Abstract
In order to realize the evaluation of the rationality of an innovative talent training mode, an evaluation model of the rationality of the innovative talent training mode based on a BP neural network is proposed. On the basis of clarifying the principle of the BP neural network model, according to the method of parameter multisource control analysis, the multi-objective characteristic analysis of the rationality of the innovative talent training mode is realized to measure the difference and balance between the two variables of the rationality of the innovative talent training mode. A BP neural network algorithm is designed to find the best feature subset, and a feature sequence sampling and recombination model is constructed. Through reliability evaluation and nonparametric quantitative feature estimation, quantitative analysis and evaluation of the rationality of the innovative talent training mode are realized. The test results show that the confidence level and reliability of the rationality evaluation of the innovative talent training mode using this method are high.
1. Introduction
At present, there is a common problem in talent training in colleges and universities to varying degrees: that is, the problem of “short” and “lack” of elements, such as the talent training mode, follows the old system, and the training objectives and specifications of innovation and entrepreneurship are not clear; or there are various problems in the training process, or the management and evaluation system is imperfect or even lacking; or the way and method are single and lack of incentive mechanism. The limitations of its innovation and entrepreneurship education are as follows: only relying on a small number of lectures on entrepreneurship, relying on entrepreneurship plan competitions, or opening a very limited number of entrepreneurship public elective courses, and there is no systematic framework for the entrepreneurship education curriculum system [1–3].
In the traditional methods, the evaluation algorithms for the rationality of creative genius cultivation pattern mainly include the particle swarm optimization (PSO)-based rationality evaluation algorithm, statistical analysis algorithm, and association rule feature extraction algorithm. Through the statistical analysis of the rationality time series of creative genius cultivation pattern [4–6], the rationality evaluation of creative genius cultivation pattern is realized by the method of correlation feature detection. When the adaptability of the above methods for evaluating the rationality of creative genius cultivation pattern is not good, it is necessary to conduct comprehensive and objective analysis and research on the rationality of creative genius cultivation pattern. As an important research method, computational intelligence and knowledge network pay attention to the network relationship between computational intelligence and network structure [7, 8]. Based on this, this paper attempts to effectively combine the knowledge network with the scale to test the rationality of the innovative talent training mode, and try to find the relationship between the dimensions in the scale in order to better evaluate the innovative talent training mode and solve the problem of the innovative talent training [9].
Therefore, this paper puts forward the rationality evaluation model of innovative talent training mode based on a BP neural network. The BP neural network algorithm [10] is used for finding the best feature subset. Based on the feature selection method of regular term, a feature sequence sampling and recombination model for the rationality of the innovative talent training mode is constructed. Combined with the BP neural network and the machine learning method, the reliability evaluation and nonparametric quantitative feature estimation of the rationality of the innovative talent training mode are carried out. The sample regression analysis model is constructed to conduct quantitative analysis and evaluation of the rationality of the innovative talent training mode. Finally, the empirical analysis is carried out and the conclusion of effectiveness is drawn.
2. Theoretical Basis of Rationality Evaluation of the Innovative Talent Training Mode
In order to realize the rationality evaluation of the innovative talent training mode based on the BP neural network, it is necessary to first build a statistical analysis model for the rationality evaluation of the innovative talent training mode. The BP neural network is a multilayer feedforward network trained according to error backpropagation (error backpropagation for short). Its algorithm is called the BP algorithm. Its basic idea is the gradient descent method, which uses gradient search technology to minimize the error mean square deviation of the actual output value and expected output value of the network [11, 12]. Figure 1 shows the structure of the BP neural network.
Suppose , , and are the input layer node, hidden layer node, and output layer node of the BP neural network, respectively. The connection weight between and is ; the weight between and is . The detailed learning process is as follows:(1)Network initialization. The random value of interval is defined as the network weight and threshold.(2)Output calculation of each layer.(3)Calculate the error of the output layer node.(4)If the error results meet the expected requirements, this is the end. If not, further correction is required.(5)Modify the network weight.(6)Update the network threshold.
If the calculation result is not within the predetermined range, the above process must be repeated until the output error meets the predetermined interval, and the BP neural network training is ended. Thus, the implementation structure of rationality evaluation of the innovative talent training mode based on the BP neural network is shown in Figure 2.
The structure shown in Figure 2 can be summarized into four parts: (1) the data acquisition part of indicator parameters, data management, report management, and visual management; (2) extraction of the training characteristics of innovative talents; (3) rationality evaluation and nonparametric quantity feature estimation; and (4) output of the evaluation results of the innovative talent training mode.
