u are such an awesome teacher! i am medical doctor with zero background to ML and your playlists are my go to place to grasp concepts before i dive in deep. Im grateful luv from ZIMBABWE
I've always struggled to understand pooling and this to-the-point explanation was the missing piece in the puzzle. I cannot thank you guys enough for the great work and taking the time to explain everything in so much detail. I owe so much of my knowledge of Deep learning to this channel
This is the best channel for machine learning on youtube! Thank you so much you really helped me out when I was studying for my exams. Keep up the good work!
Hey first of all I thank you for uploading this series, secondly "Deeplizard sounds cool and unorthodox" and lastly I liked the way you structured this entire series, short and crisp at the same time easy to understand and lot to learn for a newbie like me. Keep up the good work.
Having watched your great explanatory videos on CNN and Zero padding, I am actually going to give a thumbs up on every video of yours I see before I even start watching! :)
I have a question. During the video on zero padding, you indicated that padding was useful to maintain the size in the original matrix. In your example in this video you include padding='same' on both of your Conv2D layer. But then you include a MaxPooling2d layer which cuts in the matrix from 20x20 to 10x10. This seems to negate or contradict the benefits of the padding='same' on the Conv2D layers. Please explain why keeping the original size of the matrix is good for the Conv2D layer, while reducing the original size of the matrix is good for the MaxPooling2d layer. Thanks!
When doing a convolution operation, if not using padding, then the data at the edges of the images will be completely thrown away and lost. To prevent this data loss, we use padding. Max Pooling, on the other hand, will indeed reduce the image size, but it does not throw data away. The original data from the image is used in the pooling operation to create the lower resolution image. Let me know if this makes sense.
@@deeplizard I understand the reason for the padding (to not lose data), but I'm not sure I understand your comment regarding pooling "does not throw any data away". Given a 2x2 filter, it looks at 4 items in the image, and uses the max value, and throws the other 3 away. So we go out of our way (padding) to lose as little as possible with the Conv2D operation, just to lose 75% of the image with the polling operation. everyone does it this way, so I know it is right. I simply can't wrap my mind around why this is not an issue.
You made something that is supposed to be complicated and difficult... easy. Mind making a guide on quantum computing next? xD Fantastic work! Thank you
I don't think I've ever seen a youtube channel that beautifully sums up DL/ML concepts in a way that idiots and master coders can understand. I am genuinely disappointed that I didn't find your channel before I spent ages on reddit/stackoverflow! Hahah +1 Sub, Keep up the good work from all of us here in the comments!
Some questions: -does it make sense to have a grid of Y x Z, where Y Z, or/and the stride be different of any of those 2? -what happens if in the edges of the image we don't have a full block (remainders)? Do we still max it?
Great video! I have a question though. Is it a standard procedure to have a max pooling layer after every convolution layer? Furthermore, how does one decide whether to put a max pooling operation after a conv layer and in which cases should we not put a max pooling layer after a conv layer?
Thanks, ivzlccs! A Flatten() layer transforms the output from the previous convolutional layer into a 1D tensor so that it can be provided as input to the following Dense() layer. The two videos on learnable parameters in a CNN below may be helpful as well. There, when transitioning from the convolutional layer to the output layer, we discuss the flatten operation. th-cam.com/video/gmBfb6LNnZs/w-d-xo.html th-cam.com/video/8d-9SnGt5E0/w-d-xo.html
@@deeplizard Can you kindly also explain what dense layer does? The explanation that i have is that it connects layers but why would you have unconnected layers in the first place?
Do you know that I love you? thank you veeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeerrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrryyyyyyyyyyyyyyyyyyyyyyyyyyyyy much.you're the best.

Thanks, Daniel! We did go to university in the US, but we've graduated already :)
These videos are more useful than half a year of a university course on neural networks. Thanks for making them!
The Way you explain and then end up with an example of code it's really nice way to grasp!!!
I beg you! Keep making these videos. Your videos just light up my inner neural network.
0:19 What is Maxpooling?
5:42 Why do we use Maxpooling?
7:06 Example for other types of pooling
7:28 How is it done on code?
Awesome explanation!
Added to the description. Thanks so much!
I love the "Hey, what's going on, everyone?" at the beginning. :)
Great explanations, very clear and concise.

Really Nice Explanation. TNX
My new favorite channel. It has saved me at times in my undergrad
I'm blown away how good these explanation are!

perfectly explained... thanks much
extremely simple and easy to understand. Love it. Thank you.
thank you soooo much!!!! this was very hard for me to understand
Now this is as simple as it can be explained. Great work.
this is the best explanation video i have ever heard in my life.
Probably the most intuitive explanation I have ever seen =)
thanks for this video, it was super helpful !
thank you, really nice explaination
thank you very much for this clear and helpful explanation.

🤦😅
Well explained
This is very informative!

very nice visualizations...why is it so underrated..?
Thanks, akshay! Not enough people know about deeplizard. Help spread the word! :D
Great video, on the deeplizard site MaxPooling2D() is missing a comma at the end FYI
Good eye, thanks! Just corrected it on the site.

great articulation! thank you..
Great videos! easy to understand .It would be more understandable if the operations and coding part are zoomed .
Thanks for the feedback, Akanksha. In later videos, the font size is increased, and I zoom in on the code :)
good explanation..
Thanks for more videos. Great
No problem, Raju! Thanks for keeping up with the new releases!

What software do you use to make the animations, such that in the minute 3:09 moving the filter? Thanks.
and thank you for the clear explanation!
You're welcome, Abimael! The software is called Camtasia (link below).
