We propose a general approach for frequency based string mining, which has
many applications, e.g. in contrast data mining. Our contribution is a novel
algorithm based on a deferred data structure. Despite its simplicity, our approach
is up to 4 times faster and uses about half the memory compared to the best-
known algorithm of Fischer et al. Applications in various string domains, e.g.
natural language, DNA or protein sequences, demonstrate the improvement of
our algorithm.

In this chapter, we compare two contrast set mining methodologies that rely on
different statistical philosophies: the well-known STUCCO approach and CIGAR,
our proposed alternative approach. Following a brief introduction to general
issues and problems related to statistical hypothesis testing in data mining, we
survey and discuss the statistical measures underlying the two methods using an
informal tutorial approach. Experimental results show that both methodologies
are ...

This paper proposes a new denoising diffusion model for fluorescence
microscopic images, in which fourth-order partial differential equations (PDEs)
and contrast enhancement are utilized to overcome the blocky effect and false
edges usually caused by second-order PDEs. Experimental results show that the
proposed method not only makes the denoised images subjectively natural and
clear, but also achieves better performance in terms of objective criterion such as
peak signal to ...

In the previous Chapters, we focused on data mining methods for analysis and
extraction of useful knowledge from structured data such as flat file, relational,
transactional, and data warehouse data. In contrast, in this Chapter we are
concerned with the analysis of text databases that consist of mainly
semistructured or unstructured data. Text databases usually consist of collections
of articles, research papers, e-mails, blogs, discussion forums, and web pages.
With the rapid growth of ...

Alex A. Freitas University of Kent, UK, Computing Laboratory, ... The motivation
for applying EAs to data mining is that they are robust, adaptive search
techniques that perform a global search in the solution space. This chapter first
presents a brief ... In contrast, several more conventional data mining methods
perform a local, greedy search in the space of candidate solutions. As a result of
their global ...

High- throughput technologies in genomics and proteomics generate myriads of
intricate data, and the analysis of these data presents unprecedented analytical
and computational challenges. On one hand, because of ethical, cost and time
constraints involved in running experiments, most life science studies include a
modest number of cases (i.e., samples), n. Typically, n ranges from several dozen
to several hundred. This is in stark contrast with conventional data mining ...

Chapter 6 SEARCHING FOR BENT-DOUBLE GALAXIES IN THE FIRST SURVEY
Chandrika Kamath, Erick Cantii-Paz, Imola K. Fodor, and Nu Ai Tang Abstract
Data mining techniques are increasingly gaining popularity in various scientific
domains as viable approaches to the analysis of massive data sets. In this
chapter, we ... We explain why, in contrast with most commercial data mining
applications, data preprocessing requires a considerable effort in scientific
applications.
