Backpropagation explained | Part 2 - The mathematical notation

We covered the intuition behind what backpropagation's role is during the training of an artificial neural network.    • Backpropagation explained | Part 1 - The i...   Now, we're going to focus on the math that's underlying backprop. The math is pretty involved, and so we're going to break it up into bite-sized chunks across a few videos. We're going to start out in this video by first quickly recapping how backpropagation is used during the training process. Then, we'll jump over to the math side of things and open our discussion up by going over the notation and definitions that we'll be using for our backprop calculations going forward. These definitions and the notation will be the focus of this video. The math underlying backprop all relies heavily on what we'll get introduced to here, so it's crucial that these things are understood before moving forward. Lastly, we'll narrow our focus to discuss the several indices that the notation depends on. 🕒🦎 VIDEO SECTIONS 🦎🕒 00:00 Welcome to DEEPLIZARD - Go to deeplizard.com for learning resources 00:40 Outline 01:26 Backpropagation Recap 02:50 Definitions and Notation 07:20 Review 10:00 Summary 10:33 Collective Intelligence and the DEEPLIZARD HIVEMIND 💥🦎 DEEPLIZARD COMMUNITY RESOURCES 🦎💥 👋 Hey, we're Chris and Mandy, the creators of deeplizard! 👉 Check out the website for more learning material: 🔗 https://deeplizard.com 💻 ENROLL TO GET DOWNLOAD ACCESS TO CODE FILES 🔗 https://deeplizard.com/resources 🧠 Support collective intelligence, join the deeplizard hivemind: 🔗 https://deeplizard.com/hivemind 🧠 Use code DEEPLIZARD at checkout to receive 15% off your first Neurohacker order 👉 Use your receipt from Neurohacker to get a discount on deeplizard courses 🔗 https://neurohacker.com/shop?rfsn=648... 👀 CHECK OUT OUR VLOG: 🔗    / deeplizardvlog   ❤️🦎 Special thanks to the following polymaths of the deeplizard hivemind: Tammy Mano Prime Ling Li 🚀 Boost collective intelligence by sharing this video on social media! 👀 Follow deeplizard: Our vlog:    / deeplizardvlog   Facebook:   / deeplizard   Instagram:   / deeplizard   Twitter:   / deeplizard   Patreon:   / deeplizard   YouTube:    / deeplizard   🎓 Deep Learning with deeplizard: Deep Learning Dictionary - https://deeplizard.com/course/ddcpailzrd Deep Learning Fundamentals - https://deeplizard.com/course/dlcpailzrd Learn TensorFlow - https://deeplizard.com/course/tfcpailzrd Learn PyTorch - https://deeplizard.com/course/ptcpailzrd Natural Language Processing - https://deeplizard.com/course/txtcpai...
