Entropy and the Complexity of Graphs Revisited

  • Abbe Mowshowitz and
  • Matthias Dehmer

14 March 2012

This paper presents a taxonomy and overview of approaches to the measurement of graph and network complexity. The taxonomy distinguishes between deterministic (e.g., Kolmogorov complexity) and probabilistic approaches with a view to placing entropy-b...

Curvature Entropy for Curved Profile Generation

  • Yoshiki Ujiie,
  • Takeo Kato,
  • Koichiro Sato and
  • Yoshiyuki Matsuoka

9 March 2012

In a curved surface design, the overall shape features that emerge from combinations of shape elements are important. However, controlling the features of the overall shape in curved profiles is difficult using conventional microscopic shape informat...

Minimum Error Entropy Filter for Fault Detection of Networked Control Systems

  • Jianhua Zhang,
  • Lilong Du,
  • Mifeng Ren and
  • Guolian Hou

6 March 2012

In this paper, fault detection of networked control systems with random delays, packet dropout and noises is studied. The filter is designed using a minimum error entropy criterion. The residual generated by the filter is then evaluated to detect fau...

Interval Entropy and Informative Distance

  • Fakhroddin Misagh and
  • Gholamhossein Yari

2 March 2012

The Shannon interval entropy function as a useful dynamic measure of uncertainty for two sided truncated random variables has been proposed in the literature of reliability. In this paper, we show that interval entropy can uniquely determine the dist...

The Mathematical Structure of Information Bottleneck Methods

  • Tomáš Gedeon,
  • Albert E. Parker and
  • Alexander G. Dimitrov

1 March 2012

Information Bottleneck-based methods use mutual information as a distortion function in order to extract relevant details about the structure of a complex system by compression. One of the approaches used to generate optimal compressed representation...
