10. AlexNet - CNN Explained and Implemented.

Here, We can learn the AlexNet CNN architecture with implementation details .

[@nastaranmarzban1419]

Hi, thanks for your really nice explanation, would you please explain a bit more why do we have 96 filters ?

[@setupyouryoutub]

Very simple way of explaining deep learning. Awesome playlist

[@ShriramVasudevan]

Thanks and glad u liked. Your comments keep me moving

[@ninadkulkarni9426]

Hello sir, it is very informative. I want to ask you is it possible for you to make a video for training Alexnet architecture with pre trained cifar 10 dataset with explaining on how to rescale the datasets from 32*32 to 227*227? This will be very much helpful

[@dawit_haile]

it is a good explanation in a simple way. Thank you.

[@ShriramVasudevan]

Thanks and glad you liked it

[@nevillechristopherraja3470]

hello Shriram, you have explained very well.. I have a question, the conv layer 2 has a padding of 2 as per the architecture but I see you have mentioned the padding as 'valid' for this layer, could you kindly clarify this? am I missing something here?

[@technologyhunter2460]

Nice effort, Appreciated!

[@subashsi9420]

Your, voice is similar to Ravi Ashwin. Great explanation

[@ShriramVasudevan]

Oh ho...thanks buddy..

[@afiatasnim8848]

u can train this AlexNet in tensorflow. but tensorflow won't provide pretrained weights for AlexNet. only pytorch will provide that.

[@keerthanaag8561]

does the table value change?? does the stride and image size from the alexnet architecture table in the video remain the same irrespective of the input image??

[@menakaraman3374]

Thanks for the explanation in a simple way

[@KARTHIK-mm5uz]

Sir, it is very informative. thank you very much.
Sir at the second convolution layer it is said that the size is 27x27x256. But it will be 23x23x256 right. in the program output, it is correctly calculated but in all the slides available it is 27x27x256. There are corresponding changes in the following layers (ie. in the next layer it is 11x11 then 9x9 then 7x7 etc.

[@sp3519]

You have made it very easy to understand

[@ShriramVasudevan]

Thank you

[@anitanbhatt]

Nicely explain and very easy to understand

[@ShriramVasudevan]

Thanks

[@unggulprabowo1045]

Nice tutorial and demo sir, I want to ask about layer output. In this video and architecture output layer using 1000 classes, If our have classes 4, do we have anything ouput layer change 4 classes ?.

[@esraahamada4784]

did you know the answer because I have the same question ?

[@thepresistence5935]

Hey Bro, you told transfer learning, where is the weights for this. I think we are using only architecture of the AlexNet, how to apply weights

[@profdurgahere9007]

This is one of the best.

[@nsridevi8569]

Very informative and useful sir.... very used for my research.... can you explain the drawbacks of these pretrained models.... like googlenet, inception, resnet

[@suyogborkar6644]

Great explanation sir!!

[@ShriramVasudevan]

Keep watching

[@muslumyildiz5694]

thanks

[@ShriramVasudevan]

You're welcome!

[@user-eg7ll9hg4h]

can we change parameters like input size , layer , feature map , size , kernel size , stride , activation ? any of them changing any of them will change alexnet architecture ? is it necessary to use same parameters which described in video to use this architecture namesd as alexnet ? If i change parameters it will be also called as alexnet ?

[@keerthanaag8561]

lemme know if you have found the answer

[@djjohny19]

Sir, thank you very much!

[@ShriramVasudevan]

Thank you

[@hasinamoideen584]

clearly explained !

Thanks hasina

[@aritraroy4275]

You didn't use batchNormalization or according to paper Local response Normalization

[@ihebdhouibi5132]

can you please share the code of AlexNet, it would help alot

[@ShriramVasudevan]

I will upload in GIT tomorrow..username shriramkv

Very nicely done

[@parthdedhia4182]

Hey, thanks for the explanation.
Regarding the input dimension of the AlexNet network, I tried implementing it in TensorFlow and only works if the size is 227 x 227. But Many of the literatures following them have made use of different dimensions. Like SPPNet paper says its 224 x 224 x 3, and R-CNN paper uses 227 x 227. Please can you explain me as to what should be believed.

[@ShriramVasudevan]

To my knowledge... it should work with any dimension. There is no hard rule about the dimensions bro.

[@saikrishnadas666]

The larger the image dimension, the more time it's gonna take for training and inference!

[@amankushwaha8927]

Is it possible to build the entire model without using the library?

[@ShriramVasudevan]

Yes. But, bit challenging

[@rohitborra2507]

this is the best I have found on internet but you would have implemented with some example

[@ShriramVasudevan]

I have done that. Video follows shortly brother.
