Another mathematics "topic" that is just two common words used together in different contexts. User:力 (powera, π, ν) 04:33, 1 December 2021 (UTC)[reply]

• Delete. Unlike spatial complexity, I think there is a real idea here, but a small, old, and obvious one: sometimes in optimization problems, applying a nonlinear function can transform the problem into something more obviously solvable. A standard example is that certain quadratic optimization problems can be transformed into linear ones by mapping vectors into higher-dimensional spaces using the squared norm or other quadratic combinations of coordinates as the extra dimensions. However, this would need to be an entirely different article, not focusing on Polyak's old wine in new bottles, so WP:TNT still applies. —David Eppstein (talk) 08:43, 1 December 2021 (UTC)[reply]
• Keep, this is a specific idea and passes WP:GNG based on the sources in the article. SailingInABathTub (talk) 12:28, 3 December 2021 (UTC)[reply]
• Delete per WP:TNT. The term definitely predates Polyak, e.g., The effects of higher order correlations sometimes can be removed by nonlinear rescaling of the axes, using Detrended Correspondence Analysis (DCA) or related multivariate methods (Melhlop and Lynch 1986). So, of the three sentences in the stub, one of them is factually wrong. Of the four sources, two are being used misleadingly and one, being an arXiv preprint, is not reliable.
