Transfer Learning Using CNN(VGG 16)| Keras Tutorial|

In this tutorial I am going to show you how to use transfer learning technique on any custom dataset so that you can use pretrained CNN Model architecutre like VGG 16, ResNet 50, Inception V3 directly for your problem.
In this video I solve the problem of Skin Cancer classification into benign vs malignant using pretrained CNN Model.

Hi, How can we see the accuracy chart of the validation test set? How can we see the incorrect pictures in the test set? Thanks a lot

[@dishachakraborty9769]

I need help. I don't have separate train, test and validation data for my dataset on Kaggle.
The dataset only has 3 folders - Normal, Benign and Malginant which contain images but no subfolders for train and test.

[@syedzoofa8711]

Ur videos have helped me a lot.. Thank u

[@mohammedzia1015]

I have one question, the VGG16 model would have been trained for this type of Dataset ? I mean for the classes Benign and Malignant ?

[@reemalmijmaj3215]

This video save my life :)) Thanks a lot !!

[@plabmadeeasy]

You've got a subscriber!

[@sayansaha5348]

Thanks bhaiya can you please make a separate video for the prediction part only

[@kaouthergacem8135]

your video helped me a lot thank you

[@TitoWPurnomo]

I've run code with jupyter-lab but during training process always appears statement "the kernel appears to have died. it will restart automatically" . do you know the solution?

[@shivambaldha3914]

Very very useful for me , thank you :)

[@byDes]

Hello, this helped me a lot! I hope you could also make a tutorial for medical images using mobilenetv2

[@ashikroy4618]

Hi Nachiketa,
Thank you for your tutorials.
I am a beginner, and I am wandering why didn't you use Validation and Test, both of the datasets to evaluate your transfer learned model?
Thanks

[@swatimishra1555]

I am also not getting validation accuracy and loss because they n
have not to use a train test split. I really don't know how he is getting validation accuracy and loss for the model. Plz, include this in the code.

[@swatimishra1555]

Hi Nachiketa,
plz clear this doubt

[@leo7662]

​@@swatimishra1555when u r writing u just need to write validation split =0.2 that will automatically take 20% of our data as validation set randomly so u will get both validation loss and accuracy

[@vanshajgoel8783]

InvalidArgumentError: Graph execution error: -->Any idea why this error is coming ??

[@NachiketaHebbar]

Normally you get this error when there is a mismatch in the number of data classes that you defined in model and the one which you are actually giving it. Double check the input shape, target size , number of dataset folders and the number of output layers

[@sherin7444]

1 question.Lets say in my train file couple of images are not of 224*224 .How can we convert them to standard size

[@alexomelak4200]

Sir ,help me please? I was doing gray scale image classification using VGG16. their is an error when I update the code from
vgg = VGG16(input_shape=IMAGE_SIZE + [3], weights='imagenet', include_top=False) to
vgg = VGG16(input_shape=IMAGE_SIZE + [1], weights='imagenet', include_top=False). help me please

[@sagnikroy6405]

Thanks @Nachiketa . Really helped. One question , what does the .h5 extension is for?? Storing trained NNs??

[@NachiketaHebbar]

Yeah, it stores the model architecture and weights

[@komaldaoud3445]

how can we use grid search cv with model.fit??

[@rohit_mondal__]

Sir if you could explain the vgg.input thing we are putting in the inputs section of the model !

[@nikolaostziokas6847]

Great video. I have only one question. What are the dimensions of your training and test images? Do they have to be 224*224 before you import them into the algorithm?

[@shreypatel3782]

NO.

[@sherin7444]

VGG16 expects img size to be 224*224

[@bhavukthakur9501]

sir, when you do ImageDataGenerator step how many images we get?
Like, if we have 10 image in train dataset and we apply rotation_range, width_shift_range, height_shift_range=0.2 so we get 30 images or just 10 images?

[@OpeLeke]

Great Video, it's skin lesion dataset not skin cancer.

[@byDes]

Hi! How did you split the train, val, and test dataset?

[@sololife9403]

if you download the dataset from kaggle, you will find out that the train and test sets were already split for us. but i did not find val , though

[@pavantripathi1890]

Can you please show how to predict on a new image.

[@umanggupta1003]

Can you show end to end code with model.Predict() to verify the results?

[@bihanbanerjee]

thank you

[@leenaselvamani9065]

Can you help me if I try to fit my model it says kernel is dead what shld I do for this prblm

[@girimadhavchowdhury1281]

I could not able to resize my input into 224*224*3... Can any one help me on this

[@rakeshsahoo3711]

Can u apply k-fold cross-validation for this

[@anchalsharma6163]

Hloo sir can you help ke for plot graph

[@darshitavijayakumar2021]

I'm getting that the object is not callable . Please help me

[@hamzanaeem4838]

What if we don't use steps per epoch and validation steps ? Can we use model.fit only if we don't apply augmentation.

[@sagnikroy6405]

I guess YES, as the fit_generator is deprecated in the newest version of tensorflow or keras.

[@aninditasaha0307]

Hi... Can anyone send me the confusion matrix code for this prob?

[@vanillasky1842]

So if I'm using grayscale images,where should I make the changes?

[@NachiketaHebbar]

in the input shape. Instead of 3 as the depth of image, use 1.

[@Megh93]

getting error in model.fit_generator

[@jaideeppanwar2730]

hey.....can we make a gradio app on this ......i mean it will the same process ....that u showed in the earlier video ?

[@NachiketaHebbar]

Yes, you can. I had shown an inception model in that video, you can just replace that by this vgg model. It will work

[@saisingireddy2359]

💎🛐

[@rasanjalirathnayake8873]

Instead of classification do something related to deep learning with regression analysis please.

[@madhukanadeeshani6982]

Hi it's great .can you please share the code and link of the dataser

[@NachiketaHebbar]

Already there in the description

[@adarshrkr9355]

Bro when im doing prediction im only getting class 0 for all my test data
Any idea?

[@NachiketaHebbar]

If your test accuracy is good, then most probably the mistake you are making is in pre processing the input. For example, if while training you are rescaling the input or something else, then you have to do the same on an image before making predictions also.

[@adarshrkr9355]

@@NachiketaHebbar ok bro thankyou will try that out

[@simonegasparella1228]

Hi Sir, after training how can we make a prediction in one specific picture? Can you share the code ? Thanks
