Alternative regression model algorithms for machine learning I am looking for not so known regression models and if possible a python library that implements it.
In my quiver I have:

Generalized Linear Models, Linear, Lasso, Ridge...
Decision Tree based model: CART, Random Forest, Gradient Boosting Decision trees(xgb,lightgbm,catboost)
Support Vector Machines
Knn Regressor
Neural Networks

Are there regression algorithm less known? I am looking for alternatives models to add to my quiver.
Multiple regression
multivariate regression
Mixed Models
elastic search
Partial Least Squares regression
Logistic regression
Bayesian regression and many more..
