Electronic apparatus and method for controlling thereof

A method for controlling an electronic apparatus, the method comprising:

• identifying, from among weight values included in weight data, at least one weight value having a size less than or equal to a threshold value;
• quantizing remaining weight values other than the identified at least one weight value to obtain first quantized data including quantized values corresponding to the remaining weight values;
• identifying, from among the quantized values, a quantized value closest to a predetermined value;
• obtaining second quantized data including a quantized value corresponding to the at least one weight value based on the quantized value closest to the predetermined value;
• and
• storing the first quantized data and the second quantized data,
• quantizing the neural network model by modifying the at least one weight value based on the second quantized data and modifying the remaining weight values based on the first quantized data to obtain a quantized neural network model, and
• obtaining output data by providing input data to the quantized neural network model.

A method for controlling an electronic apparatus, the method comprising:

• obtaining a weight values included in weight data of a neural network model;
• selecting, from among the weight values, a first weight value to be pruned from the weight values;
• quantizing remaining weight values other than the first weight value to obtain quantized weight values corresponding to the remaining weight values;
• identifying, from among the quantized weight values, a smallest quantized weight value;
• based on the smallest quantized weight value, determining a first quantized weight value corresponding to the first weight value;
• storing the quantized weight values and the first quantized weight value;
• quantize the neural network model by modifying the at least one weight value based on the second quantized data and modifying the remaining weight values based on the first quantized data to obtain a quantized neural network model;
• and
• performing a computation using the quantized neural network model.
