From Neurons to Networks
I would rate it as the one of the best videos I saw on how human brain works. MUST watch!!! It beautifully relates human brain with internet and talks about what should be done to strengthen different parts of ourselves.
Artifical Intelligence – Ted Talk
This is a great video that represents some real good visualizations on how brain works. It is however a talk (on TedTalk). I would recommend it as a MUST for those who are starting on neural networks.
Introduction to Neural Networks
This video beautifully represents neural networks including aspects of how do computer learns, errors & related adjustment (backpropagation technique), calculation of new weights based on old weights etc.
Introduction to Artifical Networks
This one is a good video from the perspective of understanding what is neural network. It demonstrates back propagation technique used in neural networks.
MIT Courseware: Neural Networks, back Propagation
This video represents academic perspective on neural networks including definition on what are neurons, axons etc.
