Register Seriation Based on OPTICS

Description

Use ordering points to identify the clustering structure (OPTICS) to create a seriation order.

Usage

register_optics()

Details

Registers the method "optics" for seriate. This method applies the OPTICS ordering algorithm to create an ordering.

Note: Package dbscan needs to be installed.
