## 1. Introduction

Through the evaluation of the effect of medical image multimedia courseware-assisted teaching, combined with the analysis of the use characteristics of medical image multimedia courseware-assisted teaching, it is necessary to evaluate the effect of medical image multimedia courseware-assisted teaching under the multisource information resource as a service (miraas) mode so as to improve the intelligent service level of medical image multimedia courseware-assisted teaching [1, 2].The research on the evaluation of the effect of medical image multimedia courseware-assisted instruction is realized by analyzing the utilization state characteristics of medical image multimedia courseware-assisted instruction [3, 4] and analyzing the data quantification index parameters. In the traditional methods, the attribute parameter analysis of the auxiliary teaching evaluation of medical image multimedia courseware is realized through coordinate convolution information fusion and remote sensing resolution control [5]. Currently, the multimedia resource management method of medical image multimedia courseware auxiliary teaching based on statistical feature extraction [6] is adopted to establish a data classification detection model to realize the auxiliary teaching effect evaluation of medical image multimedia courseware. However, the fusion degree and sharing level of traditional methods for medical image multimedia courseware-assisted teaching effect evaluation are not high. Through multisource remote sensing parameter analysis, combined with high-standard medical image multimedia courseware-assisted teaching construction feature parameter fusion, the medical image multimedia courseware-assisted teaching effect evaluation is realized. However, the traditional methods have low evaluation accuracy and large calculation cost.In view of the above problems, this paper proposes an evaluation method of medical image multimedia courseware assistant teaching effect based on the deep learning algorithm. It shows the superiority of this method in improving the evaluation ability of medical image multimedia courseware. Finally, the simulation test analysis shows the superiority of this method in improving the teaching effect of medical image multimedia courseware.


## 2. Deep Learning Algorithm Theory

Deep learning is to learn the inherent rules and representation levels of sample data. The information obtained in the learning process is of great help to the interpretation of data such as words, images, and sounds [7, 8]. The ultimate goal of deep learning is to enable machines to have analytical learning ability like people and to recognize data such as words, images, and sounds. Deep learning is a complex machine learning algorithm, and its effect on speech and image recognition is far superior to the previously related technologies. Deep learning has made many achievements in search technology, data mining, machine learning, machine translation, natural language processing, multimedia learning, voice, recommendation, personalization technology, and other related fields [9, 10]. Deep learning has made great achievements in search technology, data mining, machine learning, machine translation, natural language processing, multimedia learning, and other related fields. Deep learning is a general term for a class of pattern analysis methods. As far as the specific research content is concerned, it mainly involves three kinds of methods: convolutional neural network, sparse coding, and deep confidence network [11, 12]. After the initial “low-level” feature representation is gradually transformed into a “high-level” feature representation through multilevel processing, complex learning tasks such as classification can be completed with a “simple model”. Therefore, deep learning can be understood as “feature learning” or “representation learning.” Deep learning is a kind of machine learning, and machine learning is the only way to realize artificial intelligence. The concept of deep learning originates from the research of artificial neural networks, and the multilayer perceptron with multiple hidden layers is a deep learning structure. Deep learning forms more abstract high-level representation attribute categories or features by combining low-level features to discover distributed feature representations of data. The calculation involved in deep learning to generate an output from an input can be represented by a flow chart. The depth of the structure usually has 3, 6, or even 10 layers of hidden nodes, as shown in Figure 1.Figure 1
Deep learning model with multiple hidden layers.Each node in the deep learning model represents a basic calculation and a calculated value, and the calculated result is applied to the values of the child nodes of this node. We consider a computational set, which can be allowed in every node and possible graph structure, and define a family of functions. The input node has no parent node, and the output node has no child nodes. Through layer-by-layer feature transformation, the feature representation of the sample in the original space is transformed into a new feature space, thus making classification or prediction easier. Compared with the method of constructing features by artificial rules, using big data to learn features can better depict the rich internal information of data.
