Overfitting and Underfitting models in Machine Learning

cdc-height-age-chart

In 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 overfit, or underfit? Why are they considered not good? Read more...

Different types of Validations in Machine Learning (Cross Validation)

Now 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 of validation method you’re using. Read more...

Different methods of feature selection

Feature_selection_Embedded_Method

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 main classification of feature selection methods – Filter Methods, Wrapper Methods, and Embedded Methods. Read more...

Why do we need feature scaling in Machine Learning and how to do it using SciKit Learn?

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 feature’s variance is orders of magnitude more than the variance of other features, that particular feature might dominate other features in the dataset, which is not something we want happening in our model.

Use Config Caching to Speed Up Your Laravel App

As web developers, we’re always looking for ways to speed up our app. It’s all about milliseconds today. There are several ways by which a web app or a web service could be optimised for speed. Being one of the most used and popular PHP frameworks, Laravel has a few tricks up its sleeves to make this happen. Read more...

Why I love curly brackets

Curly brackets. Well, what can I say about them? They sure do have curves! And such curves, I’m addicted! I’ve been abusing them for as long as I remember. I abuse them even today. The day I saw a piece of code for the first time, over a decade ago, I knew I’d be using those curly brackets for the rest of my life.
