Expected Transaction Value Optimization for Precise Marketing in FinTech Platforms

no code implementations3 Jan 2024 Yunpeng Weng, Xing Tang, Liang Chen, Dugang Liu, Xiuqiang He

In addition to predicting the click-through rate (CTR) or the conversion rate (CVR) as in traditional recommendations, it is essential for FinTech platforms to estimate the customers' purchase amount for each delivered fund and achieve an effective allocation of impressions based on the predicted results to optimize the total expected transaction value (ETV).

OptMSM: Optimizing Multi-Scenario Modeling for Click-Through Rate Prediction

no code implementations23 Jun 2023 Xing Tang, Yang Qiao, Yuwen Fu, Fuyuan Lyu, Dugang Liu, Xiuqiang He

Existing approaches for multi-scenario CTR prediction generally consist of two main modules: i) a scenario-aware learning module that learns a set of multi-functional representations with scenario-shared and scenario-specific information from input features, and ii) a scenario-specific prediction module that serves each scenario based on these representations.

Explicit Feature Interaction-aware Uplift Network for Online Marketing

no code implementations1 Jun 2023 Dugang Liu, Xing Tang, Han Gao, Fuyuan Lyu, Xiuqiang He

Our EFIN includes four customized modules: 1) a feature encoding module encodes not only the user and contextual features, but also the treatment features; 2) a self-interaction module aims to accurately model the user's natural response with all but the treatment features; 3) a treatment-aware interaction module accurately models the degree to which a particular treatment motivates a user through interactions between the treatment features and other features, i. e., ITE; and 4) an intervention constraint module is used to balance the ITE distribution of users between the control and treatment groups so that the model would still achieve a accurate uplift ranking on data collected from a non-random intervention marketing scenario.

Curriculum Modeling the Dependence among Targets with Multi-task Learning for Financial Marketing

no code implementations25 Apr 2023 Yunpeng Weng, Xing Tang, Liang Chen, Xiuqiang He

For example, in online marketing, the cascade behavior pattern of $impression \rightarrow click \rightarrow conversion$ is usually modeled as multiple tasks in a multi-task manner, where the sequential dependence between tasks is simply connected with an explicitly defined function or implicitly transferred information in current works.
