The world's best video explaining neural networks, deep learning, gradient descent and backpropagation

image


Videos from 3Blue1Brown are strikingly clear and concise. I did not succeed in making a synopsis of video lessons on neural networks, because it would have been just a storyboard, and the special magic of the dynamics of the video is not easy to convey.



From the comments on past publications, it became clear to me that there are a large number of people who do not know about the channel, so I want to share four videos (+ Russian subtitles and dubbing) and save time for schoolchildren, parents and teachers so that they can have quick access to the channel itself. interesting and high-quality explanation of one of the most important topics of our time.
