What Does Backpropagation Mean?

feedbackPeople started working on artificial intelligence back in the late ’60s. After they came up with the concept of perceptron, this field looked very promising. But as the years passed by, no significant development took place even after making several attempts from multiple directions! As people were beginning to lose hope, backpropagation came into picture and breathed new life into this field. Backpropagation was the result of pioneering work by mathematicians and computer scientists, which eventually led to a successful revival of artificial intelligence! So what exactly is backpropagation? How is it used in real life?   Continue reading

Artificial Neural Networks

We want our machines to learn everything on their own as much as possible. Over the past few decades, researchers have come up with many theories and formulations about how we can achieve this in the best possible way. This realm is called machine learning. We come up with algorithms to teach the machines how to learn. I have discussed more about machine learning here. Human brain seems to achieve this rather effortlessly. Our ultimate goal is to make the machines as good as our brains, or even better. The formulation of Artificial Neural Network (ANN) is an attempt towards this.   Continue reading
