Abstract: A neural network optimizing device includes a performance estimating module that outputs estimated performance according to performing operations of a neural network based on limitation requirements on resources used to perform the operations of the neural network. A portion selecting module receives the estimated performance from the performance estimating module and selects a portion of the neural network which deviates from the limitation requirements. A new neural network generating module generates, through reinforcement learning, a subset by changing a layer structure included in the selected portion of the neural network, determines an optimal layer structure based on the estimated performance provided from the performance estimating module, and changes the selected portion to the optimal layer structure to generate a new neural network. A final neural network output module outputs the new neural network generated by the new neural network generating module as a final neural network.
