List of learning Materials for Deeplearning (free)!!!

As we know that deeplearning is currently a hot topic in the field of technology . Deeplearning comes under a section of machine learning which further is a branch of AI (artificial intelligence). Learning algorithms in deeplearning can be of three types: supervised / semisupervised/unsupervised learning .You may be thinking about what makes other artificial neural networks differs from it,right? So,for today we aren't going to discuss more about deeplearning and things inside it rather materials for learning it (as mentioned in the topic) Andrew Ng, the co-founder of Coursera is one of the best teacher in the field of AI . His machine learning course is one of the most enrolled course and it's free to enroll .
