In clustering, the evaluated distance metric is used to group data points together. Whereas, in KNN, this distance metric is used to find the K closest points to the given data point. In this article, we’ll review the properties of distance metrics and then look at the most commonly used...
Distance metrics are a key part of some machine learning algorithms, such as K-Nearest Neighbors KNN algorithm. Moreover, an effective distance metric can improve the performance of machine learning models, whether that's for classification tasks or clustering. In this project, we conducted ...
For instance, K-means, nearest-neighbors classi?ers and kernel algorithms such as SVMs all need to be given good metrics that re?ect reasonably well the important relationships between the data. This problem is particularly acute in unsupervised settings such as clustering, and is related to the...
Learning semantics-preserving distance metrics for clustering graphical data This motivates the need to learn such a metric. A technique called LearnMet is proposed here to learn a domain-specific distance metric for graphical ... AS Varde,EA Rundensteiner,C Ruiz,... - International Workshop on...
[46]. Furthermore, some online distance metrics learning algorithms [39,47]have been proposed re-cently for the situations where the data points are collected sequen-tially.The use of the learned distance metrics has been demonstrated in many real-word applications, including speech processing [48...
