Off the top of my head,
- Principal component analysis
- Fitting a plane to a set of points
- Linear least squares
- chestervonwinch 6y agoAll of these examples are equivalent to least squares :)
- solinent 6y agoYeah, for the most part all of engineering is equivalent to least squares I'd say, there's always some non-linear optimization procedure that uses a norm^2 metric since it's so well studied and solved already. It's disappointing as a mathematician, but the rest of me is fine with it :)
- vecter 6y agoHow is PCA the same as least squares? I've always understood it as the eigendecomposition of the covariance matrix.
- dumb1224 6y agoI work with scientific data but have to say I have a very shallow math background and also forgotten most what I learnt at school/uni. However whenever I click open the source for scikit-learn / high level code published in papers I see SVD. A lot of the scenarios in biology have been abstracted to be matrix manipulation which is fascinating and I really need to learn.
