Learning Invariant Object and Spatial View Representations in the Brain Using Slow Unsupervised Learning

open access: yesFrontiers in Computational Neuroscience, 2021
First, neurophysiological evidence for the learning of invariant representations in the inferior temporal visual cortex is described. This includes object and face representations with invariance for position, size, lighting, view and morphological ...

A note on the convergence of parametrised non-resonant invariant manifolds

open access: yes, 2010
Truncated Taylor series representations of invariant manifolds are abundant in numerical computations. We present an aposteriori method to compute the convergence radii and error estimates of analytic parametrisations of non-resonant local invariant ...

On lacunary I-invariant arithmetic convergence

open access: yesMalaya Journal of Matematik, 2021
In this study, we investigate the notion of lacunary $\mathcal{I}_{\sigma }$ arithmetic convergence for real sequences and examine relations between this new type convergence notion and the notions of\ lacunary invariant arithmetic summability, lacunary strongly $q$-invariant arithmetic summability and lacunary $\sigma $-statistical arithmetic ...

Lyapunov Stability Analysis for Invariant States of Quantum Systems

open access: yes, 2018
In this article, we propose a Lyapunov stability approach to analyze the convergence of the density operator of a quantum system. In contrast to many previously studied convergence analysis methods for invariant density operators which use weak ...

Unimodular Random Trees [PDF]

open access: yes, 2012
We consider unimodular random rooted trees (URTs) and invariant forests in Cayley graphs. We show that URTs of bounded degree are the same as the law of the component of the root in an invariant percolation on a regular tree.

Global dynamics of an exponential system by a discrete-time Lyapunov function

open access: yesJournal of Taibah University for Science, 2020
In this paper, we explore the boundedness and persistence of positive solution, existence as well as uniqueness of positive equilibrium point, existence of invariant rectangle, local and global dynamics, and rate of convergence of three-directional ...

New Iterative Learning Control Algorithm Using Learning Gain Based on σ Inversion for Nonsquare Multi-Input Multi-Output Systems

open access: yesModelling and Simulation in Engineering, 2018
Model inversion Iterative Learning Control (ILC) for a class of nonsquare linear time variant/invariant multi-input multi-output (MIMO) systems is considered in this paper. A new ILC algorithm is developed based on σ-right inversion of nonsquare learning

The Gauss Constraint in the Extended Loop Representation [PDF]

open access: yes, 1996
The Gauss constraint in the extended loop representation for quantum gravity is studied. It is shown that there exists a sector of the state space that is rigorously gauge invariant without the generic convergence issues of the extended holonomies ...

The Convergence of Double-Indexed Weighted Sums of Martingale Differences and Its Application

open access: yesAbstract and Applied Analysis, 2014
We investigate the complete moment convergence of double-indexed weighted sums of martingale differences. Then it is easy to obtain the Marcinkiewicz-Zygmund-type strong law of large numbers of double-indexed weighted sums of martingale differences ...
