For people who are interested in biometrics, expert systems and robotics cam take up this interesting course on Machine learning. It is basically a science related to construction and study of algorithms. The tutorials will help you understand the basics of machine learning, Perceptron Learning, Backpropagation learning and all about backpropagation & algorithm.
Machine learning is a scientific discipline that explores the construction and study of algorithms that can learn from data. Such algorithms operate by building a model from example inputs and using that to make predictions or decisions, rather than following strictly static program instructions. Machine learning is closely related to and often overlaps with computational statistics; a discipline that also specializes in prediction-making.