It is necessary to optimize the curriculum structure of creative genius under the background of talent strategy, emphasize the cultivation of methods and abilities, ensure the education quality of creative genius under the background of talent strategy, and promote the teaching reform of creative genius under the background of talent strategy [13–15].

3.1. Feature Selection of Rationality Evaluation of Creative Talent Cultivation Pattern
Using traditional statistical methods, the nine dimensions in SCL are divided into four categories, and a statistical analysis model for evaluating the rationality of the innovative talent training mode is established. A figure is calculated by some mathematical method. The calculation methods can be divided into three types: (1) the method of calculating based on the known number or quantity—the calculation method follows a specific relationship; (2) the method of calculating by theoretical reasoning of numbers; and (3) the method of calculating based on the average. In this paper, the second one is selected when constructing the statistical analysis model for the rationality evaluation of the new talent training mode.
According to the Shapiro–Wilk (n ≤ 50) normality test and variance homogeneity test, we except that the leadership and interpersonal/communication ability dimensions do not meet the normal distribution; the other dimensions meet the normal distribution, and the variance is homogeneous. Therefore, the Mann–Whitney U test in the non parametric test is adopted, and the independent-sample t test is adopted for the rest. The scores of each dimension of the two groups’ self-assessment of talents’ ability are inconsistent from high to low. The scores of the two groups’ interpersonal/communication ability are the highest, and the scores of the teaching/cooperation ability are the lowest. The details are shown in Table 1.

According to the attribute clustering of big data on the rationality of creative genius cultivation pattern, a multi-objective programming is carried out, and the multi-objective programming function is obtained as shown in the following formula:where represents the edge node vector of the rational flow load of creative genius cultivation pattern. According to the above analysis, the characteristic sequence sampling and recombination pattern of creative genius cultivation pattern rationality is constructed, and the reliability evaluation of creative genius cultivation pattern rationality is carried out by combining the BP neural network and the machine learning method [23–25].

4. Simulation Analysis
In order to verify the application performance of this method in evaluating the rationality of creative genius cultivation pattern, a simulation test is conducted, and a simulation analysis is conducted by combining 14.0 Matlab 7 and SPSS14.0. When analyzing the cluster diagram of each factor of SCL-90, hierarchical clustering is adopted, which can also be called systematic clustering. In SPSS, the path is analysis-classification-systematic clustering, and variables are selected in clustering. The cluster ice wall chart and cluster tree chart of each factor are analyzed, as shown in Figures 4 and 5, respectively.
Under the background of talent strategy, the management department of creative genius and 201 creative genius under the background of talent strategy conducted a questionnaire survey (209 valid questionnaires were collected in total). The number of people counted was 2,000, and the number of optimization iterations of multi-objective programming was 400. According to the above simulation parameters, the rationality evaluation simulation analysis of creative genius cultivation pattern was carried out.
Taking the data in Figures 3 and 4 as the research object, the fuzzy correlation big data analysis pattern of the rationality of creative genius cultivation pattern is established, and the fuzzy degree evaluation and parameter evaluation of the rationality of creative genius cultivation pattern are carried out by the method of association regularity detection.

The rationality evaluation parameters obtained by the evaluation all have significant differences (P < 0.05), while other factors have no significant differences. The rational distribution of creative talent cultivation pattern is lower than the norm (P < 0.05), and the talent cultivation is significantly higher than the norm (P < 0.05).
In order to further test the reliability of the algorithm in this paper in evaluating the rationality of the innovative talent training mode, statistics are made on the evaluation accuracy of the five universities in the innovative talent training mode using the algorithm in this paper. The statistical results are shown in Figure 7.
It can be seen from the results in Figure 7 that the accuracy rate of evaluating the rationality of the innovative talent training mode using the algorithm in this paper is over 65%, which indicates that the algorithm in this paper can not only effectively evaluate the rationality of the innovative talent training mode, but also has a high evaluation accuracy rate.
On this basis, the computational complexity of the proposed algorithm is calculated by comparing the methods in [4, 5]. The shorter the time of the algorithm, the lower the computational complexity. Therefore, the experiment is conducted with the evaluation time as the test index. The experimental results are shown in Figure 8.
As shown in Figure 8, under the same conditions, the time of the proposed method is the shortest and the maximum time is 6S, which indicates that the proposed method has the lowest computational complexity, the strongest operability, and high practical applicability.
