Показать описание
Years of work down the drain, the convolutional neural network is a step change in image classification accuracy. Image Analyst Dr Mike Pound explains what it does.

This video was filmed and edited by Sean Riley.

I like the 'extensive' library of books he has on that shelf above and behind him

convolutional neural networks is one of those things that really needs some visuals, i find that it is really hard to 'grok' when you get it explained in a book or via speech but once you get a visual example it's kind of hilariously simple and scaringly plausible

This guy made all that really easy to follow. I admire his ability to explain such complicated things. He's really good at identifying and skipping over the irrelevant stuff, and focusing on the core problem/solution.

I guess the debate he mentions over whether neural networks will change everything, is settled now in 2024?

i love watching mike out of all the other ppl on this channel. this man just sounds right

Neat, I just did my bachelor thesis on convolutional neural networks. We built and trained a sign language interpreter that worked pretty well. I can affirm that neural networks are equal parts wisdom and witchcraft.

Not long ago, I read about a machine learning system that was able to classify planes, trees, and people in nearly live video, all without ever having any hard-coded feature sets. The math was way over my head (despite being a computer scientist, specialized areas can still stump me at times). Now I look back at it, and it was in fact a CNN being used! This was a few years ago now, but if they just started becoming popular in 2012, that makes sense.

Thank you for the higher-level explanation that allows me to understand it after all this time XD

For years down the line and look where we are now!
What a time to be alive!

This is by far the best video I've watched on CNNs and I've watched 4 others. It really describes the back propagation and image compression to a single dimension.

I could`t have explained it better, given the limitations of a youtube video. Well done computerphile!

I don't know why, but Dr Mike explains things so nice and clear. Thanks!

Couldn't but to observe WPF C# book, nice to see another one specialised in these two things

My friend had some project with ANN. And I have some project with image analysis. I never knew both can be linked with this technique! This might help me in my research!
Thanks Sean, thanks Dr Mike!

I just discovered this channel, saw a bunch viideos and didn't come across a single boring one.
