In this chapter we present several machine learning algorithms for clustering. Besides the utilization of clustering in grouping unlabeled data, it can be used for feature extraction technique as well. We discuss in detail the application of these algorithms in different fields.doi:10.1016/B978-0-12-821379-7.00007-2Abdulhamit SubasiPractical Machine Learning for Da...

HAC’s account for the vast majority of hierarchical clustering algorithms. However, one downside is that they havesignificant computational and storage requirements— especially for big data. These complex algorithms are about quadruple the size of theK-means algorithm. Also, merging can’t be revers...
The basic idea behind k-means clustering consists of defining clusters so that the total intra-cluster variation (known as total within-cluster variation) is minimized. There are several k-means algorithms available. The standard algorithm is the Hartigan-Wong algorithm (Hartigan and Wong 1979)...

Additional techniques, though by no means all of them, include machine learning AD, clustering algorithms, and hybrid approaches, which may combine anomaly- and signature-based detections. (Related reading:Splunk App for Anomaly Detection.)
Machine learning algorithms can analyze language patterns and respond to user queries in a natural and accurate way.Virtual assistants are applications of machine learning that interact with users through voice instructions. They are used to replace the work performed by human personal assistants, which...
