ELECTRONIC APPARATUS AND CONTROL METHOD THEREOF

An electronic apparatus may include a memory, and a processor configured to perform an operation between a first index data and a second index data corresponding to a first data set and a second data set, respectively, to acquire first output data; identify a sparsity ratio of the first output data; based on the sparsity ratio exceeding the threshold value, determine a first method of processing the first data set and the second data set using the first data set and the second data set, as an operation method of the electronic apparatus; and based on the sparsity ratio being equal to or less than the threshold value, identify valid data included in the first index data and the second index data, and determine a second method of processing the first data set and the second data set using the valid data, as the operation method of the electronic apparatus.