5. Discussion
5.1. Deficiency
(1)The cultural atmosphere of innovation needs to be strengthened. Innovation requires a free, relaxed, and failure-tolerant cultural atmosphere and innovation environment. Although many colleges and universities in China are constantly exploring the innovative talent training mode and formulating the corresponding innovative talent training plans and programs, the cultivation of innovative talents in some colleges and universities is still on the surface, and innovation is not really implemented in teaching.(2)Lack of innovative teachers. At present, there is a lack of innovative and double-qualified teachers in colleges and universities in China. Although some college teachers have high academic qualifications, they lack corresponding work experience, social practice, and innovation consciousness. Teachers in colleges and universities still focus on theoretical guidance and adopt a single teacher-based teaching method. They fail to combine theoretical knowledge with social practice in the teaching process, and cannot actively guide students to develop innovative thinking, innovative spirit, and innovative ability. In addition, some teachers are busy with their own scientific research, pay little attention to the cultivation of students’ innovative abilities, and neglect the development of students’ innovative potential. The lack of innovative and double-qualified teachers in colleges and universities is far from meeting the needs for cultivating innovative talents in colleges and universities.(3)The curriculum system of innovative talents training is not perfect. The imperfection of the curriculum system in colleges and universities is mainly reflected in two aspects: first, undergraduate education lacks courses aimed at cultivating innovative talents. Higher education in China is divided into vocational education and theoretical education. For a long time, higher vocational colleges mainly undertake the task of vocational education, while undergraduate schools mainly undertake theoretical education. Therefore, many undergraduate schools have more theoretical courses, but less or no practical courses for the cultivation of innovative talents; and second, the curriculum system for the cultivation of innovative talents is unreasonable. At present, the practical courses for the cultivation of innovative talents in many colleges and universities are only case studies in the classroom, which do not allow students to really participate in innovative activities, and fail to enable students to think actively when solving practical problems with theoretical knowledge and cultivate innovative ability. Such a curriculum system is still not separated from theoretical teaching.(4)The evaluation mechanism of the innovative talent training is not perfect. At present, the evaluation mechanism of university teachers’ talent training does not include the innovative ability in the assessment criteria, which leads to the teachers blindly pursuing the publication of papers, books, and scientific research projects. Therefore, it is difficult to form a long-term innovative cultural atmosphere, and the quality of the innovative talent training cannot be improved.
5.2. Strategy
(1)We should improve classroom teaching efficiency and lay a solid foundation for students’ innovation. We are in the era of knowledge economy and information technology. Compared with their predecessors, today’s students need to learn so much and have greater pressure. Therefore, we must teach students the most basic and applicable things, teach them how to learn, how to do things, and how to be a person, and encourage them to be brave in challenges and good at entrepreneurship.(2)We should reasonably set up practice links to improve students’ innovation ability. attach importance to teaching practice and highlight the creative nature of education. It is an effective way to cultivate students’ practical ability and arouse their enthusiasm for innovation to emphasize the link to practical teaching and attach importance to the combination of theory and practice. Social work and social practice play a special role in improving students’ comprehensive quality, and cultivating students’ practical ability and innovative spirit. According to the requirements of social and economic development, the university pays attention to updating the practice teaching links and contents, advocates the integration of practice activities with production practice, and strengthens the construction of practice. We should make full use of social resources, make students participate in enterprise production and operation activities during school, shorten the distance between school and society, and improve students’ practical ability.(3)We should closely rely on scientific research and training to cultivate students’ innovative consciousness. We should study how to vigorously develop the third class of industry university research cooperation, and adopt various ways to attract students with certain innovation ability to participate in the scientific research work of teachers so that students in school can gain knowledge in practice, increase wisdom in scientific research, and further expand the ways of using educational resources to train application-oriented talents.(4)We should actively participate in competition activities and induce students’ innovative thinking. The competition is a banner leading modern college students to ignite their passion for innovation, and an important carrier to promote the cultivation of innovative talents in colleges and universities and the construction of an innovative country. Organizing competitions can not only inspire young students’ fighting spirit, arouse their innovative consciousness, and cultivate their innovative spirit and ability, but also promote the creation of a positive campus cultural atmosphere and the activation of students’ extracurricular scientific and technological activities.(5)We should carry out the second class extensively and expand students’ innovation space. The second class is an important part of talent training, an important way for students to practice professional theoretical knowledge and cultivate innovative and practical abilities, and an effective means to improve students’ employment competitiveness. Through practice and exploration, make full use of the form of students’ professional associations, actively organize students to participate in various social practice activities, and gradually form a set of second class implementation plans that are suitable for the training objectives of the major, meet the teaching requirements, and have a relatively perfect system.
