Stable Imitation of Multigait and Bipedal Motions for Quadrupedal Robots Over Uneven Terrains
Advanced Robotics Research, EarlyView.How are quadrupedal robots empowered to execute complex navigation tasks, including multigait and bipedal motions? Challenges in stability and real‐world adaptation persist, especially with uneven terrains and disturbances. This article presents an imitation learning framework that enhances adaptability and robustness by incorporating long short‐term ...

On Hahn-Banach theorem and some of its applications
Open Mathematics, 2022 First, this work provides an overview of some of the Hahn-Banach type theorems. Of note, some of these extension results for linear operators found recent applications to isotonicity of convex operators on a convex cone.

Estimating the spectral gap of a trace-class Markov operator
, 2019 The utility of a Markov chain Monte Carlo algorithm is, in large part, determined by the size of the spectral gap of the corresponding Markov operator. However, calculating (and even approximating) the spectral gaps of practical Monte Carlo Markov chains

Transfunctions Applied to Plans, Markov Operators and Optimal Transport
Annales Mathematicae SilesianaeA transfunction is a function which maps between sets of finite measures on measurable spaces. In this paper we characterize transfunctions that correspond to Markov operators and to plans; such a transfunction will contain the “instructions” common to ...

Fermionic duality: General symmetry of open systems with strong dissipation and memory
SciPost Physics, 2021 We consider the exact time-evolution of a broad class of fermionic open quantum systems with both strong interactions and strong coupling to wide-band reservoirs.

Markov uniqueness of degenerate elliptic operators [PDF]
, 2009 Let $\Omega$ be an open subset of $\Ri^d$ and $H_\Omega=-\sum^d_{i,j=1}\partial_i c_{ij} \partial_j$ a second-order partial differential operator on $L_2(\Omega)$ with domain $C_c^\infty(\Omega)$ where the coefficients $c_{ij}\in W^{1,\infty}(\Omega ...

Coupling methods for random topological Markov chains
, 2014 We apply coupling techniques in order to prove that the transfer operators associated with random topological Markov chains and non-stationary shift spaces with the big images and preimages-property have a spectral gap.Comment: 17 ...

Journal of Approximation Theory, 1976 AbstractIn this paper we consider iterates of Markov operators of the form Φf(x)=∑j=0mf(jmϕj(x) where the ϑj's are linearly independent, nonnegative and sum to 1. We define the evaluation matrix of Φ to be Φ∗ = [ϑj(im)] and prove that the iterates of the operator converge in the operator norm if and only if the powers of the evaluation matrix converge.

Advanced Robotics Research, EarlyView.This work presents a robotic control method for human–robot collaborative assembly based on a biomechanics‐constrained digital human model. Reinforcement learning is used to generate physiologically plausible human motion trajectories, which are integrated into a virtual environment for robot control learning.
