Introduction
Marketing refers to the process by which a company discovers or explores the needs of prospective consumers and lets consumers understand the product and then purchase the product. Classic business management courses such as MBA and EMBA all regard marketing as an important module for management and education of managers. Marketing is an activity, process, and system that brings economic value to customers, partners, and the entire society in creating, communicating, disseminating, and exchanging products [1,2]. It mainly refers to the process in which marketing conducts business activities and sales behaviors for the market at the same time, that is, the process of transforming business and sales. Marketing strategy is that the company takes customer needs as the starting point and obtains information on customer demand and purchasing power based on experience, as well as business expectations. Organize various business activities in a planned way. It is a series of measurable and controllable activities aimed at improving sales and manufacturer's reputation for a certain target market. It is a combination of multiple marketing methods such as products, prices, channels, promotions, and public relations strategies. Various marketing strategies still have various problems [3][4][5].
is has brought forward transformation and innovation to the marketing development of enterprises such as requirements for development. e effect of the traditional marketing model is diminishing, and the new media interaction model has gradually become a rising star on the market stage. Various APPs developed in conjunction with smart phones have emerged, and they have innovated marketing models. Traditional enterprises have gradually begun to innovate marketing methods in new dimensions. So, what we see is that new media platforms such as various apps, WeChat, Weibo, and Douyin continue to push all kinds of information to consumers. In order to keep up with market development, major companies have launched their own official channels on new media platforms to innovate information dissemination and marketing methods. e BP sketch is shown in Figure 1.
For traditional catering companies, in the face of this era of "fragrant wine fears no dark alleys," they must also take advantage of the power of new media platforms to be better e times have developed even greater. Researching the development of mainstream catering operations, almost all brand catering companies will build their own APP or official channels based on new media platforms to release or push information. is just shows that the catering industry of the catering industry audience has begun to be affected by the new media. Enterprises reexamine and think about the point of force and development direction: paying attention to the quality of dishes and paying attention to service are only the basis for the development of the industry. e use of new media platforms to carry out marketing planning has become more and more important. In the catering industry, whether it is Internet catering brands, traditional catering brands, or Chinese time-honored brands, they have gradually realized the importance of new media marketing. It is an inevitable choice to compete with peers and stand out in fierce competition [6,7]. However, with the development of network technology, especially the mobile terminal network, people can obtain massive amounts of information on mobile phones or mobile terminal platforms. e era of unreachable big data has arrived. Marketing management has gone through 50 years of research and development. Domestic and foreign scholars have become more and more perfect in marketing management and new media marketing and continue to enrich their basic theories. In terms of researching new media and its marketing concepts, today's industry and academia have not reached a consensus. Different researchers have different research results and focuses.
Yu Guoming pointed out that the characteristics of new media include fragmentation, sharing, and digitization. Jingdong and Su Baohua relied on the definition of "categorical plus species difference" to explore the important position of enterprises in constructing new media marketing and selected the more representative microblogs in new media as the target during the research. Concepts, products, culture, and so on are delivered to more and more consumers through the Internet platform [8].
Liu Ning and Chen Lei analyzed the current growth of new media marketing, and with the help of SWOT analysis methods, they analyzed the external opportunities and tests encountered in the current growth of new media marketing, internal advantages and disadvantages, and mentioned opinions: first, improve the environment in which the online market is located and build a good competition system; second, improve the industry's service system. From sales to after-sales service, a responsible person system needs to be established, and major responsibility issues should be adopted, the method of accountability; the third is to improve the growth and implementation of network marketing to achieve a new situation where the network platform and the previous catering industry can achieve a win-win, share, and common growth [9][10][11][12][13][14].
