Claim 2:
3. An arithmetic operation method performed by an arithmetic operation device, the arithmetic operation device including a memory configured to store a first machine learning model that includes a predetermined number of parameters and is trained so as to output second data corresponding to input first data, processing circuitry configured to execute the arithmetic operation method, and an interface connected to the processing circuitry, the method comprising:
receiving the first data and a required performance related to an inference through the interface, the required performance being provided from outside the arithmetic operation device and including an accuracy of inference using a machine learning model and a computational complexity based on a product of a number of multiply-accumulate computations and a number of bits of weight parameters;
removing a part of parameters of the predetermined number of parameters from the first machine learning model and decreasing the number of bits of weight parameters according to the required performance to generate a second machine learning model, wherein a second accuracy of inference using the second machine learning model is lower than a first accuracy of inference using the first machine learning model but satisfies the received required performance;
inputting the first data into the second machine learning model to acquire third data output from the second machine learning model with a smaller computational complexity than the first machine learning model; and
outputting the third data through the interface.
