Talk:Weak supervision

This entire article is wrong

It conflates semi-supervised learning and weak supervision. The two are related but distinct areas of machine learning. Semi-supervised learning DOES NOT use noisy, limited, or imprecise sources. Instead, it propagates information from (small amounts) of labeled data to unlabeled data. Weak supervision on the other hand does use noisy, limited, or imprecise sources about an unobserved target variable. 72.182.48.217 (talk) 16:07, 22 February 2023 (UTC)

I created a new page for weak supervision and separated the two topics. The new page for weak supervision comments on the difference to semi-supervised learning. Psnby (talk) 17:20, 22 February 2023 (UTC)

My edit was undone, so now this page is wrong again. I have a PhD in machine learning and I can assure everyone that weak supervision and semi-supervised learning should not be conflated in the same article. Psnby (talk) 18:16, 22 February 2023 (UTC)

@Psnby: You have argued that semi-supervised learning and weak supervision are separate concepts, even though this article discusses them as if they are the same thing. Please provide a reliable source that differentiates the two. (Your PhD, while impressive, is not a reliable source. You'll need to point to actual published sources.)

An example would be the article below (cited 24 times at this time), which while a preprint, includes Alex Ratner as an author. Alex Rather is an author whose research articles are cited as primary sources on weak supervision in this wiki entry. The paper below clearly distinguishes semi-supervised learning as a different, complementary approach to weak supervision in Section 7.

@Psnby: Very well. Thank you for clarifying. WikiDan61^ChatMe!_ReadMe!! 22:19, 22 February 2023 (UTC)

I submitted a draft for an article on Weak Supervision which just separates out the weak supervision component of the Semi-supervised learning entry and makes tiny edits such as a clarification regarding the difference to Semi-supervised learning. If there is anything I can do to make things clearer or help the process along I'd appreciate some help as I am still very unfamiliar with editing etc on this platform.

@Psnby: The warning you placed is less than helpful. If you are able to improve the article, do so. (Reference this discussion if you make large changes that might be questioned again.) WikiDan61^ChatMe!_ReadMe!! 12:32, 23 February 2023 (UTC)

Here is another well-cited survey paper which distinguishes weak supervision from semi-supervision:

Zhou, Zhi-Hua. "A brief introduction to weakly supervised learning." National science review 5.1 (2018): 44-53.

So I think this present article is confusing on two fronts: first semi-supervision is rarely called weak supervision. For instance, both survey articles referenced in this article call the subject of this article "semi-supervision". Almost all of the references in the article refer to this problem as semi-supervision and I cannot see a single instance where it is called weak supervision.

Second, weak supervision usually denotes a problem distinct from the semi-supervision. In addition to the two, papers already mentioned in this thread I'd add the ECCV tutorial: https://hbilen.github.io/wsl-eccv20.github.io/ . I'd also add these survey papers:

Zhang, Man, et al. "A survey of semi-and weakly supervised semantic segmentation of images." Artificial Intelligence Review 53 (2020): 4259-4288.

Zhang, Dingwen, et al. "Weakly supervised object localization and detection: A survey." IEEE transactions on pattern analysis and machine intelligence 44.9 (2021): 5866-5885.

Qu, Linhao, et al. "Towards label-efficient automatic diagnosis and analysis: a comprehensive survey of advanced deep learning-based weakly-supervised, semi-supervised and self-supervised techniques in histopathological image analysis." Physics in Medicine & Biology (2022).

I'm not sure how to demerge these pages by the wiki process. Genusfour (talk) 07:54, 3 June 2023 (UTC)

I think It would be useful to open a new thread/issue. Clearly, the issue has not been addressed. 136.49.39.161 (talk) 19:14, 12 June 2023 (UTC)

I'm happy to second @Psnby's opinion. The existing article is very misleading, and most of it is describing semi-supervised learning but not weak supervision. I think the easiest fix is to change the title perhaps WuTheFWasThat (talk) 18:51, 30 November 2023 (UTC)

Requested move 22 March 2023

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review after discussing it on the closer's talk page. No further edits should be made to this discussion.

The result of the move request was: moved to Weak supervision. While most of the discussion pertained to the fact that "Semi-Supervised Learning" is an inappropriate title under WP:NCCAPS, it was also noted that this page had recently been WP:BOLDly merged away from its previous title of "Weak supervision". One participant suggested a reversion to that previous title, and other participants appeared amenable to that suggestion, leading to a consensus for "Weak supervision".

Semi-Supervised Learning → ? Semi-supervised learning – Per WP:NCCAPS. This is not a proper name. Also most search results for "Semi-Supervised Learning" on Google Scholar are lowercase. HTinC23 (talk) 21:53, 22 March 2023 (UTC)

• Oppose after checking the page's history, it seems it was involved in some bold merges that were against policy. Ultimately, Semi-supervised learning needs to be recreated instead of moving this page to its place. This page should be moved back to Weak supervision where it formerly was and made a redirect. ᴢxᴄᴠʙɴᴍ (ᴛ) 01:10, 23 March 2023 (UTC)

  I am also happy if this goes back to Weak supervision. I don't know enough to comment on the merge. I changed the template to {{requested move/dated|?}}.—HTinC23 (talk) 02:01, 23 March 2023 (UTC)

  That change to the RM template caused an error. Tried to fix it; if the RM bot still finds one, I can retry a fix. Rotideypoc41352 (talk · contribs) 14:15, 23 March 2023 (UTC)
