Is this a chandelier?  Is it a multi-tiered capsule? It’s a computer – a Quantum Computer. Quantum Computing is based on the concepts of Quantum Physics. These concepts are applied to perform calculations on the data and store it in Quantum Computer. So, what exactly is this Quantum Computer and how is it different from […]

Slow and Steady DOES NOT Win The Race

The world of today does not belong to the proverbial Tortoise that slowly crawls to the finish line; rather it belongs to the Rabbit that can hop, skip and jump in tandem with the needs of the customers. It is no longer the bigger taking over the smaller; but it is the faster over taking […]


90% of Indian engineering aspirants want to work at Google, work in Artificial Intelligence, Machine Learning, Big Data, Analytics. It is easy to see the end goal as the CEO of leading IT companies.  But it is the path that leads to that goal that is blurry andfuzzy.  After four years of undergraduate degree in […]

If Christopher Columbus Had Google Maps!

Marco Polo, Ibn Battuta, Vasco de Gama, Amerigo Vespusi, Christopher Columbus all explored the world to know more and find better travel routes.  But they largely relied on astronomical positions in the sky to steer their vessels.  We may have come a long way technologically; but we still rely on the skies – on our [...]

Neural Networks (NN) Basics And Neuron Activation Functions

Neural networks are adaptive learning systems, inspired by the biological neural systems. These may be trained with input-output data or may operate in a self-organizing mode. The basic block in an NN is the mathematical model of a neuron as in Eqn. 1. Three fundamental components of a neuron are the connection links that provide […]

Experience Teaches Everything

“We are the sum total of our experience. Those experiences, be they positive or negative make us the person we are, at any given point in our lives.” – B. J. Neblett. Knowledge comes from learning; but ‘experience’ comes from living. A life without problems and challenges is like a school without lessons. Teaching was […]
