TabKD: Tabular Knowledge Distillation through Interaction Diversity of Learned Feature Bins
Researchers have developed a new method called TabKD for data-free knowledge distillation in tabular domains. This technique addresses the limitations of existing methods by focusing on feature interactions, which are crucial for how tabular models learn predictive knowledge. TabKD works by creating adaptive feature bins that align with the teacher model's decision boundaries and then generating synthetic data to maximize the coverage of pairwise feature interactions. Experiments on benchmark datasets show that TabKD significantly outperforms state-of-the-art baselines in student-teacher agreement and demonstrates a strong correlation between interaction coverage and distillation quality.