Gary S. Lynn analyzed the growth path of companies of different scales in the new media environment. After research, it was found that large companies with sufficient funds can support the company's new media marketing strategy, and small companies can also use new media. e feature of low cost promotes part of the marketing work, which means that companies with different scales and marketing companies in a different new media environment can get opportunities in the process of growth. Jay M. Bernhardt and Darren Mays elaborated on the current existing new media platforms and mobile communication technologies. e research gave the view that new media marketing platforms can rely on many channels of communication to stimulate consumers' hidden thinking, and further transform the previous commercial marketing methods. Relevant marketing staff need to explore the influence of new media in their past marketing work and use the new media to explore the true needs of consumers [15,16].
After investigation, Ding Yuping came to the conclusion that consumers' catering requirements no longer rest on their stomachs. ey are increasingly pursuing specialization and diversification in their catering needs. e catering services should be optimized according to the changes in consumer needs; otherwise, they will be cruel.
ere is bound to be no place in market competition. It is necessary to understand that only by seizing consumers can we gain a firm foothold in the market. e catering industry needs to be highly sensitive to the market, and whether it is food conception or service, it needs to be based on consumer experience [17,18].
Du Hongyan studies the continuous integration of services in the catering industry. People's focus is not only on service, but also on the time of serving, the price and taste of the dishes, and so on, which will affect customer experience. e development of catering companies must pay attention to consumers. Feeling, only by exploring, and feeling marketing methods can make customers become repeat customers again. erefore, catering companies should try to explore various experiential marketing methods in the catering industry and promote and adjust the long-term healthy growth of the catering industry through marketing thinking [19][20][21][22][23].
e first historical marketing information obtains the first dimension information of the first merchant; obtains the first degree of influence of the first dimension on the first historical marketing effect; and determines whether the first degree of influence exceeds a first preset threshold. When the first degree of influence exceeds the first preset threshold, it is determined to compose the first dimensional information into a first marketing strategy template; according to the first marketing task of the first merchant and the first marketing, the strategy template obtains the first optimal marketing strategy and sends the first optimal marketing strategy to the first user, thereby solving the problem that the merchants in the prior art cannot control the impact of marketing strategies on marketing effects in real time and cannot effectively and timely optimize the technical problems of marketing strategy and low product conversion rate, achieving timely control of the impact of marketing strategy on marketing effect, continuously optimizing marketing strategy with marketing effect, increasing output value, increasing product conversion rate, and reducing marketing cost. However, it does not solve the problems of the single acquisition method of data resources in the existing marketing strategy, the acquisition of fewer resources, and the inability to achieve deep learning processing of data resources, and the setting and placement of advertisements based on data resources. For this reason, we propose a marketing strategy based on deep machine learning algorithms [24][25][26][27][28].
e concept of deep learning model needs to be traced back to 2006. Geoffrey Hinton used neural network to complete the dimensionality reduction of data and published the results in "Science." Since then, the concept of deep learning has been continuously extended to other fields and has been successfully used. For example, three leading figures in the field of deep learning, Yann LeCun, Yoshua Bengio, and Geoffrey Hinton published a comprehensive research article titled "Deep Learning" in the journal Nature in 2015, in which they launched a detailed study of deep learning. Discussion. In general, the main content of deep learning is that it mainly learns various feature expressions through a model composed of multiple cascaded network layers, and it also has the characteristics of multiple abstract levels. In addition, it also needs to use the backpropagation algorithm to guide the machine to self-learn by changing the internal variables and explore the deeper content contained in the data sample. In fact, this method of using backpropagation or hierarchical models to expand corresponding learning has been used in media such as images, videos, text, and audio. For now, the more successful training network types are Deep Belief Networks based on DBN algorithm, Generative Adversarial Networks based on model optimization training, Long Short-Term Memory to solve RNN, feedforward neural network (English name is Convolutional Neural Networks), and so on. In addition, many scholars have paid attention to the backpropagation algorithm of training the network. erefore, people began to develop more efficient algorithms, including AdaDelta, Adam, and RMSprop [29][30][31][32].
erefore, this paper uses deep machine learning algorithms to process the data information to make the data information easy to view and clear. e advertisement delivery method algorithm calculates the best way of advertising and then calculates the advertisement to deliver.

