Typo correction: At 14 minutes 45 seconds, the last index on the bias vector is n, when it's supposed to in fact be a k. Thanks for the sharp eyes that caught that!
For those who want to learn more, I highly recommend the book by Michael Nielsen introducing neural networks and deep learning: goo.gl/Zmczdy
There are two neat things about this book. First, it's available for free, so consider joining me in making a donation Nielsen's way if you get something out of it. And second, it's centered around walking through some code and data which you can download yourself, and which covers the same example that I introduce in this video. Yay for active learning! github.com/mnielsen/neural-networks-and-deep-learning
I also highly recommend Chris Olah's blog: colah.github.io/
For more videos, Welch Labs also has some great series on machine learning: youtu.be/i8D90DkCLhI youtu.be/bxe2T-V8XRs
For those of you looking to go *even* deeper, check out the text «Deep Learning» by Goodfellow, Bengio, and Courville.
Also, the publication Distill is just utterly beautiful: distill.pub/

— Animations largely made using manim, a scrappy open source python library. github.com/3b1b/manim
If you want to check it out, I feel compelled to warn you that it's not the most well-documented tool, and has many other quirks you might expect in a library someone wrote with only their own use in mind.

If you want to contribute translated subtitles or to help review those that have already been made by others and need approval, you can click the gear icon in the video and go to subtitles/cc, then «add subtitles/cc». I really appreciate those who do this, as it helps make the lessons accessible to more people.

The astonishingly real virtual baby that laughs, cries — and learns | Mark Sagar | TEDxChristchurch
This talk was given at a local TEDx event, produced independently of the TED Conferences. In this jaw-dropping talk, Academy Award winner Dr. Mark Sagar demonstrates his Baby X: a virtual baby that laughs, cries, and learns, driven by a complex series of brain, neural and somatosensory models.
Academy Award winner Dr. Mark Sagar is the director of the Laboratory for Animate Technologies at the Auckland Bioengineering Institute, where his interest is in bringing digital characters to life using artificial nervous systems to empower the next generation of human computer interaction. His laboratory is pioneering neurobehavioral animation that combines biologically based models of faces and neural systems to create live, naturally intelligent, and highly expressive interactive systems. Mark previously worked as the Special Projects Supervisor at Weta Digital and Sony Pictures Imageworks and developed technology for the characters in blockbusters such as Avatar, King Kong, and Spiderman 2. His pioneering work in computer-generated faces was recognized with two consecutive Scientific and Engineering Oscars in 2010 and 2011. Dr. Sagar holds a Ph.D. in Bioengineering and is a recipient of the University of Auckland’s 2012 Distinguished Alumni Award.
About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
