The McCulloch-Pitts model was an extremely simple artificial neuron. The inputs could be either a zero or a one. And the output was a zero or a one. And each input could be either excitatory or inhibitory. Now the whole point was to sum the inputs. If an input is one, and is excitatory in [...]

All about biological neurons
Artificial neural networks are inspired from biological ones. So it makes sense to know a bit about biological neural networks as well. You brain is a neural network. One really really complex neural network. It has 1011 neurons. And each of these neurons is connected to approximately 104 other neurons. These interconnected neurons use electrical [...]
What exactly is a Neural Network?
Today, computers are greatly evolved machines. They run at blindingly fast processor speeds of around 3 GHz. That too with multiple cores. They can do calculations, perform mathematical manipulations, forecast weather, guide missles with pin point accuracy. Something which humans simply cannot do at such high speeds. But there are tasks that humans can do [...]
