This PR introduces Periodic and Parameterized Linear Expansion (PLE) numeric embeddings, along with an Advanced Combined Embedding layer. These new capabilities enhance KDP's performance on tabular tasks by providing sophisticated ways to model numerical features, aiming to close the performance gap between MLPs/Transformers and tree-based models.
The changes include:
