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
Scikit-learnis one of the most popular machine learning libraries for Python, which provides a wide range of tools for data analysis and machine learning tasks, from simple linear regression to advanced clustering algorithms. This article will guide you through the steps to install and useScikit-l...
Scikit learn neural network is used to solve the many challenges we are facing in artificial intelligence. They are performing traditional ML models because it contains the advantages of variable interaction and non-linearity. Creating theneural networkwill begin from the perceptron; in simple terms, ...

AutoML also provides the capability to use multimodal data for modeling, integrating images and text with tabular data. Multimodal data modeling can help extract insights from diverse data sources. Traditional models often rely on a single type of data, limiting their capacity to fully capture the ...
In case you’ve missed my previous article about statsmodels, where I compare it with sklearn:Are you still using sklearn for Regression Analysis?Explanation of the summaryThe statsmodels index page shows a simple example of how to train an Ordinary Least Squares Regressions model:...
Now, some people may be wondering:"If I don't plan to perform original research, why would I need to learn the theory when I can just use existing ML packages?" This is a reasonable question! However,learning the fundamentals is important for anyone who plans to apply machine learning in...
The following code shows an example of training a regression model:Python Copy from sklearn.linear_model import LinearRegression model = LinearRegression() model.fit(X_train, y_train) After fitting the model, you can use the model to generate predictions on the test dataset to create model ...
To compute ALOOCV, we use the Python package bbai, which can be installed using pip: pip install bbai The Iris data already set comes packaged with sklearn. We can load and normalize the data set with this snippet of code: from sklearn.datasets import load_iris from sklearn.prepro...
