For example, if the data object is a commodity, the corresponding attribute feature may include, but is not limited to, the category, price, sales volume, and location of the product. , efficacy, gender distribution, age distribution, etc. of the user who purchased the product.

After determining the attribute feature of the data object, the feature value v _j of the attribute feature of the data object (the feature value of the attribute feature of the jth data object) may be first obtained, and the attribute feature vector of the data object is calculated according to the feature value v _j

The feature value of the attribute feature can be obtained according to the interface specified by the call.

Mathematically, the linearly transformed eigenvector (eigenvector) is a non-degenerate vector whose direction is unchanged under the transformation. The scale at which this vector is scaled under this transformation is called its eigenvalue (eigenvalue). If the vector v and the transform satisfy Av = λv, then the vector v is a feature vector of the transform A, and λ is the corresponding feature value.

The embodiment of the present application can calculate the attribute feature vector by using a general method for calculating the feature vector according to the feature value. For example, once the feature value λ is determined, the corresponding feature vector can be obtained by solving the equation (A-λ1) v=0, which is implemented by the present application.

In formula (1), the logarithmic function is used to smooth the eigenvalues of the attribute features of the data object. It can be seen that the larger the eigenvalue of the attribute feature of the data object, the data object is The greater the proportion of the data object collection. For example, the larger the sales volume of a product, the greater the proportion of the product in the product combination.

Sub-step S1113, respectively inputting the set feature vector and the user feature vector into a preset prediction model to obtain a predicted preference value of the data object set.

The preset prediction model may be a model obtained by offline training. In a preferred embodiment of the embodiment of the present application, the prediction model may be established in the following manner, but it should be understood that the embodiment of the present application is not limited thereto. It is possible for domain technicians to establish predictive models with the same effect in other ways:

Obtaining a visitor feature vector of a visitor of the second user's associated page in the entire network; acquiring an attribute feature vector of the data object associated with the second user; obtaining all accesses The access behavior data of the visitor of the second user's associated page in the associated page as sample information; modeling the sample information, the attribute feature vector, and the visitor feature vector to generate a predictive model.

Specifically, the calculation method of the visitor feature vector is similar to the calculation method of the user feature vector described above, except that the data of the user feature vector is derived from the access behavior of all visitors of the entire network, and the data of the visitor feature vector is derived from all accesses of the second. The visitor's access behavior for the user's associated page.

That is, the visitor feature vector is obtained according to the visitor feature value, and the visitor feature value is a feature value of the visitor feature, and the visitor feature may include a behavior feature and/or a demographic attribute feature, wherein the behavior feature may include, but is not limited to: a visitor pair The behavior of browsing, collecting, and the like of the data objects associated with the two users; the demographic attribute characteristics may include, but are not limited to, the gender, age, occupation, and the like of the visitor.

The attribute feature vector of the data object is as described in the above sub-step S1111, and will not be described again here.

The access behavior data of all the visitors accessing the associated page of the second user in the associated page may be a visitor accessing the data object in the associated page by the visitor of the associated page of the second user, the access behavior may be expressed as (u, i), where u is the visitor identity of the visited associated page, and i is the data object identifier accessed by the visitor in the associated page.

In a specific implementation, one (u, i) can be used as a sample information. In the (u, i), if u performs a specified operation on i, the sample information is a positive sample, otherwise, if u does not perform a specified operation on i, the sample information is a negative sample. For example, in an e-commerce application scenario, if a user browses an item and purchases the item, the sample is a positive sample. Otherwise, if the user browses an item but does not purchase the item, then the sample Is a negative sample.

After determining the sample information, the attribute feature vector and the visitor feature vector, it can be modeled as a parameter and modeled by a preset modeling algorithm to obtain a predictive model. As an example, the modeling algorithm may be an MPI (Message Passing Interface, which can be used for parallel computing) - GBDT (Gradient Boosting Decision Tree, A machine learning algorithm widely used for classification or regression problems, an iterative decision tree algorithm consisting of multiple decision trees, the conclusions of all trees are added together to make the final answer.

The function of the prediction model is to estimate the probability that a first user will perform a specified operation on a certain data object according to the historical access data of the visitor of the second user's associated page and the attribute characteristics of the data object in the associated page. For example, based on historical behavior data such as in-store visitors and commodities, the probability that a future user will have a purchase relationship for a certain product is estimated.

