Clustering in data mining is used to group a set of objects into clusters based on the similarity between them. With this blog learn about its methods and applications.
In the development of a task-oriented dialogue system, defining the dialogue structure is a time-consuming task. Hence, several works have looked into automatically inferring it from data, e.g., actual conversations between a customer and a support agent. To recover such dialogue structure, recen...
Clustering is an unsupervised analysis technique, which plays a crucial role in exploring the internal structure information of data. Over time, various forms of single clustering methods have been developed. However, the limited scope of application prevents their simultaneous application to datasets wit...
Spatial clustering, which shares an analogy with single-cell clustering, has expanded the scope of tissue physiology studies from cell-centroid to structure-centroid with spatially resolved transcriptomics (SRT) data. Computational methods have undergone remarkable development in recent years, but a compre...
In search of deterministic methods for initializing K-means and Gaussian mixture clustering. The performance of K-means and Gaussian mixture model (GMM) clustering depends on the initial guess of partitions. Typically, clustering algorithms are ini...
