Meta-Learning to Cluster

Jiang, Yibo, Verma, Nakul

Understand

Clustering is one of the most fundamental and wide-spread techniques in exploratory data analysis.

  • Yet, the basic approach to clustering has not really changed: a practitioner hand-picks a task-specific clustering loss to optimize and fit the given data to reveal the underlying cluster structure.
  • Some types of losses---such as k-means, or its non-linear version: kernelized k-means (centroid based), and DBSCAN (density based)---are popular choices due to their good empirical performance on a range of applications.
  • Although every so often the clustering output using these standard losses fails to reveal the underlying structure, and the practitioner has to custom-design their own variation.
