Overview section

I really like the first three paragraphs of the overview section. I'd like to remove the rest though, because it is only partially related. Less is more. Or we need more high-quality paragraphs here. I'll let this comment sink in for a while, I've done enough edits today (and tried to justify each one), let's see how many will be undone. Hobbes (talk) 20:38, 7 May 2009 (UTC)[reply]

Recognition vs. Analysis

Is there a difference between pattern analysis and pattern recognition?--Adoniscik (talk) 21:20, 28 December 2007 (UTC)[reply]

Unsupervised learning

Should this include unsupervised methods, too? E.g., clustering has major applications for pattern recognition. -- 16:55, 25 Mar 2005 (MET)

I disagree --- that material is already covered in unsupervised learning. Both supervised and unsupervised learning are covered in a high-level way at machine learning. -- hike395 17:37, 25 Mar 2005 (UTC)

Link to peer reviewed paper

Hi, I recently added some new information regarding the coparison of various classification techniques with a reference to a peer reviewed article (van der Walt and Barnard). There seems to be some controversy on this subject, the link has been removed several times. I am currently doing my PhD on this topic an I know the information is very relevant.

Is the reference and the external link http://www.patternrecognition.co.za suitable for this site? If not, what can I do so that this information is not repeatedly removed? -cvdwalt

As a scholar, you should know that you may give references to strengthen your claims that are detailed in your article, and not add unexpected references without any prior presentation. Your self-promotion is then, in my opinion, irrelevant both in this article and in Wikipedia. --131.254.15.97 (talk) 14:33, 24 March 2009 (UTC)[reply]

I agree with the previous comment. Furthermore, the research mentioned is very very specific and should maybe be moved to another page that could be linked from here. I also recall several other researchers that have dealt with this topic (e.g. T.K. Ho in her ICPR2004 paper, but there are others), which IMHO also speaks for a separate page.

Merging/reorganizing Pattern recognition and statistical classification

Merge with statistical classification somehow? -- hike395 08:25, 10 Mar 2005 (UTC)

Done. Made this the main article. -- hike395 15:42, 10 Mar 2005 (UTC)

Why has statistical classification been redirected to pattern recognition of all places? Statistical classification far pre-dates pattern recognition or machine learning and has uses far beyond either. I think it is more properly a category within statistics and/or cladistics/taxonomy than pattern recognition. A link to it is warranted from this page, but why the redirect? -- User:Jrbouldin

Take a look at [1], which was the old statistical classification article before the merge. It was entirely about statistical classification algorithms, which is the subject of this article and has more detail here. If you think there is more material in statistical classification beyond the material here (or in supervised learning), feel free to write something up. We can also refactor it into the right spot. If you want to write a draft (and not make an "official" article), you can write something at statistical classification/temp, and we can discuss what to do with it. It's up to you. --- hike395 June 29, 2005 22:32 (UTC)

Thank you for the clarification and other advice. I am new but will give it a shot. Seems to me the topic needs to made more general.Jeeb 1 July 2005 01:39 (UTC)

Please see Talk:statistical classification for a continuation of this discussion. Thanks! hike395

Human pattern recognition?

Numerology (for example) links here and yet this article is entirely about pattern recognition as performed by machines. Surely humans recognize patterns too. Recury 21:00, 3 July 2006 (UTC)[reply]

Yes, how about some information on patern recognition in humans? 66.24.195.123 12:39, 19 August 2006 (UTC)[reply]

To point you in the direction, an example is how we hear words in music played backwards —Preceding unsigned comment added by 24.5.91.222 (talk) 01:33, 14 December 2009 (UTC)[reply]

Hidden Messages sidebar

"Hidden messages" sidebar is out of main topic of "Pattern recognition". I see no need to have in such a dominant place links to themes like Reverse speech or Numerology. I suggest removing sidebar "Hidden messages". Msm 10:51, 13 March 2007 (UTC)[reply]

No one was against my suggestion in a week time, so I remove hidden messages because of reasons written above. Msm 22:47, 20 March 2007 (UTC)[reply]

I also object to it so I posted a message on its talk page since it's back again. Let's form a consensus so we don't add/delete it repeatedly.--Adoniscik (talk) 06:35, 2 January 2008 (UTC)[reply]

Rule of three

Someone links to Rule of three (writing) in the See Also section. I see no relevance so I'll remove it. Could someone give justification here before putting it back in. --Offput 15:40, 23 March 2007 (UTC)[reply]

Contradiction

Huge contradiction in the introduction of the article: techniques of a sub-domain of automatic learning cannot rely on a priori knowledge! Do you know what you speak of or just quote on scholars? —Preceding unsigned comment added by 137.108.145.250 (talk) 10:15, 19 September 2007 (UTC)[reply]

major rewrite

I just rewrote the article almost totally (except for a couple of sections at the end), to reflect what I believe "pattern recognition" to actually be. The former article basically just described the process of classification, with a bit of other stuff thrown in. As used in books such as Christopher Bishop "Pattern Recognition and Machine Learning" (more or less the "bible" nowadays), pattern recognition clearly refers to any sort of automatic labeling of input data: Not just classifying data into one of a fixed set of classes, but clustering the data (including learning the number of clusters from the data), regression (producing a real-valued label), sequence labeling such as using an HMM or Kalman filter, etc. Bishop does not explicitly discuss syntactic parsing, but this would clearly also qualify as a type of pattern recognition.

Category:Pattern recognition

I think it should be created the category "Category:Pattern recognition" to put there all types of pattern recognition, like in the Spanish edition of Wikipedia ("es:Categoría:Reconocimiento de patrones"). What do you think?--Aliuken (talk) 19:51, 31 May 2011 (UTC)[reply]
