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…

FIG-OP: Exploring Large-Scale Unknown Environments on a Fixed Time Budget

IROS 2022poster

We present a method for autonomous exploration of large-scale unknown environments under mission time con-straints. We start by proposing the Frontloaded Information Gain Orienteering Problem (FIG-OP) - a generalization of the traditional orienteering problem where the assumption of a reliable envir…

How Do We Fail? Stress Testing Perception in Autonomous Vehicles

IROS 2022poster

Autonomous vehicles (AVs) rely on environment perception and behavior prediction to reason about agents in their surroundings. These perception systems must be robust to adverse weather such as rain, fog, and snow. However, validation of these systems is challenging due to their complexity and depen…
