Cluster Size Management in Multi-Stage Agglomerative Hierarchical Clustering of Acoustic Speech Segments
Lerato Lerato, Thomas Niesler
Agglomerative hierarchical clustering (AHC) requires only the similarity between objects to be known. This is attractive when clustering signals of varying length, such as speech,…

Feature Trajectory Dynamic Time Warping for Clustering of Speech Segments
Lerato Lerato, Thomas Niesler
Dynamic time warping (DTW) can be used to compute the similarity between two sequences of generally differing length. We propose a modification to DTW that performs individual and…

Comparison of the Performance of Two Service Disciplines for a Shared Bus Multiprocessor with Private Caches
Angel Vassilev Nikolov, Lerato Lerato
In this paper, we compare two analytical models for evaluation of cache coherence overhead of a shared bus multiprocessor with private caches. The models are based on a closed queu…
