A $(3+\varepsilon)$-Approximate Correlation Clustering Algorithm in Dynamic Streams [PDF]

TheoretiCS
Grouping together similar elements in datasets is a common task in data mining and machine learning. In this paper, we study streaming algorithms for correlation clustering, where each pair of elements is labeled either similar or dissimilar. The task is

On calculating the dimension of invariant sets of dynamic systems

Discrete and Continuous Models and Applied Computational Science
This work investigates numerical approaches for estimating the dimension of invariant sets onto which the trajectories of dynamic systems ``wind'', with a focus on fractal and correlation dimensions.

Dynamic SU(2) Lattice Gauge Theory at Finite Temperature

, 1997
The dynamic relaxation process for the (2+1)--dimensional SU(2) lattice gauge theory at critical temperature is investigated with Monte Carlo methods. The critical initial increase of the Polyakov loop is observed.

Event2Cor: Correlation Image Simulator for Dynamic Vision

IEEE Access
Event cameras asynchronously detect changes in light intensity with microsecond-level temporal resolution, offering rich motion information under dynamic scenes. However, the sparse and discrete nature of event streams hinder effective feature extraction

Dynamical networks from correlations

Physica A: Statistical Mechanics and its Applications, 2006
The extraction of relevant and meaningful information from large streams of data has become one of the major challenges for scientists working in the field of complex systems. In particular, one of the main goals is to get information about the underlying system of interactions that leads to complex collective dynamics.

The Dynamic Correlation Between Growth and Unemployment [PDF]

We apply the measure of dynamic correlation developed by Croux, Forni and Reichlin (2001) [A measure of comovement for economic variables: theory and empirics. Review of Economics and Statistics 83, 232-241] to the relation between the quarterly rates of
