An instrumental variable method for point processes: generalised Wald estimation based on deconvolution

2023 · arXiv (Cornell University)

Point processes are probabilistic tools for modeling event data. While there exists a fast-growing literature studying the relationships between point processes, it remains unexplored how such relationships connect to causal effects. In the presence of …

Robust Visual Sim-to-Real Transfer for Robotic Manipulation

2023

Learning visuomotor policies in simulation is much safer and cheaper than in the real world. However, due to discrepancies between the simulated and real data, simulator-trained policies often fail when transferred to real robots. One …
