Convolutional Neural Nets Explained and Implemented in Python (PyTorch)

Convolutional Neural Networks (CNNs) have been the undisputed champions of Computer Vision (CV) for almost a decade. Their widespread adoption kickstarted the world of deep learning; without them, the field of AI would look very different today.
Rather than manual feature extraction, deep learning CNNs are capable of doing image classification, object detection, and much more automatically for a vast number of datasets and use cases. All they need is training data.
Deep CNNs are the de-facto standard in computer vision. New models using vision transformers (ViT) and multi-modality may change this in the future, but for now, CNNs still dominate state-of-the-art benchmarks in vision.
In this hands-on video, we will learn why this is, how to implement deep learning CNNs for computer vision tasks like image classification using Python and PyTorch, and everything you could need to know about well-known CNNs like LeNet, AlexNet, VGGNet, and ResNet.

Thanks for the video. I can't find the link to the notebook in the video description, has it been removed?

[@blueaquilae]

Still a pleasure to watch your explanations. It help learning fast and apprehend concepts quickly. Wish you merry Christmas.

[@jamesbriggs]

Thanks Robert, enjoy the holidays!

[@PrimaryKenophobia]

I wanted to thank you--your series have helped out immensely--Please keep up such stellar work! Cheers!

[@jamesbriggs]

Thanks, will do!

[@AlessandroOrlandi83]

Oh I really am trying to understand this better. Thank you very much, it seems this video is clarifying a lot! Very good explanation thanks!

[@cego669]

Your explanation was very clear and helped me a lot, sir. Thank you!

[@sm-pz8er]

Very complete educational video. Thank you very much. I really enjoyed it

[@AI_Financier]

thanks for the video, why you chose pytorch for the implementation, Keras seems much easier?

[@user-uf2fk8eq3l]

e.g if I want to take a reference image and retrieve all the information within the image I can do it with CNN correct if I am wrong, moving forward with the question which is now since I have the information like histogram color palette latitude etc now I want to superimpose that on an input image, what should I do in order to do that its a personal project I work on short films and I am looking to make an Ai to help me in my color grading

[@pavanreddy4611]

incredible visualization 💯 Thanks for creating this kind of informative videos Appreciate your efforts @James Briggs

[@jamesbriggs]

Glad to hear it helps :)

[@sebest2k]

thanks for the great content!

[@zappist751]

BEST EXPLANATION EVERRRRRRRRRRR

[@farhanfaizal9437]

Where can i find the code?

[@meenakshichippa260]

Excellent!

[@jameshopkins3541]

FIRST YOUR CODE FOR 1D. AND 2D CONVOLUTION

[@thomasmeta2711]

awesome I get the stuff better here than in Cal lectures lmao

[@zappist751]

BRO IS A WALKING W LMAO

[@meenakshichippa260]

Even a high school student can understand what is CNN if student watch this.
