An electronic apparatus is provided. The electronic apparatus includes: an input interface; a memory configured to store a plurality of weights corresponding to an artificial intelligence model; and a processor configured to perform a neural network computation with respect to input data provided through the input interface based on the plurality of weights. The processor is also configured to, based on any one or any combination of the input data, the plurality of weights, and a computation result obtained in a process of performing the neural network computation being within a threshold range, change an original value within the threshold range to a preset value and perform the neural network computation based on the preset value.
