A Generalized Matrix Inverse that is Consistent with Respect to Diagonal Transformations
Jeffrey Uhlmann
A new generalized matrix inverse is derived which is consistent with respect to arbitrary nonsingular diagonal transformations, e.g., it preserves units associated with variables u…
Gaussianity and the Kalman Filter: A Simple Yet Complicated Relationship
Jeffrey Uhlmann, Simon Julier
One of the most common misconceptions made about the Kalman filter when applied to linear systems is that it requires an assumption that all error and noise processes are Gaussian.…
Achieving Unit-Consistent Pseudo-Inverse-based Path-Planning for Redundant Incommensurate Robotic Manipulators
Jacket Demby's, Jeffrey Uhlmann, Guilherme N. DeSouza
In this paper, we review and compare several velocity-level and acceleration-level Pseudo-Inverse-based Path Planning (PPP) and Pseudo-Inverse-based Repetitive Motion Planning (PRM…
Choosing the Correct Generalized Inverse for the Numerical Solution of the Inverse Kinematics of Incommensurate Robotic Manipulators
Jacket Demby's, Jeffrey Uhlmann, Guilherme N. DeSouza
Numerical methods for Inverse Kinematics (IK) employ iterative, linear approximations of the IK until the end-effector is brought from its initial pose to the desired final pose. T…
An Admissible Shift-Consistent Method for Recommender Systems
Tung Nguyen, Jeffrey Uhlmann
In this paper, we propose a new constraint, called shift-consistency, for solving matrix/tensor completion problems in the context of recommender systems. Our method provably guara…
Imposing Consistency Properties on Blackbox Systems with Applications to SVD-Based Recommender Systems
Tung Nguyen, Jeffrey Uhlmann
In this paper we discuss pre- and post-processing methods to induce desired consistency and/or invariance properties in blackbox systems, e.g., AI-based. We demonstrate our approac…
