## 1. Introduction

With the country’s emphasis on the cultivation of personnel in higher education, the quantitative assessment of the level of personnel cultivation in higher education has attracted people’s attention. As an important part of teaching assessment, the level assessment of higher education personnel develop plays an important role in daily teaching management [1]. Effective level assessment of higher education personnel develop is conducive to understanding the actual operation of school teaching and supervising the normal and standardized operation of various teaching activities. With the continuous large-scale enrollment expansion of colleges and universities in China for many years, the level of personnel cultivation in higher education has increasingly become the focus of social attention [2]. How to improve the level of education and teaching, cultivate high-level personnel, and establish a scientific, reasonable, fair, and equitable assessment system of personnel cultivation level in higher education, so as to discover, analyze, and solve problems in time and objectively, has great historical and practical significance for promoting the development of personnel cultivation in higher education [3].By using big data analysis technology, the assessment model of higher education personnel cultivation level is established, the regression analysis of higher education personnel cultivation level assessment is realized by data mining technology, and the assessment model of higher education personnel cultivation level is constructed by multidisciplinary technology [4]. On this basis, the new technology of higher education personnel cultivation level assessment is developed, which integrates the knowledge of databases, information retrieval, statistics, algorithms, and machine learning [5]. To realize the level assessment of higher education personnel develop, machine learning algorithm is that it can find hidden and valuable information from databases or massive information, sometimes called exploratory data analysis, data-driven discovery, and inductive learning. Generally speaking, data mining is a process of extracting potentially useful information and knowledge from a large number of incomplete, noisy, fuzzy, and random data, which people do not know in advance in the assessment of personnel cultivation level in higher education [6]. With the wide application of large database and network parallel parameter distribution and fusion technology, the scale of higher education personnel develop level constraint index parameters is increasing, so it is necessary to build an optimized personnel develop level assessment model [7]. Combined with the characteristic analysis and fusion processing of higher education personnel develop level constraint index parameters, a personnel develop level assessment model is built, and according to the characteristic distribution of higher education personnel develop level constraint index parameters, the dynamic assessment of higher education personnel develop level is realized, and the information management ability of higher education personnel develop level constraint index parameters is improved [8].The assessment of personnel develop level is based on the analysis of the central characteristics of personnel develop level in higher education. Among the traditional methods, the integration methods of the constraint index parameters of personnel develop level in higher education mainly include the assessment method of personnel develop level based on fuzzy information clustering [9], the assessment method of personnel develop level based on fuzzy detection, and the assessment method of personnel develop level based on joint parameter identification. The fuzzy detection model of personnel develop level assessment is constructed, and the cluster of constraint index parameters of personnel develop level in higher education is realized through joint parameter distribution. Reference [10] puts forward a transient stability assessment method considering the cultivation of higher education personnel and combines the neural network model of message transfer graph to realize the data integration management of the cultivation level assessment of higher education personnel, but the storage cost of this method is large. Reference [11] puts forward an intelligent data mining-oriented personnel develop level model of higher education, which combines decentralized and coordinated robust optimal scheduling and data detection to realize the assessment and data analysis of personnel develop level of higher education. However, this method has high computational cost and poor real-time performance.In view of the above problems, this paper proposes a talent training quality evaluation model based on improved machine learning to realize the mutual information coupling parameter analysis of higher education talent training quality constraint index parameters. The results show that the model has good performance, and the evaluation effect of talent training quality is good.


