How to Develop LARS Regression Models in Python?

What is LARS regression? Regression is the analysis of how a variable (the outcome variable) depends on the evolution of other variables (explanatory variables). In regression, we are looking for the answer to the question of what is the function that can be used to predict the value of another variable Y by knowing the … Read more

Logistic Regression in Python Scikit-Learn

Logistic regression is a popular algorithm for classification problems (despite its name indicating that it is a “regression” algorithm). It belongs to one of the most important algorithms in the machine learning space. Linear Regression Background Let’s review linear regression. Given the training data, we compute a line that fits this training data so that … Read more

Random Forest Classifier with sklearn

Does your model’s prediction accuracy suck but you need to meet the deadline at all costs? Try the quick and dirty “meta-learning” approach called ensemble learning. In this article, you’ll learn about a specific ensemble learning technique called random forests that combines the predictions (or classifications) of multiple machine learning algorithms. In many cases, it … Read more

SVM sklearn: Python Support Vector Machines Made Simple

Support Vector Machines (SVM) have gained huge popularity in recent years. The reason is their robust classification performance – even in high-dimensional spaces: SVMs even work if there are more dimensions (features) than data items. This is unusual for classification algorithms because of the curse of dimensionality – with increasing dimensionality, data becomes extremely sparse … Read more

K-Nearest Neighbors (KNN) with sklearn in Python

The popular K-Nearest Neighbors (KNN) algorithm is used for regression and classification in many applications such as recommender systems, image classification, and financial data forecasting. It is the basis of many advanced machine learning techniques (e.g., in information retrieval). There is no doubt that understanding KNN is an important building block of your proficient computer … Read more

Logistic Regression Scikit-learn vs Statsmodels

What’s the difference between Statsmodels and Scikit-learn? Both have ordinary least squares and logistic regression, so it seems like Python is giving us two ways to do the same thing. Statsmodels offers modeling from the perspective of statistics. Scikit-learn offers some of the same models from the perspective of machine learning. So we need to … Read more

To help you grasp this topic thoroughly, I attacked it from different perspectives: textual, visual, and audio-visual. So, let’s get started! Why Decision Trees? Deep learning has become the megatrend within artificial intelligence and … Read more

Why does Python Look Great on Your Resume?

Nothing to add—let’s get started! ? Python is the fastest-growing major programming language. A StackOverflow 2019 developer survey shows that Python is not only faster growing than C++, Java, JavaScript, and any other major programming language, it also comes with a happier community that loves the language most. Python is great for machine learning. Python comes with … Read more

Why Should I Use NumPy?

NumPy is not the trendiest Python library in the world. There are libraries such as TensorFlow or Scikit-learn for machine learning. These libraries get all the attention these days. However, in this article, I want to highlight the importance of learning the basics first. You cannot learn TensorFlow before you’ve learned Python. Similarly, you cannot … Read more
