Platform patent value evaluation method based on information ecological theory and RF-GA-BP neural network

Abstract

The invention discloses a platform patent value evaluation method based on an information ecological theory and an RF-GA-BP neural network. The platform patent value evaluation method comprises the following steps: analyzing network platform patent value influence factors based on the information ecological theory; obtaining a training sample and a test sample of the GA-BP neural network; performing dimension reduction processing on the platform patent value influence factors by adopting an RF-based feature selection method to obtain an optimal feature subset; designing a BP neural network topological structure, and setting related parameters; optimizing the weight and threshold of the BP neural network by adopting a GA algorithm; and taking the optimal feature subset selected by the RF asan input signal of a GA-BP neural network model, training and checking the GA-BP neural network, and finally constructing a platform patent value evaluation model based on an RF-GA-BP neural networkalgorithm.

Description

technical field [0001] The invention belongs to the field of patent value evaluation, in particular to a platform patent value evaluation method based on information ecology theory and RF-GA-BP neural network. Background technique [0002] With the development of network platforms serving the economic environment, technology trading platforms centered on patents have been launched one after another, such as Technology E Network, Bajie Intellectual Property, etc., and network platform patent transactions have become an emerging patent transaction model. Compared with traditional patent transactions, the online patent transaction platform is like a bridge, which can effectively connect supply and demand sides, provide more complete services, reduce patent transaction costs, alleviate information asymmetry, and play a role in promoting the transformation of my country's scientific and technological achievements. important value. However, with the rapid development of the platfo...

Problems solved by technology

The emerging intelligent patent value evaluation method is still in the preliminary research stage. Most of the existing evaluation models are still based on traditional patent value evaluation indicators. There is a lack of research on the effect of network platform factors in patent value evaluation. There are also some methods The model needs to be improved and optimized to improve its evaluation effect
