Abstract: A DNN contraction device (100) outputs a reduced DNN to a DNN computation unit (300) that performs a DNN computation using an internal memory. The DNN contraction device (100) includes an output data size measurement unit (110) and a data contraction unit (120). The output data size measurement unit (110) measures the output data size in the DNN layer from the DNN network information. The data contraction unit (120) sets a contraction number of the DNN layer based on the output data size and the memory size of the internal memory.

Abstract: An autonomous driving system for a vehicle reduces the amount of computations for object extraction carried out by a DNN, using information a traveling environment or the like. An information processing apparatus including a processor, a memory, and an arithmetic unit that executes a computation using an inference model is provided. The information processing apparatus includes a DNN processing unit that receives external information, the DNN processing unit extracting an external object from the external information, using the inference model, and a processing content control unit that controls processing content of the DNN processing unit. The DNN processing unit includes an object extracting unit that executes the inference model in a deep neural network having a plurality of layers of neurons, and the processing content control unit includes an execution layer determining unit that determines the layers used by the object extracting unit.
