Abstract

The embodiment of the invention provides a data processing method, device and equipment. The method is used for generating a polynomial capable of fitting an activation function, wherein the polynomial is used for replacing the activation function to construct a machine learning model. The method comprises the following steps: determining the number of times of a polynomial and a fitting intervalaccording to feature information of service data; wherein the fitting interval comprises a plurality of sub-intervals; each subinterval corresponds to a weight coefficient; constructing a metric function according to the subintervals and the weight coefficients; the metric function is used for representing the difference degree of the polynomial and the activation function on the fitting interval;calculating a value of an undetermined coefficient in the polynomial according to the metric function; and generating an expression of the polynomial according to the value of the undetermined coefficient.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular, to a data processing method, device, and equipment. Background technique [0002] In the era of big data, there are many data islands. The business data of each natural person is scattered and stored in different companies. Due to competition and user privacy protection considerations, companies do not completely trust each other. In some cases, it is necessary to use business data shared by both parties to train machine learning models under the premise of fully protecting the privacy of enterprise data; in order to use the trained machine learning model to identify the type of business data. [0003] Machine learning models can include activation functions. The activation function in some machine learning models is a transcendental function (such as a Sigmoid function), and the operations involved in the transcendental function include nonlinear ope...
