We use two rounds of surveys, in 2000 and 2008, in the Zhili Township children’s garment cluster in Zhejiang Province to examine in depth its evolution. Firm size has grown on average in terms of outp...
We use two rounds of surveys, taken in 2000 and 2008 in the Zhili Township children’s garment cluster in Zhejiang Province, to examine in depth the evolution of this industrial cluster. Firm size has ...
Evolution of Covariance Functions for Gaussian Process Regression using Genetic Programming
Gaussian Process Genetic Programming Structure Identification
2013/6/14
In this contribution we describe an approach to evolve composite covariance functions for Gaussian processes using genetic programming. A critical aspect of Gaussian processes and similar kernel-based...

An ongoing debate in evolutionary biology is whether phenotypic change occurs predominantly around the points of speciation or does it accumulate gradually over time. In this work we propose a general...
Measuring the likelihood of models for network evolution
Measuring the likelihood models network evolution
2013/4/28
Many researchers have hypothesised models which explain the evolution of the topology of a target network. The framework described in this paper gives the likelihood that the target network arose from...
Preserving User Preferences in Automated Document-Category Management: An Evolution-Based Approach

2011/10/7
Analysis of prevalent document management practices shows the popular use of categories (e.g., folders) to organize documents for subsequent searches and retrievals. The coherence and distinction of a...
Evolution of the CMB Power Spectrum Across WMAP Data Releases: A Nonparametric Analysis
Cosmic microwave background (CMB) angular power spectrum
2011/7/19
We present a comparative analysis of the WMAP 1-, 3-, 5-, and 7-year data releases for the CMB angular power spectrum, with respect to the following three key questions: (a) How well is the angular po...
Co-evolution of Selection and Influence in Social Networks
Co-evolution Selection Influence Social Networks
2011/7/7
Many networks are complex dynamical systems, where both attributes of nodes and topology of the network (link structure) can change with time. We propose a model of co-evolving networks where both nod...
This paper presents Natural Evolution Strategies (NES), a recent family of algorithms that constitute a more principled approach to black-box optimization than established evolutionary algorithms.

Reassessing The Fundamentals: New Constraints on the Evolution, Ages and Masses of Neutron Stars
neutron —pulsars general —X-rays binaries —stars statistics
2011/3/25
The ages and masses of neutron stars (NSs) are two fundamental threads that make pulsars accessible to other sub-disciplines of astronomy and physics. A realistic and accurate determination of these t...
THE EVOLUTION OF INCOME CONCENTRATION IN JAPAN, 1886-2002: EVIDENCE FROM INCOME TAX STATISTICS
INCOME CONCENTRATION JAPAN INCOME TAX STATISTICS
2010/11/5
This paper studies the evolution of income concentration in Japan from 1886 to 2002 by constructing long-run series of top income shares and top wage income shares, using income tax statistics. We fin...
