We present a novel unsupervised artificial neural network for the extraction of common features in multiple data sources. This algorithm, which we name Exploratory Correlation Analysis (ECA), is a multi-stream extension of a neural implementation of Exploratory Projection Pursuit (EPP) and has a close relationship with Canonical Correlation Analysis (CCA). Whereas EPP identifies ”interesting” s...

Cover The words on the front and back cover pages have been ordered by letting MATLAB ® choose randomly and uniformly from a list of selected keywords. i Preface This PhD dissertation is based on a series of research projects conducted at The Royal Veterinary and Agricultural University (KVL), in the Chemometrics Research Group of Professor Lars Munck and colleagues during the period 1996-99. P...

Exploratory testing (ET) is a powerful and efficient way of testing software by integrating design, execution, and analysis of tests during a testing session. ET is often contrasted with scripted testing, and seen as a choice between black and white. We pose that there are different levels of exploratory testing from fully exploratory to fully scripted and propose a scale for the degree of expl...

The term “exploratory learning” usually denotes some type of activity used by students, with or without a teacher’s supervision, to facilitate the learning and mastery of a predefined and relatively circumscribed domain. That exploration may be more or less guided, according to the domain structure and the teacher's pedagogical goals and strategies. But there is also another way to use explorat...

Exploratory learning before instruction can benefit understanding, but can also be challenging. Individual differences in response to challenge, such as achievement motivation, may therefore moderate the benefits of exploratory learning. Higher mastery orientation generally leads to increased effort in response to challenge, whereas higher performance orientation leads to withdrawal. Children (...

Child and mother play (n = 113 20-month-olds) among South American Latino immigrants, Japanese immigrants, and European Americans in the United States was investigated. Culturally universal patterns of play dominated the findings. For example, no cultural differences in the prevalence of exploratory or symbolic play were found for either children or their mothers. Regardless of their culture, b...

There is a growing interest in model-based decision support under deep uncertainty, reflected in a variety of approaches being put forward in the literature. A key idea shared among these is the use of models for exploratory rather than predictive purposes. Exploratory modeling aims at exploring the implications for decision making of the various presently irresolvable uncertainties. This is ac...

Search engines are indispensable for locating information in WWW, but encounter great difficulties in handling exploratory information seeking, where precise keywords are hard to be formulated. A viable solution is to improve efficiency and quality of exploratory search by utilizing the wisdom of crowds (i.e., taking advantage of collective knowledge and efforts from a mass of searchers who sha...

In today’s world as our lives and livelihood depend largely on the software systems, malfunctioning of these software systems is highly intolerable. Hence, the delivery of high quality software becomes a big challenge for IT industries. However, various strategies are followed by IT industries to deliver a quality product within the estimated time and budget. Software Testing is one of these st...

Because exploratory rule discovery works with data that is only a sample of the phenomena to be investigated, some resulting rules may appear interesting only by chance. Techniques are developed for automatically discarding statistically insignificant exploratory rules that cannot survive a hypothesis with regard to its ancestors. We call such insignificant rules derivative extended rules. In t...