In a preferred embodiment of the embodiment of the present application, after each set feature vector and user feature vector are respectively input into a preset prediction model, the output user's predicted preference value for each data object set may be expressed as follows:

Sub-step S112, determining a correlation degree between the first user and the data object set respectively;

In a preferred embodiment of the embodiment of the present application, the sub-step S112 may further include the following sub-steps:

Sub-step S1121, respectively calculating a set word vector of the data object set according to a preset word vector model;

To hand over natural language to algorithms in machine learning, you usually need to first mathematicalize the language. Word Embedding (or Word Representation) is a way to mathematicalize words in the language. In the embodiment of the present application, the word vector is used to represent the word vector of each data object.

In one embodiment, the preset word vector model can be generated in the following manner:

Each data object has title information in the specified website, and the title information of each data object in the specified website is used as a corpus, and the corpus is trained by a neural network-based word vector algorithm to obtain a multi-dimensional word vector model, the word vector. The model includes word vectors for multiple data objects.

In a specific implementation, the word vector algorithm based on neural network may include a cyclic neural network algorithm, a recurrent neural network algorithm, etc., and the principle of one of the neural network algorithms is shown below. Example description:

Assuming that the first n-1 data objects in the corpus are wt-n+1,..., wt-2, wt-1, it is now necessary to predict the next data object wt based on the known n-1 data objects. C(w) represents the word vector corresponding to the data object w. The whole model uses a unique set of word vectors, which exists in the matrix C (matrix of |V|×m), where |V| represents the size of the vocabulary (the total number of words in the corpus), m represents the dimension of the word vector. The conversion from w to C(w) is to take a row from the matrix. The first layer of the network (input layer) is C(wt-n+1),...,C(wt-2),C(wt-1) These n-1 vectors are joined end to end to form a (n-1)m-dimensional vector, denoted by x below. The second layer of the network (hidden layer) is calculated directly using d+Hx, and d is an offset term. After that, tanh is used as the activation function. The third layer (output layer) of the network has a total of |V| nodes, and each node yi represents the unnormalized log probability of the next word i. Finally, the output value y is normalized to a probability using the softmax activation function. Finally, the formula for y is:

y=b+Wx+Utanh(d+Hx)

Among them, U(|V|×h matrix) is the parameter of the hidden layer to the output layer. Most of the calculation of the whole model is concentrated in the matrix multiplication of U and hidden layer; W(|V|×(n-1)m) The matrix contains the straight edges from the input layer to the output layer (the straight edge is a linear transformation from the input layer directly to the output layer). If you do not need a straight edge, set W to 0. Finally, the word vector model can be obtained by the stochastic gradient descent rule.

After obtaining the word vector model, the word vector model can also be synchronized to the storage for real-time calculation.

In the embodiment of the present application, the set word vector of each data object set can be calculated according to the word vector model and the attribute features of the data object.

In one embodiment, the set word vector can be calculated using the following formula (2)

为第j个数据对象的词向量。 Where v _j is the eigenvalue of the attribute feature of the jth data object, and is smoothed by a logarithmic function.

The word vector for the jth data object.

Sub-step S1122, acquiring a specified number of data objects that the first user recently browsed, and acquiring an intent word vector of the first user based on the specified number of data objects;

In the embodiment of the present application, the real-time intention of the user may be predicted in combination with the historical browsing behavior of the first user. Specifically, a specified number of data objects that the first user recently browsed (for example, 10 items that were recently browsed in the day) may be acquired, and a word vector of the specified number of data objects is obtained, according to the word vector of the specified number of data objects. To get the first user's intent word vector.

In an embodiment, the first user's intent word vector may be calculated using the following formula (3):

Where T _j is the number of seconds of the data object browsed by the user u from the current time, and α is the attenuation coefficient.

It can be seen from the above formula (3) that the more recently viewed the data object, the greater the contribution to the prediction of the user's current intention.

Sub-step S1123, respectively calculating the intent word vector and the similarity of each set word vector as the degree of relevance of the first user and the corresponding data object set.

After obtaining the first user's intent word vector and the collective word vector of each data object set, the similarity of the two may be separately calculated, the similarity reflecting the degree of correlation between the first user and the corresponding data object set.

In one embodiment, the intent word vector and the similarity of each set word vector may be calculated using the following formula (4):

Sub-step S113, for each data object set, correct the predicted preference value by using the correlation degree, respectively, to obtain an actual preference value of the first user and the data object set.

In the embodiment of the present application, the first user's intent word vector and each set word vector are obtained. After the degree of correlation, the predicted preference value can be corrected according to the degree of correlation, and the actual preference value of the first user and each data object set is obtained.

In one embodiment, the actual preference value can be calculated using equation (5) below:
