It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

The embodiment of the invention provides a method for constructing a cargo quantity prediction model, which can comprise the following steps of:

s11, obtaining identification information of a plurality of areas and historical cargo quantity information corresponding to the areas. As an exemplary embodiment, the area is a range for acquiring the cargo volume data, for example, may be a certain location, and may be, for example, an address of a discharge location or a loading location, or may be a range within a certain radius centering on the certain location, and may be, for example, an address of a discharge location or a loading location centering on the certain location, and a range within a radius of 30KM as an area, or may be divided into areas by an administrative area where the certain location is located, and may be, for example, a city, an administrative district, a county, or the like where the address of the discharge location or the address of the loading location is located. It should be noted that the address referred to in this embodiment includes the exemplary listed areas, and may also include other customized areas or areas with wider or narrower ranges.

The historical cargo volume information referred to as corresponding to a region may historically yield cargo traffic information for that region. In this embodiment, a city may be taken as an area for explanation: the historical cargo quantity information may be the cargo quantity information of a certain city in a historical preset time period as the historical cargo quantity information of the area, for example, the cargo quantity information of a certain city taken out of the city generated on a certain historical day of the area may be the historical cargo quantity information of the area, the cargo quantity information of a certain city taken out of the city generated on a certain historical day of the city may be the historical cargo quantity information of the area, or the cargo quantity information of a certain city taken out of the city generated on a certain historical time period of the city may be the historical cargo quantity information of the area; in addition, the cargo amount information may also be the cargo amount information carried into the area, or may be the sum of the cargo amount information carried into and out of the area. It should be understood by those skilled in the art that the amount information referred to in the present embodiment is within the scope of the present embodiment as long as the data reflecting the amount of goods, such as the amount of orders, the weight of the goods, the number of the goods, etc., can be obtained.

Note that the plurality of regions means two or more regions.

And S12, inputting the identification information and the historical cargo quantity information serving as training samples into the prediction model to be trained, and training the prediction model to be trained to obtain the trained prediction model. In the present embodiment, the prediction model to be trained may include one of a Lasso model, an Xgboost model, a Lightgbm model, and a Prophet model, or a combination of at least any two of them, and those skilled in the art should understand that the prediction model in the present embodiment may also be other models. The specific training method may be training according to a training method of an existing model, and the training method is not limited in this embodiment.

It should be noted that, when the identification information and the historical cargo quantity information are used as training samples to train the model to be trained, the cargo quantity information of a certain area in a certain time period in the history can be used as the training samples of the model to be trained. The same model to be trained is trained simultaneously based on the cargo capacity information of a plurality of regions in a certain historical time period, so that the trained prediction model has a multi-region cargo capacity prediction function. As an alternative embodiment, the historical cargo quantity information and the identification information may be combined to form data in a specific format as a training sample. Therefore, in the cargo quantity prediction, the cargo quantities of different areas can be predicted in one prediction model.

When the goods quantity is predicted, an artificial intelligence prediction model is adopted for prediction, and training samples are identification information of a plurality of areas and historical goods quantity information corresponding to the areas when the model is trained, so that the trained prediction model can predict the goods quantity information of a plurality of places, a plurality of prediction models do not need to be built aiming at different places, the complexity of building the prediction model can be effectively reduced, in addition, the sample quantity can be effectively increased by training the same model by adopting the identification information of the plurality of areas and the historical goods quantity information of the plurality of areas, the recognition precision of the prediction model is improved, and the problems that an independent prediction model is independently built aiming at one place or area in the prior art, and the model prediction precision cannot be improved under the condition of limited historical goods quantity data can be effectively solved.

As an exemplary embodiment, the identification information of the region may be prepared before training the prediction model, for example, an identification code established for characterizing the region based on a preset rule is used as the identification information, which is not specifically limited in this embodiment. The identification information of the regions may also respectively establish identification information for distinguishing the regions based on a preset rule, specifically, the regions are described by taking cities as examples, for example, historical freight data of 10 cities, such as shenzhen city, huizhou city, kunshan city, suzhou city, nanjing city, elchun city, spring city, zhangyang city and harrisun city, are input, except for the historical freight volume information of the 10 cities, the identification information of the 10 cities needs to be input, where the identification information may be names of the cities (names of the regions), or area codes corresponding to the cities (standard codes corresponding to the regions), or numbers for distinguishing the 10 cities by themselves, and the like, for distinguishing each region.

Exemplarily, establishing the identification code for characterizing the region based on the preset rule may be performed by the following means, specifically, obtaining the number N of the regions; and establishing N-dimensional vector codes which correspond to the regions one by one on the basis of the number N of the regions as identification codes of the regions. Taking 10 cities as an example in the above embodiment, the vector code may be 10-dimensional vector codes, each corresponding to one region, for example:

shenzhen city {1,0,0,0,0,0,0,0, 0}

Huizhou city {0,1,0,0,0,0,0,0,0,0}

Kunshan city {0,0,1,0,0,0,0,0,0,0}

Suzhou city {0,0,0,1,0,0,0,0, 0}

Nanjing city {0,0,0,0,1,0,0,0,0,0}

Islands {0,0,0,0,0,1,0,0,0,0}

Spring city {0,0,0,0,0,0,1,0,0,0}

Zhangye City {0,0,0,0,0,0,0,1,0,0}

Luoyang city {0,0,0,0,0,0,0,0,1,0}

Harbin City {0,0,0,0,0,0,0,0,0,1 }. To improve the accuracy of the prediction model, regions may be associated to make the results output by the prediction model more accurate. For example, the area association relationship is used to perform embedded expression on the identification code established based on the preset rule and used for representing the area to obtain data as the identification information. As an alternative embodiment, the areas may be associated based on the behavior data, and the area association relationship is, for example, a relationship between areas established when the same user or a certain user group generates a behavior related to freight transportation.

