Constants of Motion: The Antidote to Chaos in Optimization and Game Dynamics [article]

Georgios Piliouras, Xiao Wang
2021 arXiv   pre-print
Several recent works in online optimization and game dynamics have established strong negative complexity results including the formal emergence of instability and chaos even in small such settings, e.g  ...  We show how proving the existence of invariant functions, i.e., constant of motions, is a fundamental contribution in this direction and establish a plethora of such positive results (e.g. gradient descent  ...  Extensions Chaos in Learning and Games The first example of chaos in machine learning and game dynamics is introduced by [45], where the authors investigate the (non)convergence of multiplicative weights  ...

We then construct a quantum algorithm which uses the number of qubits in an optimal way and efficiently simulates a physical model with rich and complex dynamics.  ...  Various kinds of scaling laws are often observed in complex dynamical systems; for instance, SOC and punctuated equilibrium near the edge of chaos, 1/f spectrum, long time tails and anomalous diffusion  ...  We shall use both random matrix methods and correlation function techniques, as presented in the lectures of Dr. Prosen, to illuminate the problem at hand.  ...

THE PATTERN MAKING OF MEGA-SLUMS ON SEMANTICS IN SLUM URBAN CULTURES

A taxonomic tree of slums was developed to compare and map slum regions to describe similarities and differences among the selected case studies.  ...  Instead of surveying about stable urban symbols represented by formal orders and regular geometries, this study explores the semantic meaning of informal urbanism associated with chaos or randomness and  ...  They are the inevitable result of urban dynamics in constant transformation.  ...
