Difference-Aware Retrieval Policies for Imitation Learning

Researchers present DARP, a semi-parametric retrieval-based approach to imitation learning that improves upon standard behavior cloning by predicting actions based on k-nearest neighbors from training data rather than learning a global policy. The method achieves 15-46% performance improvements across continuous control and robotic manipulation tasks without requiring additional data collection or expert feedback.

RowNet: A Memory Transformer for Tabular Regression

RowNet is a neural architecture that improves real estate price prediction by using memory-based retrieval to identify comparable properties rather than treating each property in isolation. The model combines similarity matching, attention mechanisms, and mixture-of-experts to outperform traditional multilayer perceptrons and gradient-boosted decision trees on tabular regression tasks.