Deep Learning
Artificial intelligence is considered to be a "knowledge-related subject" due to its comprehensiveness of disciplines, and due to its integration of high-precision technology, it is considered to be able to be used to realize intelligent activities that replace humans with machines, which also represents relevantly the center and core idea of the field. at is, through the frame-by-frame study of human motion trajectories, many commands are given to the machine, and the machine's own knowledge system is even cultivated to replace humans in handling some behaviors/businesses. e research content is mainly to control the machine through code to imitate and learn the characteristics of humans. e act of consciousness conducts learning and knowledge theory and operation (see Figure 2). e success of deep learning methods is inseparable from the following three key factors: (1) large-scale labeled training data sets; (2) convolutional neural networks have unique advantages in feature expression; and (3) powerful computing capabilities.
In addition, there are also documents that propose a method and device for optimizing marketing strategies based on marketing effects. Although it has achieved the first business information of the first business, the first business information includes the first historical marketing information. As the core of artificial intelligence disciplines, machine learning is the basis for making computers intelligent. It has interoperability and tolerance of disciplines and e main content is to use algorithms to enable the machine to have a certain simulation ability, to independently complete some behaviors that only humans can do before, to establish its own knowledge structure and skill system, and to update and improve its knowledge structure in real time. As one of the most important technologies of artificial intelligence, it is the basis for the realization of mechanical intelligence. Generally speaking, machine learning is mainly used to summarize and integrate information, which is then deduced by artificial intelligence.
Deep learning is the core algorithm in machine learning. is definition first appeared in 2006. Researchers such as Geoffrey proposed a technique to reduce the dimensionality of data with the help of neural networks and published this result in the Science journal. is concept is one of the most important advances in artificial intelligence technology in the past decade. It has made great breakthroughs in many technologies, including image and video analysis, audio discrimination, natural language processing, computer hearing, and multimedia. In the current use of neural network models, it teaches computers to think and understand the world in a human way. In 1940, the concept of neural networks began to appear, which is a study of the formation mechanism of brain consciousness and simulations to answer various types of machine learning questions. In 1986, Rumelhart et al. discovered that the backpropagation algorithm can be used in the process of training neural networks. is famous discovery was published in the Nature journal and has been widely used today.
At present, convolutional neural networks can be applied in the field of image recognition with the help of deep learning algorithms, but the collection of large-scale labeled data sets is still a difficult point. Deep learning models are mainly composed of deep neural network models. ese models usually have relatively complex network structures and a large number of parameters. ey often need to rely on a large amount of artificially labeled data for training to obtain good performance in a data-driven manner; for example, ImageNet, an important database in the field of computer vision, has more than 10 million pictures. Normal deep learning model training process. Normal data analysts will write data processing code and model training code based on desensitized sample data in the debugging environment of catering data. After the code is debugged, the data analyst will send it to the operating environment of the catering data. In the operating environment, the data processing code will run on the full amount of training data D, and the processed training data D′ will be obtained, which is defined as follows: Among them, x i and y i are the feature value and label value of each piece of data, respectively. e optimization process of the model is shown in the following formula: Among them, the function L is the loss function of deep learning, which is used to evaluate the difference between the judgment result of the function f θ on x i and the real label value y i . Φ is a regular term, usually used to prevent the AI model from overfitting. e data theft attack method mainly acts on the data processing stage. e attacker maliciously modifies the data enhancement function in the data processing process. is article defines the malicious data DM as shown in the following equation: For the attack in the model training phase, first extract the real number string s from the feature values of the training data. e number of elements in the string is the same as the number of parameters in the model parameter θ, which is k. In the training process, the attacker modifies the regular term as shown in the following equation: where θ and s refer to the average value of all elements in θ and s, and the parameter a controls the influence of the malicious regular term on the training process.
Another attack against the model training phase is In the normal training process, the regular term of the deep learning loss function generally selects the L1 paradigm or the L2 paradigm, as shown in the following equations:
