[0044] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0045] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation of the present invention.

[0046] The present application embodiment provides a cooking system based on recipes, please refer to the attached Figure 1 ,like Figure 1As shown, the recipe-based cooking system 10 includes a recipe recommendation subsystem 11 and a cooking assistance subsystem 12 .

[0047] The recipe recommendation subsystem 11 includes a recipe tag model 111 and a recipe database 112 .

[0048] The recipe recommendation subsystem 11 is used to: respond to a recipe recommendation request from a target user, obtain recommendation information in the recipe recommendation request, and determine recipe requirement information and a user identifier of the target user in the recipe recommendation subsystem 11 based on the recommendation information; obtain historical recommendation data corresponding to the target user stored in the recipe recommendation subsystem 11 based on the user identifier, and input the recipe requirement information and the historical recommendation data into a pre-trained recipe label model 111, so that the recipe label model 111 generates a target recipe label set, wherein the target recipe label set includes a plurality of labels for recipe generation; obtain a target recipe matching the target recipe label set from a recipe database 112, and recommend the target recipe to the target user; wherein the recipe database 112 records a plurality of recipes consisting of at least one dish.

[0049] The recipe label model 111 is a pre-trained machine learning model for generating a recipe label set based on the recipe requirement information provided by the user and the user's historical recommendation data. The recipe requirement information is obtained by the recipe recommendation subsystem 11 based on the recommendation information in the recipe recommendation request obtained from the target user. For example, the recommendation information may be "I want to eat chopped pepper fish head today" or "I want to eat Sichuan cuisine for dinner." Based on the recommendation information of "I want to eat chopped pepper fish head today", the recipe requirement information can be determined as adding a dish named "chopped pepper fish head" to the recipe; based on the recommendation information of "I want to eat Sichuan cuisine for dinner", the dish requirement information can be determined as the dish labels in the recipe are all "Sichuan cuisine".

[0050] The recipe database 112 is a comprehensive and practical recipe database constructed by collecting and integrating dietary recipe information from multiple channels. Figure 2As shown in the figure, the system collects public data from public data sources such as professional recipe websites, catering companies, nutritionists and diet experts, industry associations, questionnaires, etc. The system strictly cleans, integrates, classifies, normalizes and visualizes the collected data by considering factors such as the nutritional composition of ingredients, food incompatibility, cooking methods, and calorie balance to ensure the accuracy and availability of the data, so as to ensure that the generated recipes are both nutritious and healthy. Using large language models (LLMs), auxiliary tools and existing recipe databases, new basic recipes can be generated. Based on the basic recipes, professionals reproduce the cooking process, re-record and mark relevant data (audio and video recording information, floating range of ingredients, nutritional value, cooking methods, precautions, etc.) to continuously update and improve the recipe database. This process not only enriches the types of recipes, but also improves the quality and applicability of recipes.

[0051] Specifically, the historical recommendation data may include the number of times a recipe or dish is selected after being recommended, and the number of times it is rejected after being recommended. If the recipe or dish is selected many times, the probability of the recipe or dish being recommended subsequently will increase accordingly; if the recipe or dish is rejected many times, the recipe or dish will not be recommended subsequently.

[0052] The historical recommendation data may also include time attributes, for example, the historical data referenced by breakfast, lunch, and dinner are different. Each of the three meals refers to the recipe corresponding to the corresponding meal in history, such as: the historical data referenced by the breakfast recipe also only includes the recipes recommended for breakfast in history; the historical data referenced by the lunch recipe also only includes the recipes recommended for lunch in history. Or, the proportion of the historical data referenced by the breakfast recipe for the recipe of breakfast is greater than that of the other two meals.

[0053] For example, different historical recommendation data have different weights based on the time of recommendation. The weight of historical recommendation data closer to the current moment is higher than that of historical recommendation data farther away from the current moment. In other words, the weight of historical recommendation data is inversely proportional to the time from the current moment.

[0054] The cooking assistance subsystem 12 is used to: respond to the target user's operation instruction for the target recipe, identify the operation instruction to obtain instruction information, and input the instruction information into a pre-trained binary classification model so that the binary classification model 121 can judge the type of the instruction information; when the instruction information belongs to inquiry information, input the instruction information into a pre-trained recipe question and answer language model 122 so that the recipe question and answer language model 122 generates a response that matches the instruction information; when the instruction information belongs to correction information, input the instruction information into a pre-trained recipe correction model 123 so that the recipe correction model 123 determines the step to be corrected in the target recipe targeted by the instruction information, and adjusts the step to be corrected according to the correction information contained in the instruction information; and provide the generated response or the adjusted target recipe to the target user.

