The most critical part of any Deep Learning model is finding the values of hyperparameters that would result in a model with high accuracy.

Learning Rate, Batch size, number of neurons in a layer are some common examples of model hyperparameters.


In continuation to Part-1, I bring up to you, more concepts of Deep Learning in a consolidated way. Please check the Introduction and “is this article for you?” in the first part.

Learning Rate and Scheduler

The optimization algorithm tells when to update the model parameters. The learning rate tells how much update should…


There are a lot of resources on Deep Learning available online as well as on books. But it’s hard to find a consolidated version, so I decided to come up with some articles that would present topics in a summarized way.

For whom is this article? The article would really…


In a practical deep learning approach, you write code for everything. You preprocess your data using code, create and train the model using code, create output visualizations through code, everything through code. What if I say you could minimize your coding efforts using a tool that requires only drag and…


In this article, I will show you how to determine facial landmarks using the dlib library, how to calculate EAR(Eye Aspect Ratio), and use the concept of EAR to detect drowsiness.

Before you begin with the code part of this article, you would have to install dlib library in python…


To all the people who are wondering how can this concept be covered inside an article, I would say things sound complicated until you have explored the depths of it. I will not say that the article would be very easy but yes it would be built on top of…


Answers to most computer vision problems lie in finding and analyzing the shapes present in the image, and getting the contour is one such approach for it. …


Some of the popular techniques for counting fingers in a image are by training a CNN or using contours and convexity hull. …


If I say you wanted to do something with hand gesture recognition in python, what would be the first solution that will pop in your mind: train a CNN, contours, or convexity hull. …


A long time back one of my friends asked me to check this cool idea which was simply a small display device that “keeps you updated for anything important for you”. Somehow the idea did not succeed in raising funds and eventually scraped out.

Just for reference purposes. No intention to create the exact device. This image is completely part of https://smart-stickers.com/. The red part is what we are trying to achieve through this article

The idea

Though it was not possible for…