## 2. Improve the Theoretical Methods of Machine Learning

Machine learning is an interdisciplinary subject, involving probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory, and many other disciplines. Machine learning is the core of artificial intelligence and the fundamental way to make computers intelligent [12]. It is widely used in all fields of artificial intelligence, and it mainly uses induction and synthesis instead of deduction. Some information is provided to the learning part of the environment, and the learning part uses this information to modify the knowledge base, so as to improve the efficiency of the system execution part. The execution part completes the task according to the knowledge base and feeds back the obtained information to the learning part. There are many forms of knowledge representation, such as feature vectors, first-order logical statements, production rules, semantic networks, and frameworks. These representations have their own characteristics. When choosing representations, we should give consideration to strong expressive ability, easy reasoning, easy modification of knowledge base, and easy expansion of knowledge representation. Every learning system requires some knowledge to understand the information provided by the environment, analyze and compare, make assumptions, and test and modify these assumptions. The execution part is the core of the whole learning system, because the actions of the execution part are the actions that the learning part tries to improve. A learning system always consists of two parts: learning and environment [13]. The environment provides information, while the learning part realizes information conversion, memorizes it in an understandable form, and obtains useful information from it. In the process of learning, the less reasoning the learning part uses, the greater his dependence on the environment. Learners directly absorb the information provided by the environment without any reasoning or other knowledge conversion. The systematic learning method is to learn directly through preprogrammed and structured programs, and learners do not do any work or learn directly by receiving established facts and data, without any reasoning about the input information. The improved machine learning algorithm can be adjusted according to training examples, number of features, polynomial degree, and regularization parameters. By obtaining more training examples, the high variance can be solved. Relying on changing the number of features, reducing the number of features can solve the high variance, while increasing the number of features can solve the high deviation. High variance can be solved by changing polynomial degree to reduce polynomial degree, and high deviation can be solved by increasing polynomial degree [14]. Change the regularization parameter: reducing the regularization parameter can solve the high deviation, while increasing the regularization parameter can solve the high variance.


## 3. Data Structure Model and Feature Analysis

### 3.1. Higher Education Personnel Develop Level Constraint Index Parameter Structure Model

The assessment of higher education personnel cultivation adopts the principle of combining analysis with synthesis: the assessment of higher education personnel cultivation is a process. The assessment process must be analyzed first, and the effects and characteristics of each part of the teaching process should be analyzed. Then, on this basis, the overall analysis should be made to judge the level effect of higher education personnel cultivation, which must be synthesized. In this sense, the combination of analysis and synthesis, that is, the principle of combining partial assessment with overall assessment or combining individual assessment with comprehensive assessment with qualitative assessment and quantitative assessment: qualitative assessment is often based on certain observation or experience of teaching [15], which inevitably has subjective components or some one-sidedness, but it cannot be completely ignored. Quantitative assessment is to make a scientific analysis of observation or experience summary through a certain index or index system, in terms of quantity and under a certain confidence level. The quantitative assessment of personnel cultivation level in higher education is quite reliable, because teaching assessment is a complicated process, and it is absolutely reliable because of the selection of index or index system and the influence of systematic error and random error. Therefore, the combination of qualitative assessment and quantitative assessment, mutual reference, and complementarity will reduce the one-sidedness of teaching assessment. In order to realize the dynamic assessment of personnel cultivation level in higher education, this paper combines the heterogeneous reorganization of the big data characteristic distribution of the constraint index parameters of personnel cultivation level in higher education, establishes the big data information analysis model of the constraint index parameters of personnel cultivation level in higher education, and adopts information fusion and characteristic clustering to realize data integration. The overall structure is shown in Figure 1.Figure 1

The distribution sequence A=a1,a2,⋯,an,B=b1,b2,⋯,bm, and the higher education personnel cultivation level constraint index parameters is optimized by online clustering design under the background of big data.

Based on the transmission protocol design mode of higher education personnel cultivation level constraint index parameters, the formal characteristic grouping detection model of higher education personnel cultivation level constraint index parameters is obtained as shown in the following formula:
(2)di=xi2+yi2+zi2.Wherein,xi is the integration parameter of the ith distribution block of higher education personnel develop level, yi is the autocorrelation characteristic matching coefficient of higher education personnel develop level, and zi2D is the fuzzy optimization parameter of higher education personnel develop level assessment. The statistical analysis model of parameter clustering of higher education personnel develop level constraint index is established. In the fuzzy grid area, the statistical analysis of parameter clustering of higher education personnel develop level constraint index is carried out, and the parameter structure distribution model of higher education personnel develop level constraint index is obtained.
