Randomized geometric tools for anomaly detection in stock markets

AISTATS 2023poster

We propose novel randomized geometric tools to detect low-volatility anomalies in stock markets; a principal problem in financial economics. Our modeling of the (detection) problem results in sampling and estimating the (relative) volume of geodesically non-convex and non-connected spherical patches…

GPU-Based Homotopy Continuation for Minimal Problems in Computer Vision

CVPR 2022poster

Systems of polynomial equations arise frequently in computer vision, especially in multiview geometry problems. Traditional methods for solving these systems typically aim to eliminate variables to reach a univariate polynomial, e.g., a tenth-order polynomial for 5-point pose estimation, using cl…

TRPLP - Trifocal Relative Pose From Lines at Points

CVPR 2020poster

We present a method for solving two minimal problems for relative camera pose estimation from three views, which are based on three view correspondences of (i) three points and one line and (ii) three points and two lines through two of the points. These problems are too difficult to be efficiently…
