Data Processing Method and Apparatus for Neural Network

A data processing apparatus for a neural network, the neural network provided with at least one activation function, the apparatus comprising:

• at least one processor;
• and
• a memory storing instructions, wherein the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• converting, in response to that an activation function acquiring current data is a target function, based on a conversion relationship between the target function and a preset function, the current data into input data of the preset function;
• obtaining first output data of the preset function with the input data as an input in a lookup table corresponding to the preset function;
• obtaining second output data of the target function with the current data as an input by conversion based on the conversion relationship and the first output data;
• and
• outputting the second output data.
