The scikit-learn Python machine learning library provides an implementation of the Lasso penalized regression algorithm via the Lasso class.Confusingly, the lambda term can be configured via the “alpha” argument when defining the class. The default value is 1.0 or a full penalty.1 2 3 ......
I also later found this post where Jason explains how one does naive baseline predictions using Zero Rule Algorithm: https://machinelearningmastery.com/implement-baseline-machine-learning-algorithms-scratch-python/ But I still don’t know how one can determine the upper bound for the expected perfo...
We do this until we reach the bottom, i.e, the algorithm converges and the loss has been minimised. Overfitting Overfitting:”Sherlock, your explanation of what just happened is too specific to the situation”.Regularisation:“Don’t overcomplicate things, Sherlock.” I’ll punch you for ...

The Ordinary Least Squares (OLS) regression technique is indeed a Supervised Learning algorithm used for estimating unknown parameters in a linear model. Its objective is to create a regression line that minimizes the sum of the squared errors between the observed data and the predicted values. By...
