Data processing method and apparatus, and related product

A device for processing data, comprising:

• an acquisition circuit configured to acquire the plurality of pieces of data for a machine learning model, wherein the data is represented in a first data format;
• a distribution circuit configured to distribute the plurality of pieces of data in the first group of intervals based on values of the plurality of pieces of data, wherein the number of the first group of intervals is predetermined;
• a first average value determining circuit configured to determine the first average value of the plurality of pieces of data;
• a first mapping circuit configured to map the data distributed in the first group of intervals to the second group of intervals according to a plurality of different mapping circuits to determine a second average value of the mapped data according to the corresponding mapping circuit, wherein the mapping circuit includes a predetermined number of consecutive intervals starting from the first interval of the first group of intervals, and the ending interval of the mapping circuit is distributed with the plurality of pieces of data that is larger than or located in the end interval;
• the number of intervals in the second group of intervals is related to the second data format, and the accuracy of the second data format is lower than that of the first data format;
• and
• an execution circuit configured to process on the plurality of pieces of data based on the first average value and the plurality of second average values, so that the processed plurality of pieces of data is represented in the second data format.