[0055] The binary classification model 121 is a model in machine learning that is used to classify input data into two mutually exclusive categories. This type of model is widely used in various scenarios, such as spam detection (classifying emails into spam and non-spam), sentiment analysis (classifying text into positive comments and negative comments), disease diagnosis (classifying disease states into diseased and non-disease), etc. In a binary classification model, there is usually a target variable, which is binary and can be 0 or 1, representing two different categories. The task of the model is to predict the value of the target variable by analyzing the input feature vector. In the training phase, the model learns the relationship between the input features and the target variable, thereby establishing a classification boundary so that new input data can be correctly classified in the testing phase. The binary classification model in this specification can be any one of logistic regression, support vector machine (SVM), decision tree, random forest, and neural network, and this specification does not limit this.

[0056] The recipe question-and-answer language model 122 is a large language model trained based on training data in the cooking field, and the recipe correction model 123 is a machine learning model built based on natural language processing technology and generative adversarial networks.

[0057] In this embodiment, on the one hand, when selecting a recipe, the recipe recommendation subsystem not only takes into account the recipe requirement information obtained by the user's real-time recipe recommendation request, but also takes into account the user's historical recommendation data, so that the selected target recipe is more in line with the user's usage habits and preferences; on the other hand, the cooking assistance subsystem can distinguish the user's instruction information, answer the distinguished inquiries, and modify the recipe according to the correction instructions proposed by the user, thereby increasing the interactivity between the cooking system and the user, and ensuring the smoothness of the user's cooking process.

[0058] In one embodiment, the cooking system also includes an audio device and a mobile device used by the target user; when the recipe recommendation request and / or the operation instruction is the audio data of the target user, the recipe recommendation request and / or the operation instruction is obtained by the audio device; when the recipe recommendation request and / or the operation instruction is the audio data of the target user, the recipe recommendation request and / or the operation instruction is sent by the target user through the mobile device.

[0059] In this embodiment, with the help of cutting-edge big models and NLP technology, the system successfully realizes the synchronous audio-visual interaction between mobile devices and audio devices, improving the user experience. With the strong support of the cooking system, it can accurately and intelligently recommend recipes that suit personal tastes, allowing users to easily master the cooking skills of various delicacies. The recipe correction system is dynamically adjusted according to the user's real-time feedback to ensure that every step of each dish can accurately meet the user's expectations, making the cooking process more refined and personalized. This system not only optimizes the cooking process, but also greatly improves the user's sense of participation and satisfaction in cooking activities through intelligent interaction.

[0060] In one embodiment, the cooking system also includes an audio device and a mobile device used by the target user: recommending the target recipe to the target user includes: providing the target recipe to the user in the form of a voice broadcast; or sending the target recipe to the target user's mobile device in the form of text and graphics for display; providing the generated response or the adjusted target recipe to the target user includes: providing the generated response or the adjusted target recipe to the user in the form of a voice broadcast; or sending the generated response or the adjusted target recipe to the user's mobile device in the form of text and graphics for display.

[0061] In this embodiment, with the help of cutting-edge big models and NLP technology, the system successfully realizes the synchronous audio-visual interaction between mobile devices and audio devices, improving the user experience. With the strong support of the cooking system, it can accurately and intelligently recommend recipes that suit personal tastes, allowing users to easily master the cooking skills of various delicacies. The recipe correction system is dynamically adjusted according to the user's real-time feedback to ensure that every step of each dish can accurately meet the user's expectations, making the cooking process more refined and personalized. This system not only optimizes the cooking process, but also greatly improves the user's sense of participation and satisfaction in cooking activities through intelligent interaction.

[0064] In this embodiment, the system uses large models and NLP technology to accurately identify user needs and achieve personalized recipe recommendations. It is smarter and more efficient than traditional search methods, has high real-time and dynamic capabilities, and combines multiple information for dynamic updates to ensure that recommended recipes are always synchronized with user needs and the environment.

Based on the above historical recommendation data and recipe requirement information, a target recipe tag set with "Qingming, spicy, Sichuan cuisine, Maoxuewang" can be generated. The recipe-related tag sets of each recipe in the recipe database are traversed, and the degree of association between each recipe-related tag set and the target recipe tag set is calculated to determine the target recipe with the highest degree of association. The target recipe is provided to the user.
