Overlap Removal of Dimensionality Reduction Scatterplot Layouts

Dimensionality Reduction (DR) scatterplot layouts have become a ubiquitous visualization tool for analyzing multidimensional data items with presence in different areas. Despite its popularity, scatterplots suffer from occlusion, especially when markers convey information, making it troublesome for users to estimate items' groups' sizes and, more importantly, potentially obfuscating critical items for the analysis under execution. Different strategies have been devised to address this issue, either producing overlap-free layouts, lacking the powerful capabilities of contemporary DR techniques in uncover interesting data patterns, or eliminating overlaps as a post-processing strategy. Despite the good results of post-processing techniques, the best methods typically expand or distort the scatterplot area, thus reducing markers' size (sometimes) to unreadable dimensions, defeating the purpose of removing overlaps. This paper presents a novel post-processing strategy to remove DR layouts' overlaps that faithfully preserves the original layout's characteristics and markers' sizes. We show that the proposed strategy surpasses the state-of-the-art in overlap removal through an extensive comparative evaluation considering multiple different metrics while it is 2 or 3 orders of magnitude faster for large datasets.Comment: 11 pages and 9 figure

CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines

Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

A pedagogical guide for teaching diatonic modality in the college music theory curriculum

Music theory plays a central role in the education of every college music major and minor. The typical undergraduate music theory core curriculum consists of a four- or five semester sequence of courses. As a result of the emphasis on traditional tonal harmony in Western music education, these core courses concentrate almost exclusively on the major/minor scalar system while marginalizing other types of scales such as diatonic modes. Common undergraduate theory textbooks that include the introduction of modality often only list the basic modal and scalar structures without offering further analysis and application; many other textbooks do not mention the term at all. This project addresses this curricular deficiency via the development of a sequential instructional program on diatonic modality for the undergraduate music theory curriculum. Applying a comprehensive musicianship approach, the project facilitates instruction that makes conceptual connections through listening, analysis, composition, and performance. The final product includes: A firm and broad pedagogical foundation for teaching diatonic modality in the undergraduate music theory curriculum—a research- and learning-theory-based foundation that supports the construction of the detailed scope and sequence. Three instructional principles in particular provide the foundation for the curriculum: sound before symbol, spiral learning, and comprehensive musicianship. A detailed curriculum guide for teaching diatonic modality in the undergraduate music theory core curriculum with a specific focus on the first two years of theory study: fundamentals, diatonic harmony, chromatic harmony, and 20th-century music theory. This includes specific pedagogical recommendations, a comprehensive scope and sequence delineated in three curriculum mapping tables, and thorough sequenced instructional guidelines for each step in the teaching-learning process. The 24 written theory and aural skills plans were specifically designed to be integrated throughout the typical four-semester curriculum. All of the plans are strongly activity-based and built around an extensive core of modal repertoire from all style periods including contemporary pop and jazz, emphasizing the authentic connection with music throughout history. If applied effectively, the innovative curriculum in this guide has the potential to not only significantly improve the teaching and learning of diatonic modality in undergraduate music theory but also to serve as a model that may help transform the overall approach to collegiate music theory instruction.Thesis (D.A.)School of Musi
