replace something like {\displaystyle\min_{\beta\in\mathbb{R}^{p}}\left\{\left\|y-\sum_{j=1}^{J}X_{j}\beta_{j}\right\|_{2}^{2}+\lambda\sum_{j=1}^{J}\|\beta_{j}\|_{K_{j}}\right\},\qquad\|z\|_{K_{j}}=(z^{t}K_{j}z)^{1/2}} with https://i.imgur.com/qJhJote.png

It's easy to do: Just add <script type="text/javascript" async src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-MML-AM_CHTML" async></script> to the html template. That will let you use \( to enter inline latex mode and \) to exit inline latex mode or $$ and $$ to enter and exit equation mode (centered equation as its own line)

It's the objective function for the group lasso in the Lagrangian form. Lasso = least absolute shrinkage and selection operator and the group lasso is an extension that allows predefined groups of covariates to collectively be included in or excluded from a model. See http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.79.2062&rep=rep1&type=pdf

Huh. Yeah I see the Lagrangian set up. My econometrics is pretty strong but I haven’t come across this LASSO technique — I either missed it, or it hasn’t come across to econometrics. Data mining technique?

Yeah. It's a technique for selecting features and regularizing regression models. The standard lasso selects a subset of the given covariates for use in the model, thereby limiting overfitting. The group lasso extends this idea by allowing groups of predefined covariates to be selected into or out of the model together. It's good in settings where categorical variables are encoded as a hierarchical collection of binary covariates, which is typically an instance in which random forests, for example, will underperform due to computational complexity & bias toward features with more levels. However, the lasso is by nature tailored to linear models, which isn't a constraint for random forests as decision trees are nonlinear.

OK I think I follow. Yeah not too familiar with this area, have never done much big data, and data mining is generally frowned on in more orthodox econometrics as letting the data determine the model, rather than letting the theory determine the model and then testing the model against the data. But I know a lot of people are getting into big data techniques and it’s something I should get up to speed on before too long.

Model selection always occurs after feature extraction. Basically, you look at the data and try to figure out the important variables via domain experts, dimensionality reduction techniques, heuristics, etc. Then, once you have an idea of how the independent variables affect the dependent variables, you choose a modeling approach that makes sense given the context. The hardest part is fitting (but not overfitting) the model to the data while preserving prediction accuracy.

The trick is to lessen the extent to which the data reflects reality via regularization or other techniques that limit overfitting

What are you trying to do? machine learning and, more broadly, artificial intelligence provide solutions to many different types of problems. Regression is just a technique for assigning a continuous value to the output variable. Classification assigns a class label to the output variable. Most regression analysis relies on linear models. If you're looking to get away from logistic or linear regression and have nonlinear data, look into random forests. They're based on decision trees (which are nonlinear models) and they're extremely good at both classification and regression, especially when combined with pruning and bagging & boosting techniques.
