Study On Model Of Volleyball Technology Evaluation Based On BP Neural Network

Volleyball, as our country's traditional sports has become our country sports colleges and universities sports education professional students is one of the compulsory course, is also a complete sports education professional training objectives of an important link.In the common course for the volleyball teaching's main task is to make the students master basic theoretical knowledge and the basic principle and tactics of volleyball, the acquisition of basic technique specification and organizational ability to apply the basic tactics, training students' unity cooperation, their team spirit of courage and the students' ability of volleyball teaching.However, how to scientifically monitoring in teaching volleyball teaching process, and objectively evaluate the teaching quality of volleyball general repair and timely feedback on student's learning effect, this is an important link in the process of volleyball teaching.The underground water quality evaluation method are many, mainly with the traditional subjective evaluation method, the regression analysis method, analytic hierarchy process and fuzzy mathematics comprehensive evaluation method, etc.Although the evaluation method of each has certain advantages, but most need to construct the membership function and to determine the weights.And the design of the membership functions of artificially, the calculation method of weighting are unreasonable, therefore, in some cases, will be lost more valuable information.The working mechanism of artificial neural network structure is to the human brain's organizational structure and activities of the law as the background, it in some extent and level mimics the human nerve system of information processing, storage and retrieval functions, so it has learning, memory and computing intelligence processing function.The purpose of this paper is to through electronic computer method and neural network technology experts and professors to volleyball technical evaluation knowledge experience a more objective and accurate simulation copy down, as well as applications of volleyball teaching practice for us.Main work of this study are:(1) the design of the technical evaluation index system of volleyball general lessons;(2) in the common course for the experts of volleyball technique examination scores of every index data collection;(3) establish a technical evaluation of volleyball general lessons of neural network model(4) the model validation and analysisFinally, after testing and verification, this paper established the principle of neural network based on volleyball teaching and research section experts experience and establish the technical evaluation of volleyball general lessons neural network model is useful.
