This full abstract describes our submitted systems for the MIREX09 audio classification tasks (genre, mood, classical composer, audio tagging) and music similarity and retrieval task. All the classification systems are based on basic acoustic features (e.g. MFCC) and the modeling framework of GSV-SVM, which has been successfully applied in speaker recognition field. And the similarity systems a...
Military personnel are commonly afflicted by lower extremity overuse injuries [1, 2]. Overuse knee conditions are among the most common injuries during basic training [3]. Walking with heavy loads is an inevitable part of the military training, and during the twelve-weeks of basic training, the loaded running and walking distance could exceed 200 miles [1]. Therefore, military personnel have to...
The Hausdorff distance is commonly used as a similarity measure between two point sets. Using this measure, a set X is considered similar to Y iff every point inX is close to at least one point in Y . Formally, the Hausdorff distance HAUSDIST(X,Y ) can be computed as the MAX-MIN distance from X to Y , i.e., find the maximum of the distance from an element in X to its nearest neighbor (NN) in Y ...
Missing values in data are common in real world applications. Since the performance of many data mining algorithms depend critically on it being given a good metric over the input space, we decided in this paper to define a distance function for unlabeled datasets with missing values. We use the Bhattacharyya distance, which measures the similarity of two probability distributions, to define ou...
Transport based distances, such as the Wasserstein distance and earth mover’s distance, have been shown to be an effective tool in signal and image analysis. The success of transport based distances is in part due to their Lagrangian nature which allows it to capture the important variations in many signal classes. However these distances require the signal to be nonnegative and normalized. Fur...
This paper reports on the utilization of synchronous information and communication technologies (ICT) in the delivery of distance education at the two largest public universities in Uganda. This was an exploratory descriptive survey that aimed at establishing the emerging issues in the utilization. Applying Peter’s theory of industrialization of distance education and Moore’s theory of transact...
Searching in a large data set those strings that are more similar, according to the edit distance, to a given one is a time-consuming process. In this paper we investigate the performance of metric trees, namely the M-tree, when they are extended using a cheap approximate distance function as a filter to quickly discard irrelevant strings. Using the bag distance as an approximation of the edit ...
Dempster-Shafer theory is widely applied in uncertainty modelling and knowledge reasoning due to its ability of expressing uncertain information. A distance between two basic probability assignments(BPAs) presents a measure of performance for identification algorithms based on the evidential theory of Dempster-Shafer. However, some conditions lead to limitations in practical application for Dem...
This paper discusses the basic philosophical assumptions of objectivism and constructivism including their implications for course design, interaction, and evaluation in distance education. First, I provide a brief overview of the construct of interaction as it is used in the field of distance education. Second, I address the major philosophical ideas of objectivism and constructivism as they r...
