The invention relates to the field of
data processing, and provides a cross-border e-commerce intelligent
product selection system and method based on multi-platform data fusion, and the method comprises the steps: carrying out the data collection and preprocessing of a plurality of cross-border e-commerce platforms, constructing a neural
network model through optimal hyper-parameters, training, and generating a selected product recommendation
list. Meanwhile, the structural parameters and the search direction of the selected
product model are continuously updated, and the selected product recommendation
list is dynamically updated. According to the
system, multi-platform commodity data are integrated, versioning feature snapshots are constructed, hyper-parameter selection of a multi-snapshot version
evaluation strategy optimization model with a consistent
time sequence is adopted, the generalization ability of a commodity selection model to a time-varying data environment is enhanced, the possibility that the accuracy of the model is reduced due to the change of data distribution is reduced, and the accuracy of the commodity selection model is improved. Meanwhile, dynamic updating of the selected product recommendation
list is achieved, and it is ensured that the recommendation strategy can be fully matched with preference migration of the selected product trend.
