Lasso Regression is an extension of linear regression that adds a regularization penalty to the loss function during training. How to evaluate a Lasso Regression model and use a final model to make predictions for new data. How to configure the Lasso Regression model for a new dataset via grid...
These problems are referred to as multiple-output regression, or multioutput regression. Regression: Predict a single numeric output given an input. Multioutput Regression: Predict two or more numeric outputs given an input. In multioutput regression, typically the outputs are dependent upon the inpu...
Logistic regression is an estimation of Logit function. Logit function is simply a log of odds in favor of the event. This function creates a s-shaped curve with the probability estimate, which is very similar to the required step wise function. Here goes the first definition : Logit Function...

In this step-by-step tutorial, you'll build a neural network from scratch as an introduction to the world of artificial intelligence (AI) in Python. You'll learn how to train your neural network and make accurate predictions based on a given dataset.
Linear regression is rooted strongly in the field of statistical learning and therefore the model must be checked for the ‘goodness of fit’. This article shows you the essential steps of this task in a Python ecosystem.
B1 is the coefficient (weight) linked to x. When you build a simple linear regression model, the goal is to find the parameters B0 and B1. To find the best parameters, we use gradient descent. Imagine your model finds that the best parameters are B0 = 10 and B1 = 12. ...
It looks like a good model, but sometimes the model fits the data points too much, mean the line passes through most for the data point in the above graph. Which resulting inoverfitting. To create the line (red) using the actual value, the regression model will iterate and recalculate the...
It’s based on Bayes’ theorem and makes predictions by calculating the probability of a data point belonging to a certain class. Now we will look into another type of Supervised Learning Model that is quite famous in the machine learning domain. Regression Regression in machine learning is a...
In our case, we’re creating a model from historical customer data to predict which customers are likely to leave. Since we need to classify customers as either churn or no-churn, we’ll train a simple-yet-powerful classification model. Our model uses logistic regression on a...
