TabKANet: Tabular Data Modelling with Kolmogorov-Arnold Network and Transformer

Tabular data is the most common type of data in real-life scenarios. In this study, we propose a method based on the TabKANet architecture, which utilizes the Kolmogorov-Arnold network to encode numerical features and merge them with categorical features, enabling unified modeling of tabular data on the Transformer architecture. This model demonstrates outstanding performance in six widely used binary classification tasks, suggesting that TabKANet has the potential to become a standard approach for tabular modeling, surpassing traditional neural networks. Furthermore, this research reveals the significant advantages of the Kolmogorov-Arnold network in encoding numerical features.
