Enhanced Importance Sampling Through Latent Space Exploration in Normalizing Flows

AAAI 2025technical

Importance sampling is a rare event simulation technique used in Monte Carlo simulations to bias the sampling distribution towards the rare event of interest. By assigning appropriate weights to sampled points, importance sampling allows for more efficient estimation of rare events or tails of distr…

Safeguarding Learning-Based Planners Under Motion and Sensing Uncertainties Using Reachability Analysis

ICRA 2023poster

Learning-based trajectory planners in robotics have attracted growing interest given their ability to plan for complex tasks. These planners are typically trained in simulation under nominal conditions before being implemented on real robots. However, in real settings, the presence of motion and sen…
