Electronic apparatus implementing artificial intelligence model having low resource utilization and control method thereof

Abstract

An electronic apparatus is provided. The electronic apparatus includes a memory configured to store an artificial intelligence (AI) model including a plurality of layers and a processor, and the AI model may include a plurality of weight values that are scaled based on shift scaling factors different by a plurality of channels included in each of the plurality of layers and quantized by the plurality of layers, and the processor may, based on receiving input data, in a neural network computation process for the input data, compute a channel-wise computation result with an inverse-scaled composite scale parameter based on a shift scaling factor corresponding to each channel.
