Learn about the most popular sorting algorithms and save them for revisiting before your next interview. I’m sure you’ve seen or written at least one sorting algorithm in your life. However, we often overlook how they differ from one another, particularly in terms of time and space complexities. This article…

Learn how to implement logistic regression with gradient descent optimization from scratch. Introduction In this hands-on tutorial, we will see how we can implement logistic regression with a gradient descent optimization algorithm. We will also apply regularization technique for the generalization of the model. We will implement everything by using only…

Introduction The current generation, namely the 2nd generation of artificial neural networks, has made a tremendous breakthrough in numerous fields. …

Learn how to use nuScenes dataset for autonomous driving Introduction The nuScenes dataset is a large public dataset for autonomous driving developed by Motional. It consists of 1000 driving scenes from Boston and Singapore, chosen to show a diverse range of driving situations, traffic, and unexpected behaviors. The scenes are annotated…

In computer graphics, it is easy to detect a 2D object using a mouse event in OpenGL because the view-port or screen is 2D. However, detecting a 3D object using a mouse click becomes more complicated when the 3D space model has perspective projection. To illustrate, consider the following example: …
