   An introduction to Convolutional Neural Networks   Introduction: What is an artificial neural network? In recent times, words like deep learning, machine learning and artificial intelligence have become so common that even school kids are now somewhat familiar with these terms. The advent of Machine Learning has been followed by the rise of Artificial Neural Networks (ANNs). ANNs are computational processing systems used to handle a large amount of data. They take inspiration from the way biological nervous systems operate. These neural networks have a number of hidden layers stacked upon each other. The basic computational units of a neural network are called neurons. Just like neurons in the human brain, these fundamental blocks take in input signals, process them and produce the output. Figure 1 below shows the basic structure of any ANN architecture: Figure 1 What are convolutional neural networks? In this article, we will focus on Convolutional Neural Networks (CN...

   Journey   to   the   Stars:   The   Inspiring   Story   of   Captain   Prasanth   Balakrishnan   Nair   Gaganyaan   Astronaut     The Gaganyaan, literally meaning 'celestial vehicle', will carry the astronauts to an orbit of 400 km on a three-day mission and return them   safely to Earth by landing in Indian sea waters. "After 40 years, an Indian will go to space, but this time, the time is also   ours, the countdown is also ours.   One   of   the   four   astronaut   designated   who   will   fly   to   low-Earth   orbit   as   part   of   ISRO’s   Gaganyaan is the son of a retired engineer and comes from a village in Kerala’s   Palakkad.   Nemmara village erupted in joy as PM Narendra Modi announced the   name of Prasanth Balakrishnan Nair, who will be the group captain of the   f...

  Why is History Important? History is Boring they say History, an area of study which is more often than not considered to be the realm of dusty books, difficult to remember significant dates and, just to put it in short, plain boredom. Such is the opinion that has been predominantly held by everyone I interacted with in my life. What is there in it but some old artifacts and some kings who lived long ago who may have done something great in their lifetimes? Why do we even need to take interest in a subject with minimal relevance to us? Let us see why. What is History? In the simplest terms, it is record keeping. We in our daily life try to keep a record of significant moments for remembrance by taking photos, companies and institutions keep records to track their progress, project records are kept for analysis in order to refine utilized processes, financial records to keep track of monetary resources, etc. History is such a record on a grander scale, kept to analyz...
