Today, I want to discuss some of the common mistakes that programmers make when starting to learn machine learning. But first, let me speak about why software engineers should start looking into ML. First, let’s see why programmers should start ML? Today, from what I’ve seen, people coming with a strong software engineering background, good …

The use cases of machine learning to real world problems keeps growing as ML/AI sees increased adoption across industries. However, there are certain core use cases that add lot of value for organizations and you’ll often find them being implemented in banks, healthcare, manufacturing, product companies or by consulting organizations as well. Let’s tour of …
Not all Data Science projects that get kicked-off see the light of day. While this is true for any project, there are common reasons specific to Data Science projects, which can be avoided. These can either be prevented if you are aware and not commit these mistakes. Or if you see these problems, consider avoiding …
Let’s understand the formula for the linear regression coefficients. That is the formula for both alpha and the beta. Now, if you have simple linear regression that does, you have just 1x variable in your data, you will be able to compute the values of alpha and beta using this formula. Let’s suppose you …
In this lesson, I introduce what Linear regression is all about. Linear Regression is a foundational algorithm for machine learning and statistical modeling. Traditionally, Linear Regression is the very first algorithm you’d learn when getting started with predictive modeling. While there are a lot more ML and Deep learning algorithm in use today, …

Nebullvm is an open-source library that takes a deep learning model as input and outputs an optimized version that runs 5-20 times faster on your machine. Nebullvm tests multiple deep learning compilers to identify the best possible way to execute your model on your specific hardware, without impacting the accuracy of your model (GitHub link). …
Gradient Boosting is a machine learning algorithm, used for both classification and regression problems. It works on the principle that many weak learners(eg: shallow trees) can together make a more accurate predictor. How does Gradient Boosting Work? Gradient boosting works by building simpler (weak) prediction models sequentially where each model tries to predict the error …

Bias Variance Tradeoff is a design consideration when training the machine learning model. Certain algorithms inherently have a high bias and low variance and vice-versa. In this one, the concept of bias-variance tradeoff is clearly explained so you make an informed decision when training your ML models Bias Variance Tradeoff – Clearly Explained. Photo by …

Compare the popular deep learning frameworks: Tensorflow vs Pytorch. We will go into the details behind how TensorFlow 1.x, TensorFlow 2.0 and PyTorch compare against eachother. And how does keras fit in here. Table of Contents: Introduction Tensorflow: 1.x vs 2 Difference between static and dynamic computation graph Keras integration or rather centralization What is …
Principal Components Analysis (PCA) is an algorithm to transform the columns of a dataset into a new set of features called Principal Components. By doing this, a large chunk of the information across the full dataset is effectively compressed in fewer feature columns. This enables dimensionality reduction and ability to visualize the separation of classes …
In machine learning, Feature selection is the process of choosing variables that are useful in predicting the response (Y). It is considered a good practice to identify which features are important when building predictive models. In this post, you will see how to implement 10 powerful feature selection approaches in R. Introduction 1. Boruta 2. …

Choosing the right evaluation metric for classification models is important to the success of a machine learning app. Monitoring only the ‘accuracy score’ gives an incomplete picture of your model’s performance and can impact the effectiveness. So, consider the following 15 evaluation metrics before you finalize on the KPIs of your classifier model. Introduction: Building …
Logistic regression is a predictive modelling algorithm that is used when the Y variable is binary categorical. That is, it can take only two values like 1 or 0. The goal is to determine a mathematical equation that can be used to predict the probability of event 1. Once the equation is established, it can …

We have covered the basic concepts about linear regression. Besides these, you need to understand that linear regression is based on certain underlying assumptions that must be taken care especially when working with multiple Xs. Once you are familiar with that, the advanced regression models will show you around the various special cases where a …
