To understand their different contexts we can look where their relationship to the computing industry comes from.

Implementing the k-means jump method: Part Four

This fourth and final part of our exploration into the jump method wraps things up by following a basic application of the technique through to a search for results we can be confident in.

We'll reuse functions from rest of the series (Part One, Part Two, Part Three). You'll also want the original paper handy to refer back to their charts.

First, we're going to return to several prior data sets:

$ planck
Planck 1.11
ClojureScript 1.8.44
    Docs: (doc function-name-here)
          (find-doc "part-of-name-here")
  Source: (source function-name-here)
    Exit: Control+D or :cljs/quit or exit or quit
 Results: Stored in vars *1, *2, *3, an exception in *e

Quick List of Resources for Topological Data Analysis with Emphasis on Machine Learning

This is just a quick list of resourses on TDA that I put together for @rickasaurus after he was asking for links to papers, books, etc on Twitter and is by no means an exhaustive list.

Survey Papers

Both Carlsson's and Ghrist's survey papers offer a very good introduction to the subject

Topology and Data by Gunnar Carlsson
Barcodes: The Persistent Topology of Data by Robert Ghrist

Other Papers and Web Resources

	;; ## Introduction

	;; This Gist demonstrates a generic way to migrate an entire Datomic database
	;; from an existing 'Origin Connection' to a clean 'Destination Connection',
	;; while getting rid of some undesirable data and otherwise preserving history.
