The invention relates to the technical field of e-commerce, and discloses a cross-border e-commerce abnormal
order processing method and
system based on
reinforcement learning, and the method comprises the steps: collecting historical transaction records and real-time behavior records of a user, and obtaining an
original data set; performing format unification according to the
original data set to obtain a structured
data set, and performing multi-dimensional
feature extraction to obtain multi-dimensional behavior features; according to the multi-dimensional behavior characteristics, abnormal
sequence analysis and
risk level classification are carried out, and
risk control adjustment parameters are matched; according to the
risk control adjustment parameters and the structured
data set, environment grouping, risk order identification and abnormal
feature extraction are carried out to obtain
abnormal distribution features; according to the
abnormal distribution characteristics, comprehensive risk analysis is carried out through a pre-constructed neural
network model, and a comprehensive risk
score is obtained; and performing abnormal order judgment and
risk control processing according to the comprehensive risk
score and the historical transaction
record, and optimizing a neural
network model. The method improves the accuracy of abnormal order detection.
