Figure 4 is a flow chart showing a method of operating the scalp care total solution subscription platform of the present invention, Figure 5 is a block diagram showing a system used in the method of operating the scalp care total solution subscription platform of the present invention.

The method 1000 of operating the scalp care total solution subscription platform of the present invention can be performed in a system including a user terminal 1, a network 2, and a main server 3. The user terminal 1 may be a terminal provided with a web page, an app page (app list), a program or an application related to the method 1000 for operating the scalp care total solution subscription platform of the present invention.

In this case, the user terminal 10 may be implemented as a computer capable of accessing and connecting to the main server 3 in a remote place through the network 2 .

In detail, the user terminal 1 is a wireless communication device, navigation, PCS (Personal Communication System), GSM (Global System for Mobile communications), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), International Mobile Telecommunication (IMT)-2000, Code Division Multiple Access (CDMA)-2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (Wibro) terminal, smartphone, smart pad It may include all types of handheld-based wireless communication devices such as smartpads and tablet PCs, and wired communication devices such as general desktop PCs, but is not limited thereto.

The network 2 means a connection structure capable of exchanging information between each node such as the user terminal 1 and the main server 3, and an example of such a network is an RF, 3rd Generation Partnership Project (3GPP) network , LTE (Long Term Evolution) network, 5GPP (5rd Generation Partnership Project) network, WIMAX (World Interoperability for Microwave Access) network, Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), Bluetooth (Bluetooth) network, NFC network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, etc. are included, but are not limited thereto.

The main server 3 may be a server that provides web pages, app pages, programs or applications related to the method 1000 for operating the scalp care total solution subscription platform of the present invention.

The method 1000 of operating the scalp care total solution subscription platform of the present invention includes the steps of uploading user personal information and scalp analysis information to the main server 3 by the user terminal 1 (100); Step 200 in which the main server 3 processes user personal information and scalp analysis information to provide a list of subscription nutritional supplements; Step 300 of the user terminal 1 transmitting selected nutritional information from the list of nutritional supplements to the main server 3; Step 400 of the user terminal 1 transmitting a satisfaction index for a list of subscription nutritional supplements to the main server 3; Step 500 of generating a second artificial intelligence by the main server 3 processing user personal information, scalp analysis information, a list of subscription nutritional supplements, and satisfaction index information, and updating the first artificial intelligence using the second artificial intelligence ; The user terminal 1 transmits the contract information to the main server 3 and proceeds with the contract process (600); may include.

Step 100 in which the user terminal 1 uploads user personal information and scalp analysis information to the main server 3 may be a step in which the user downloads a subscription platform program and registers as a member, and the user receives personal personal information (name) , contact information, gender, age, occupation, ID image, etc.) can be input and transmitted to the main server 3.

In this case, the user's personal information may include information about the user's gender, age, and occupation, and the scalp analysis information may be information obtained by analyzing an image of the user's scalp, and the user uses the user terminal 1.

In step 200, where the main server 3 processes user personal information and scalp analysis information and provides a list of subscription nutritional supplements, the main server 3 processes the user personal information and scalp analysis information using first artificial intelligence. It may be a step of generating a list of subscription nutritional supplements recommended to the user among various nutritional supplements.

On the other hand, since the data that can be obtained from the platform is limited at the beginning of the platform operation, there may be a problem of not securing enough datasets for learning the first artificial intelligence. Accordingly, in the method 1000 of operating the scalp care total solution subscription platform of the present invention, an artificial intelligence prediction algorithm can be generated with virtual data to generate a list of subscription nutritional supplements. A detailed description of generating the above-described first artificial intelligence algorithm will be described later.

The step 400 of the user terminal 1 transmitting the satisfaction index for the subscription nutritional supplement list to the main server 3 may be a step of evaluating the user's satisfaction with the subscription nutritional supplement list recommended by the main server 3. . In this case, the satisfaction index information may be a natural number value that absolutely evaluates the list of subscription nutritional supplements provided from the main server 3, but is not limited thereto.

Step 500 of generating a second artificial intelligence by the main server 3 processing user personal information, scalp analysis information, a list of subscription nutritional supplements, and satisfaction index information, and updating the first artificial intelligence using the second artificial intelligence may be a step of updating the first artificial intelligence with the second artificial intelligence learned from the actual user personal information, actual scalp analysis information, and user's actual satisfaction index information for the actual subscription list of nutritional supplements in the main server 3.

In other words, at the stage when the operation of the platform is stabilized, a new artificial intelligence prediction algorithm is created that updates the above-mentioned first artificial intelligence algorithm in real time by setting the personal information, preferred property information, and satisfaction index information obtained by the platform itself as a dataset. You can continuously create an updated subscription list of nutritional supplements by doing so. A detailed description of generating the above-described second artificial intelligence algorithm will be described later.