Specifically, behavior data related to freight transportation of the same user or a certain specific user group can be acquired; identifying a plurality of regions contained in the behavioral data; and associating a plurality of areas contained in the behavior data to obtain an area association relation. The regions are correlated based on the behavior data, so that the input data can be more converged before being predicted, and the model prediction accuracy is improved.

The association of the regions based on the region association relationship obtained from the behavior data may be a sequence relationship between regions established when the same user or a certain group of users consults, browses, places orders, carries, and the like, in relation to freight. For example, in the process of browsing the freight orders, each user may search for an order that the user needs, in the action process, an area in which the user wants to take over the order is limited, and in the process of browsing the freight orders twice in the front and back of the user, the two freight orders may include two different area information, but the two area information may be the area in which the user wants to take over the freight orders, so that the action of the user establishes an association between the two different areas. Besides, the user can also establish the association relationship between the areas in the process of ordering, transporting and other actions.

As an exemplary embodiment, in order to prevent the input information of model training from being too sparse and poor in training effect due to too many regions, in this embodiment, the input information may be embedded and represented by using a region association relationship, so as to reduce the sparsity of training samples, improve the training effect of the model, and further improve the prediction accuracy of the model. In this embodiment, the identification information may be N-dimensional vector codes or may be information in other forms, for example: the name of the city, or the area code or custom code corresponding to the city. In this embodiment, the identification information may be N-dimensional vector codes as an example for explanation:

by using the region association relations, N-dimensional vector codes of N regions can be embedded and expressed. The process of the embedded representation may use the existing method, and is not limited in this application.

For example, the identification information after embedded representation by using the area association relationship may be:

shenzhen city { -0.77,0.31, -0.12}

Huizhou city { -0.76,0.33, -0.13}

Kunshan city { -0.61,0.39,0.17}

Suzhou city { -0.61,0.41,0.15}

Nanjing City { -0.62,0.43,0.15}

Islands' 0.16,0.17,0.68}

Spring city {0.22,0.78, -0.11}

Zhangye City {0.21,0.77, -0.12}

Luoyang city {0.51, -0.51, -0.52}

Harbin City {0.15,0.15,0.65 }.

After the embedded representation is completed, for example, the embedded vector coding is used for replacing a plurality of N vector codes as the identification information of the region, and the identification information of the region can be embodied in a lower dimension, so that the problems that the input information is too sparse, the training effect is poor, and the accuracy of the output result of the prediction model is not high can be prevented.

An embodiment of the present invention provides a method for predicting a cargo volume, as shown in fig. 2, the method may include the following steps:

and S21, acquiring identification information of the area to be predicted and historical cargo quantity information corresponding to the area to be predicted. In the present embodiment, the acquired identification information of the region should coincide with the identification information of the region used when the model is built. The specific method for acquiring the identification information of the area may refer to the description in the above embodiments. The historical cargo quantity information also needs to be the same as the historical preset interval period used in the modeling, and in particular, the description of the historical cargo quantity information can be summarized by referring to the above embodiment.

And S22, inputting the historical cargo quantity information of the area to be predicted and the area to be predicted into a prediction model to obtain the predicted cargo quantity of the area to be predicted. Specifically, the prediction model may be constructed by using the method for constructing the cargo capacity prediction model in the above embodiment.

After the prediction model is built, identification information of an area and specific historical data can be input into the prediction model, and the needed goods amount can be calculated by using the prediction model. In addition, the identification information of the inputted area should be identical to the identification information of the area used when the model is built, and the historical cargo amount information also needs to be identical to the historical preset interval period used when the model is built.

For example, the following can be illustrated by taking the example of predicting the cargo capacity of a certain city, such as Shenzhen city: when the prediction model is built, the identification information of Shenzhen city is { -0.77,0.31, -0.12}, and when the cargo capacity of Shenzhen city is predicted, the identification information of the region input into the prediction model should also be { -0.77,0.31, -0.12}, but {1,0,0,0,0,0,0,0,0,0}, or a region code and the like cannot be input into the prediction model. If the forecasting model is established, historical cargo quantity information of the time T is used as input, and the cargo quantity information of the time T is used as output to be trained, namely, the cargo quantity data of the third day, the fourth day and the fifth day before the time T are used as input. Then historical inventory information for T-3, T-4, T-5 may also be required as input in the prediction. For example, the time is 2/5/2020, and it is desired to predict the data of the volume of Shenzhen city in 2/6/2020, then the data of the volume of Shenzhen city in three days, i.e. 2/1/2020, 2/2020, and 2/3/2020, need to be input at this time.

When the goods quantity is predicted, an artificial intelligence prediction model is adopted for prediction, and during model training, training samples are identification information of a plurality of areas and historical goods quantity information corresponding to the areas, so that the trained prediction model can predict the goods quantity information of a plurality of places, a plurality of prediction models do not need to be built aiming at different places, the complexity of building the prediction model can be effectively reduced, in addition, the number of samples can be effectively increased by training the same model by adopting the historical goods quantity information of the plurality of areas and the plurality of areas, the recognition precision of the prediction model is improved, and the problems that the independent prediction model is separately built aiming at one place or area and the model prediction precision cannot be improved under the condition that the goods quantity data is limited in the prior art can be effectively solved.
