We have seen methods such as fit(), transform(), and fit_transform() in a lot of SciKit's libraries. And almost all tutorials, including the ones I've written, only tell you to just use one of these ...

In a very old post - Label Encoder vs. One Hot Encoder in Machine Learning - I had demonstrated how to use label encoding and one hot encoding to separate out categorical text data into numbers and d...
Read MoreIn most of our posts about machine learning, we've talked about overfitting and underfitting. But most of us don't yet know what those two terms mean. What does it acutally mean when a model is ov...
Read MoreNow that we know what is feature selection and how to do it, let's move our focus to validating the efficiency of our model. This is known as validation or cross validation, depending on what kind...

In our previous post, we discussed what is feature selection and why we need feature selection. In this post, we're going to look at the different methods used in feature selection. There are three ...

Today we'll be looking at a simple Linear Regression example in Python, and as always, we'll be using the SciKit Learn library. If you haven't yet looked into my posts about data pre-processing, which...

When you're working with a learning model, it is important to scale the features to a range which is centered around zero. This is done so that the variance of the features are in the same range. If a...

When you're working on a model and want to train it, you obviously have a dataset. But after training, we have to test the model on some test dataset. For this, you'll a dataset which is different fro...
Read More Most often than not, you'll encounter a dataset in your data science projects where you'll have missing data in at least one column. In some cases, you can just ignore that row by taking it out of th...
Read More Update: SciKit has a new library called the ColumnTransformer which has replaced LabelEncoding. You can check out this updated post about ColumnTransformer to know more. If you're new to Machine L...
