WebWe propose in this paper a hierarchical atlas-based fiber clustering method which utilizes multi-scale fiber neuroanatomical features to guide the clustering. In particular, for each level of the hierarchical clustering, specific scaled ROIs at the atlas are first diffused along the fiber directions, with the spatial confidence of diffused ROIs gradually decreasing … WebHierarchical cluster analysis in clinical research with heterogeneous ...

Enlightened by the field in physical space, data field to simulate nuclear field is presented to illuminate the interaction between objects in data space. In the data field, the self-organized … WebThe working of the AHC algorithm can be explained using the below steps: Step-1: Create each data point as a single cluster. Let's say there are N data points, so the number of clusters will also be N. Step-2: Take two closest data points or clusters and merge them to form one cluster. So, there will now be N-1 clusters.
