System and method for determining a transit prediction model
A method for prediction model determination can include: determining a set of models, training each model, determining package transit data, evaluating the set of models, selecting a model from the set of models, predicting package transit data using the selected model, and/or any other suitable element.
1. A system, comprising:
an interface configured to receive a request for a target package; and
a processing system configured to:
a) determine actual transit times for a set of packages;
b) train a set of models using supervised learning, wherein each model is associated with a sliding training window, wherein each model is trained using a different set of historic transit data, wherein training the set of models comprises training a set of model instances of each model, wherein each model instance is associated with a different reference date, wherein the set of historic transit data used to train the model instance is selected based on the sliding training window and the associated reference date;
c) for each model:
determine predicted transit times for the set of packages using the model; and
determine individual evaluation metrics for each of a set of time periods based on the predicted and actual transit times for the set of packages;
d) select a model from the set of models based on the individual evaluation metrics for each trained model; and
e) predict a transit time for the target package using the selected model;
wherein the interface returns the predicted transit time for the target package.
2. The system of claim 1 , wherein each of the set of packages is associated with an evaluation period, wherein each of the set of time periods is within the evaluation period.
3. The system of claim 1 , wherein each of the set of packages is delivered within the evaluation period.
4. The system of claim 1 , wherein the processing system is further configured to: for each model, aggregate the individual evaluation metrics to determine an overall evaluation metric, wherein selecting a model from the set of models based on the individual evaluation metrics comprises selecting the model based on the overall evaluation metric for each trained model.
5. The system of claim 1 , wherein predicting the transit time for the target package using the selected model comprises training a new model instance for the selected model, wherein the new model instance is associated with a reference date for the target package, wherein the transit time for the target package is predicted using the new model instance.
6. The system of claim 1 , wherein the reference date for the target package is determined based on a shipment creation date for the target package.
7. The system of claim 1 , wherein, for each model instance of a model, the sliding training window associated with the model slides with the reference date for the respective model instance.
8. The system of claim 1 , wherein the interface is further configured to return the predicted transit time for the target package, wherein the predicted transit time for the target package is used to select a shipping carrier service.
9. The system of claim 8 , wherein a label is generated for the selected shipping carrier service, wherein the target package is shipped using the label.
