Hello, I'm Yoshi24517. I noticed that in this edit to Sparse PCA, you removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you.  Yoshi24517 ( Chat ) ( Online ) 20:18, 1 December 2023 (UTC)

Please do not remove content or templates from pages on Wikipedia, as you did with this edit to Sparse PCA, without giving a valid reason for the removal in the edit summary. Your content removal does not appear constructive and has been reverted. Please make use of the sandbox if you would like to experiment with test edits. Thank you.

Please stop your disruptive editing. If you continue to blank out or remove content, templates, or other materials from Wikipedia, as you did with this edit to Sparse PCA, you may be blocked from editing. Lazylaces (Talk to me) 20:31, 1 December 2023 (UTC)
