[0044] The basic idea of ​​SVM learning is to solve the separating hyperplane that can correctly divide the training data set and have the largest geometric interval. Separating hyperplane, for linearly separable data sets, there are infinitely many such hyperplanes (ie, perceptrons), but the separating hyperplane with the largest geometric interval is unique.

[0045] ElasticNet is also called elastic network regression.

Description

technical field [0001] The application belongs to the technical field of oil-gas two-phase flow flow, and in particular relates to a device and method for measuring parameters of oil-gas two-phase flow. Background technique [0002] In modern society, the oil industry has become the foundation of the world economy, how to effectively exploit oil is an urgent problem. Among them, accurate measurement of oil and gas two-phase parameters is one of the bottlenecks in oil recovery technology. In the traditional measurement method of oil and gas two-phase flow parameters, the multiphase mixture needs to be separated in the oil well to measure the flow rate of single-phase flow. Although this method improves the measurement accuracy of single-phase flow, the separation process is complicated, the equipment is expensive, and the measurement efficiency is low. Therefore, it is necessary to find an accurate and efficient online measurement technology for multiphase flow. [0003] R...
