Talk:Decision tree pruning

The images
The images used in this article are pathetic, not to mention the article itself. --130.126.161.120 15:20, 26 October 2007 (UTC)

Needs cleanup
At the very least, the images need to be replaced. Some expansion wouldn't hurt, either. Reference to and comparison with branch and bound, perhaps?

There's also an (unrelated) algorithm called "pruning algorithm" by J. Felsenstein, described in, but there seems to be no article about it.... &mdash;MoA)gnome (talk) 15:18, 4 May 2008 (UTC)

broader meaning
In my understanding, pruning in algorithm has a much broader meaning than pruning a decision tree, e.g., pruning in branch and bound. Anyone agree? Took (talk) 21:47, 25 August 2009 (UTC)

"Decision Stream" Editing Campaign
This article has been targeted by an (apparent) campaign to insert "Decision Stream" into various Wikipedia pages about machine learning. "Decision Stream" refers to a recently published paper that currently has zero academic citations. The number of articles that have been specifically edited to include "Decision Stream" within the last couple of months suggests conflict-of-interest editing by someone who wants to advertise this paper. They are monitoring these pages and quickly reverting any edits to remove this content.

Known articles targeted:
 * Artificial intelligence
 * Statistical classification
 * Deep learning
 * Random forest
 * Decision tree learning
 * Decision tree
 * Pruning (decision trees)
 * Predictive analytics
 * Chi-square automatic interaction detection
 * MNIST database  — Preceding unsigned comment added by ForgotMyPW (talk • contribs) 17:40, 2 September 2018 (UTC)

Dear BustYourMyth,

Your activity is quite suspiciase: registration of the user just to delete the mention of the one popular article. Peaple from different contries with the positive hystory of Wikipedia improvement are taking place in removing of your commits as well as in providing information about "Decision Stream".

Kind regards, Dave — Preceding unsigned comment added by 62.119.167.36 (talk) 13:32, 27 July 2018 (UTC)

What's the role of pruning in a compression scheme?
A compression scheme in a learning algorithm aims to compress learned knowledge without affecting the model's performance. Which role does pruning play in a compression scheme? How does pruning affect the weights in the model? After pruning, should the compression scheme be tested on smaller prototypes? Inlin (talk) 15:14, 11 August 2023 (UTC)
