of the second compression processing is different from the first compression processing.
