The feature intersection can improve the nonlinear modeling capability of the model; the normalization can eliminate the influence of unit and scale differences among features, and the equal view of each dimension of features is ensured; the standardization can accelerate the solving speed of gradient descent and promote the convergence speed of the model; the feature importance analysis is to select features which are more relevant to the model target, so that the complexity of the model caused by excessive features is prevented.
In this step, the combination of the user characteristics of the positive sample and the user characteristics of the negative sample of the front link is divided into a front link training set and a front link verification set, a LightGBM model is selected to fit the front link training set, cross verification is added in the fitting process, the stability of the model is improved, a verification model is formed, the trained model is used to predict the front link verification set, and the model is continuously optimized by the effect of the model on the verification set.
In this embodiment, in this step, the user features are digitized, the user features are used as independent variables, the stay behavior and the non-stay behavior are used as dependent variables, the relationship between the user features and whether the stay behavior exists is fitted through the LightGBM model, and then whether the user features have the stay intention is judged according to the user features of the clients meeting the modeling conditions.
In this step, the user characteristics of the client conforming to the entry condition are input into the verification model, and the client having the intention to stay is output.
S3: the probability of having intent to go to the store, test drive, place order and deal is determined based on the user characteristics of the customer with intent to stay.
In this embodiment, in S3, a classifier needs to be built and trained to output probabilities of arrival at the store, test driving, placing orders, and deals.
In this embodiment, a plurality of types of basic classifiers, such as a random forest classifier, a LightGBM classifier, a neural network classifier, etc., need to be established first. When the basic classifiers are trained, the training data of each basic classifier are the same, and finally, in order to improve the output precision of the classifier, all the basic classifiers are fused to form a final classifier.
Taking LightGBM as an example, the method of training the base classifier is: setting initial parameters such as learning rate, tree depth, tree leaf number, regularization parameters, iteration times and the like, inputting a training set into a model for fitting, and optimizing according to model evaluation indexes such as AUC, accuracy, recall rate and the like until the model converges.
The data sources for training the basic classifier are:
and extracting a positive sample of the rear link and a negative sample of the rear link, and obtaining the user characteristics of the positive sample of the rear link and the user characteristics of the negative sample of the rear link, wherein the positive sample data of the rear link is a customer with a stay action after full network combat and with a shop, test driving, ordering or success, the negative sample data of the rear link is a customer with a stay action after full network combat and without a shop, test driving, ordering or success, and the data sources are as described in S2.
And then processing the positive post-link samples and the negative post-link samples, extracting the user characteristics of the positive post-link samples and the positive post-link samples, and forming sample labels, specifically: useful features are extracted from the integrated data (the back-link positive samples and the back-link negative samples), including cues that include cue sources, customer information, interaction behavior, degree of intent, and the like. And then, carrying out preliminary screening on the extracted features, selecting features related to business and application scenes, finally determining the model entering features through methods such as feature selection, correlation analysis and the like, and finally carrying out feature extraction and sample label representation by adopting deep learning models such as convolutional neural networks and the like, wherein the sample label is numerical data including the age of a client, the browsing times of certain websites, consumption records and the like.
The thread itself in this embodiment will have a thread source, and the customer information, interaction, intent will be partially internal to the host factory itself, and partially derived from external data, e.g., the trisection will have a portion of customer representation data and purchased external data.
The features related to the business and application situations are selected in the embodiment, which features are related to the purchasing behavior are judged from the business angle, and then the features are screened and classified according to the relevance of the features and the labels.
The present embodiment divides the combination of the above-described processed features into a back link verification set and a back link training set for training each base classifier.
In order to avoid the risk of overfitting of a single complex model and improve the robustness of the model, a plurality of models in the second stage are fused, and a fused prediction result is output. Common fusion methods include a weighted average method, a voting method, a fusion network, a stacking method and the like, and considering the interpretability of the fusion method and whether subjective input is needed, the stacking method is finally adopted to fuse all basic classifiers, so that a final classifier is obtained.
The specific operation process of the fusion classifier is as follows: in the second stage, a plurality of basic classifiers including random forests, lightgbms, neural networks and the like are trained firstly, and after tuning is performed through a Q-Learning algorithm, the probability values of intention of a store/test driving/ordering/success are predicted by using the tuned plurality of basic models, and the probabilities of the store, test driving, ordering and success are generated by model fusion through a stacking method.
S4: and determining whether the customer has the intention of purchasing the vehicle conversion according to the probabilities of arriving at a store, trial driving, ordering and success behavior output by the final classifier. If so, the part of clients are followed.
In this embodiment, a reward function is set, where the independent variable is the probability of the behavior of arriving at a store, driving trial, ordering and delivering, and the dependent variable is the vehicle purchase conversion rate, and then the reward function is optimized by optimizing the weight values corresponding to the store, driving trial, ordering and delivering, and finally the optimized reward function is obtained. The output probability of arriving at the store, trial driving, ordering and bargaining is input into the optimized rewarding function, the vehicle purchase conversion rate is obtained, and the vehicle purchase conversion rate is segmented according to the value of the vehicle purchase conversion rate, and in the embodiment, if the probability is more than 0.8, the vehicle purchase conversion rate is 5 minutes, namely, the vehicle purchase conversion intention is high.
For example, the optimized reward function may determine the final purchase intent using a weighted average.
The method for optimizing the reward function comprises the following steps:
in the initial state, the weight values of the behaviors of arriving at a store, testing driving, placing orders and making deals are equal, and then the weight values of the behaviors of arriving at the store, testing driving, placing orders and making deals are optimized through a Q-Learning reinforcement Learning algorithm according to the output probability values of arriving at the store, testing driving, placing orders and making deals, and the specific steps are that:
firstly, assuming equal weights of four behaviors of store/test driving/ordering/bargaining, and constructing an initial rewarding function; the result of the underlying classifier is then combined with the strategy network Q-learning using a deep reinforcement learning approach for training and optimization. The method comprises the following specific steps:
(1) Defining a state: and taking the input sample label as a state.
(2) Defining actions: taking the output probability of the classifier as an action, wherein each category corresponds to one action.
(3) Defining a reward signal: the store-arriving, test-driving, ordering and deal behaviors are respectively defined as four reward signals, each reward signal is used as a mutually independent target, and the maximization of the overall vehicle purchase conversion rate is realized by weighing a plurality of targets of store-arriving, test-driving, ordering and deal.
(4) Determining weights of the bonus signals: the weight assigned to each bonus signal is initialized.
(5) Optimizing the weights of a plurality of targets, and finding a weight distribution scheme for optimizing the vehicle purchase conversion rate:
and continuously optimizing the weight by using a Q-Learning reinforcement Learning algorithm according to the initial weight of the rewarding signal, wherein the weight of the rewarding signal is used as a state, and the increase of the vehicle purchase conversion rate is rewarded.
And deciding whether to trigger the reward signal continuously or not according to the current state and the learned weight, and updating the weight.
Through continuous iteration, the algorithm gradually finds an optimal weight distribution scheme, and then an optimized reward function is obtained.
The flow of the Q-Learning algorithm is specifically used:
the initialization, wherein an expert method gives an initial weight (state), namely the weight proportion corresponding to the current target;
selecting an Action, namely changing the weight of a certain target;
triggering Reward, namely measuring the merits of the current decision by using a Reward function, and specifically: according to the current state and the action taken, a numerical value is obtained as a reward signal of each target, and a reward is obtained by calculation according to a reward function and is used for guiding the learning and optimizing process of the reinforcement learning algorithm.
