WebFeb 10, 2024 · Nonetheless, finding anchor points remains a non-trivial task, and the estimation accuracy is also often throttled by the number of available anchor points. In this paper, we propose an alternative option to the above task. Our main contribution is the discovery of an efficient estimation procedure based on a clusterability condition.
WebAssess clustering tendency (clusterability) It is important to assess cluster tendency (i.e. to determine whether data contain meaningful clusters) before running any clustering algorithms. In unsupervised learning, the clustering methods returns clusters even if the data does not contain any meaninful cluster pattern.