In the step 600 in which the user terminal 1 transmits contract information to the main server 3 and proceeds with the contract process, the user selects a specific subscription nutritional supplement from the list of subscription nutritional supplements provided by the main server 3 and regularly selects the subscription nutritional supplement. It may be a stage of proceeding with a contract to purchase.

On the other hand, at the beginning of the contract, the user prepares the scalp care escaper 10 of the present invention by rental or ownership transfer method, receives a subscription list of nutrients periodically recommended from the platform, and applies it using the scalp care escaper 10 can

Hereinafter, artificial intelligence used in the method 1000 of operating the scalp care total solution subscription platform of the present invention will be described in detail. Artificial intelligence (AI) is a field of computer engineering and information technology that realizes human learning ability, reasoning ability, perception ability, and natural language understanding ability through computer programs. In particular, supervised learning, which is used in the most fields of artificial intelligence, is a method of predicting future values using training data including correct answers (labels).

For reference, machine learning can be defined as a methodology that gives computers the ability to learn on their own without being explicitly programmed. Machine learning is divided into supervised learning and unsupervised learning depending on whether or not the correct answer is specified in the data required for learning, classification that divides data into finite categories according to the purpose of use, and continuous It is divided into regression methodology that maps to values, clustering method that groups similar data, and dimension reduction methodology that maps multidimensional data to a representative lower dimension.

Deep learning, one of the machine learning techniques, has dramatically improved the performance of machine learning, which has been stagnant for a while. , The deep learning structure is a deep neural network (DNN) in which multiple hidden layers exist between the input layer and the output layer, and a filter required for factor extraction in front of the hidden layer. It may include a Convolutional Neural Network (CNN) that learns filters together with , and a Recurrent Neural Network (RNN) capable of processing time-series data by stacking artificial neural networks of each time. Here, the high performance of the deep learning model is explained in two ways. First, the neural network is a universal approximator that can approximate all kinds of functions by overlapping the weighted sum of functions in each layer. If sufficiently general data is given, Data can be replicated with high accuracy. Second, in order to classify data well, it is important to properly extract factors representing the data, and optimal factors can be extracted through filter learning using a convolutional neural network. In addition, deep learning is a form in which a model in the field of artificial intelligence called a neural network has been developed, and a structure in which a hidden layer of an artificial neural network composed of a hierarchical structure is composed of several steps. Recent deep learning models have many internal layers, and the number of weights (meaning the strength of connection) connecting nodes can reach up to billions.

In the method 1000 of operating the scalp care total solution subscription platform of the present invention, since data for learning artificial intelligence is insufficient in the initial stage of operation of the platform, the main server 3 provides virtual user personal information and virtual scalp analysis information. By using the first artificial intelligence that learns a dataset set as a feature value of a list of virtual subscription nutritional supplements classified by a manager as a label value, the user's personal information and scalp analysis information input by the actual user terminal 1 are input. You can create a list of subscription nutritional supplements.

That is, the main server 3 learns artificial intelligence with virtual user personal information (label value), virtual scalp analysis information (label value), and a virtual subscription list of nutritional supplements (feature value), so that real users can use user personal information and scalp analysis information, it is possible to generate a first artificial intelligence prediction algorithm that outputs a list of subscription nutritional supplements that match it.

Furthermore, in the method (1000) of operating the scalp care total solution subscription platform of the present invention, when the operation of the platform is stabilized, artificial intelligence is learned with data generated within the platform itself, and the first artificial intelligence algorithm is provided with feedback. 2 AI prediction algorithms can be created to update the 1st AI algorithm in real time.

In detail, the main server 3 uses the user's personal information accumulated by a plurality of users, scalp analysis information, and a list of subscribed nutrients as label values, and the second artificial intelligence that has learned the satisfaction index as a feature value to provide specific nutrients. When a specific list of nutritional supplements is recommended to preferred users, the user's satisfaction index can be predicted. Next, the main server 40 inputs the virtual user personal information set by the existing manager, the virtual scalp analysis information, and the virtual subscription list of nutritional supplements to the second artificial intelligence as label values in order to train the first artificial intelligence. Then, the user's satisfaction index information can be predicted. Next, the main server 40 selects the second artificial intelligence among a plurality of data sets for virtual user personal information, virtual scalp analysis information, and virtual subscription list of nutritional supplements set by the manager to train the first artificial intelligence. First artificial intelligence by excluding the data set in which the value of the satisfaction index information derived by entering into is less than the average value of the preset satisfaction index (the average value of the satisfaction index evaluated by a plurality of actual users) from the data set for learning the first artificial intelligence. can be updated in real time. In this case, the first artificial intelligence continuously receives and learns the virtual user personal information newly set by the manager, the virtual scalp analysis information, and the virtual subscription list of nutritional supplements, so the absence of learning data does not occur and evolves according to the user. can do.
