Title: DATA PROCESSING SYSTEM AND METHOD
Abstract:
The embodiment of the invention discloses a data processing device. After using a sub-sample data set to compute a set of gradient information of each parameter, the device deletes the sub-sample data set, then reads a next sub-sample data set, and uses the next sub-sample data set to compute another set of gradient information of each parameter. Then, the device accumulates plural sets of gradient information of each parameter to obtain an updated gradient of each parameter.
