This thesis deals with methods and techniques for music exploration, mainly focussing on the task of music retrieval. This task has become an important part of the modern music society in which music is distributed effectively via for example the Internet. This calls for automatic music retrieval and general machine learning in order to provide organization and navigation abilities. This Master...

Based on CART, we introduce a recursive partitioning method for high dimensional space which partitions the data using low dimensional features. The low dimensional features are extracted via an exploratory projection pursuit (EPP) method, localized to each node in the tree. In addition, we present an exploratory splitting rule that is potentially less biased to the training data. This leads to...

Online search has become an increasingly important part of the everyday lives of most computer users. Generally, popular search tools support users well, however, in situations where the search problem is poorly defined, or the information seeker is unfamiliar with the problem domain, or the search task requires some exploration or the consideration of multiple perspectives, such tools may not ...

Exploratory information seeking in a knowledge domain, especially in an interdisciplinary area, with the purpose of learning and getting a sense of the domain is a challenge that new researchers are constantly facing. To address this challenge, we suggest a new visualization-based approach for collaborative exploratory information seeking. First, we introduce ExplorationMap, which is a node-lin...

We evaluate the effectiveness of a tutorial-dialogue based approach to guided exploratory learning involving problem solving goals that are negotiated between tutor and student rather than dictated by the tutor or freely chosen by the student. This approach, referred to as Negotiable Problem Solving Goals (NPSG), is located on a previously untested space on what we call The Exploratory Learning...

This paper argues that sequences of exploratory drawings constructed by designer’s movements and decisions trace systematic and logical paths from ideas to designs. This argument has three parts. First, sequences of exploratory sketches produced by product designers, against the same task specification, are analyzed in terms of the cognitive categories of reinterpretation, emergence and abstrac...

Gradient-following algorithms are deployed for efficient adaptation of exploration parameters in temporal-difference learning with discrete action spaces. Global and local variants are evaluated in discrete and continuous state spaces. The global variant is memory efficient in terms of requiring exploratory data only for starting states. In contrast, the local variant requires exploratory data ...

an 8-month-old female thoroughbred foal was presented showing signs of colic. the foal was anxious,exhibiting signs of abdominal pain and distention. the foal had tachycardia (120 beats/min), tachypnea (40breaths/min). blood samples obtained for haematologic and serum biochemistry analysis that showed a pcvof 30% and a tpp of 70 g/l. the peritoneal fluid analysis revealed a clear fluid with mil...

In this paper we evaluate the instructional effectiveness of tutorial dialogue agents in an exploratory learning setting. We hypothesize that the creative nature of an exploratory learning environment creates an opportunity for the benefits of tutorial dialogue to be more clearly evidenced than in previously published studies. In a previous study we showed an advantage for tutorial dialogue sup...

People intuitively use search engines to look for health information. However, people take an exploratory search approach to find the information in some scenarios, and current search engines do not support these cases well. This exploratory information seeking behaviour is rarely investigated by researchers in the context of online consumer health information. We report on a qualitative study ...
