Ridge regression
The $$J(\theta) = \frac{1}{2n} \sum_{i=1}^{n}(h_{\theta}(x^i) - y^i)^2 + \frac{\lambda}{2} \sum_{j=1}^{d} \theta_j^2 $$ expression looks like ridge regression and the article sounds like regularization, which started much earlier than 1974. Is this another example of machine learning reinventing statistics? 2A00:23C6:148A:9B01:FD80:6DD5:B1DD:C160 (talk) 02:05, 3 October 2023 (UTC)
