SELU (Scaled Exponential Linear Unit) Activation Function

We will look at the very promising but not very common activation function called SELU (Scaled Exponential Linear Unit) and understand its main advantages over other activation functions like ReLU (Rectified Linear Unit). This article presents lots of essential points about this function.

Machine learning, and for that matter artificial intelligence, uses a wide range of data to design models for a variation of tasks. This variation in the use of these models means the data types vary as well. In most scienti...

Error Detection in Computer Network

In this article, we are going to explore about error detection in computer networks. We will be seeing some standard error detecting codes which help in detecting errors. So let's get started.

Network Layer Protocols

The Open Systems Interconnection (OSI) reference model is one of the most crucial networking concepts to comprehend. This conceptual model illustrates a network architecture that enables data to be transferred between computer systems.

Each layer of the OSI model serves a distinct purpose. In this article, we will discuss about the functions of network layer and the protocols that are linked with it.

How to design a System? (Cheatsheet)

In this article, we have covered the process of developing a system's components, architecture, and interfaces to satisfy end-user needs which is referred to as system design. Reliability, Scalability, Availability, and Maintainability are all factors that must be considered while making decisions.

Implementing Random Feature at OpenGenus IQ

I was tasked by OpenGenus to implement a random feature, literally. It was going to be a page that immediately redirected a user to a random opengenus article. You can check it out here. So in this article, we will be going through the process of how I developed the random feature.

Feature: iq.opengenus.org/random/Code: github.com/OpenGenus/randomFeature Specification

I was tasked by the very gracious Aditya Chatterjee as part of my internship to implement the random feature for opengenus. I...

Master theorem for Time Complexity analysis
