Jev 动作选择模型在支付欺诈检测中的初步测试

作者试用新的 Jev 动作选择模型,认为其不太可能取代支付欺诈检测,因为许多特征为表格数据,表现不及 LightGBM,但考虑到该场景可能并非其目标用例,结果已令人印象深刻。

Time to start playing with #jev the new action selection model. Will it replace Fraud detection for payment. Well unlikely because a lot of the features are tabular. Underperforming a Lightgbm but it it already impressive given that this probably not the use case for it.
