When Tabular Foundation Models Meet Strategic Tabular Data: A Prior Alignment Approach
The paper discusses the challenges faced by tabular foundation models in strategic data environments. It introduces a new framework, Strategic Prior-data Fitted Network (SPN), designed to adapt these models to post-deployment feature manipulations. Experimental results demonstrate that SPN enhances predictive performance and robustness compared to traditional methods.
- ▪Tabular foundation models typically operate under non-strategic settings where data distributions are independent of classifiers.
- ▪Strategic manipulation of features can lead to a mismatch between pre-trained models and actual post-manipulation data distributions.
- ▪The proposed SPN framework allows for adaptation to strategic environments without the need for retraining.
