The train-test split technique is a way of evaluating the performance of machine learning models. Whenever you build machine learning models, you will be training the model on a specific dataset (X and y). Once trained, you want to ensure the trained model is capable of performing well on the unseen test data as well. …
“How is machinelearningplus university different from other courses?”. Other courses include those you see on Coursera, Udemy, Udacity, Youtube and courses offered by universities. I think this is important to know, so let me try and answer this question. First of all, let me clarify that some of these courses are taught by great accomplished …

Why learn the math behind machine learning algorithms when you can readily implement it using the python libraries like scikit-learn, h2o, statsmodels etc? This is a fair question especially coming from beginners when it is easy to implement ML with few lines of code and get the results fast. Now, you must understand that learning …

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 …
The size of the data you can load and train in your local computer is typically limited by the memory in your computer. Let’s explore various options of how to deal with big data in python for your ML projects. In certain situations, you might have a hard time working on large data, that is …

Granger Causality test is a statistical test that is used to determine if a given time series and it’s lags is helpful in explaining the value of another series. You can implement this in Python using the statsmodels package. That is, the Granger Causality can be used to check if a given series is a …
Introduced in 1969 by Clive Granger, Granger causality test is a statistical test that is used to determine if a particular time series is helpful in forecasting another series. What is Granger Causality? Let’s first understand when is the Granger causality test is useful. Let’s say you have two time series data X and Y, …
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 …
Population stability Index (PSI) is a model monitoring metric that is used to quantify how much the distribution of a continuous response variable has changed between two given samples, typically collected at different points in time. Originally, PSI was used to check if the distribution of the Y (aka the response variable or the scoring …
Now let’s understand list comprehensions this is a slightly more advanced concept compared to list a list comprehension. Now, remember earlier, I was giving you one to one problem and in order to solve that problem you need to understand list and list comprehension. We have now understood what list is let’s get to a …
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, …
