I think these are the most underrated videos on deep learning. The concepts are explained so well. Please keep making more videos.
I had previously uploaded this video but code in that video had some issues handling imbalance in the classes. I've fixed those issues and recorded this new video. Thanks Abhishek and few others who pointed out the issues.
Hello, sir I was trying to seach "feature engineering codebasics" your playlist was not coming .After that I have to go to your youtube channel and from there I viewed that playlist.Please check if that problem is facing my me only .
Thanks for making the video again. I appreciate the work you do for everyone.
@@mudassaraliansari8969 Same is happening with his machine learning playlist. Its not visible on his playlist but if i search it on search bar, It appears. Very strange.
Oh thank god, finally someone who explains well AND covers the topic in enough depth to be useful.
Underrated channel tbh..He needs more recognition. Thanks a lot for supporting us.
You are awesome, this is first actual slow enough and easy BERT starting video i've seen and suited me very much!
Thanks. Very well explained. You explains the hidden insights which clears all doubts and make concepts simple and easy to understand.
Thank you so much for your videos! You don't know how much you have helped me. I was really scared to dive into transformers but you have made it very easy to understand.
As soon as I watched this video I subscribed your channel. The videos and tutorials are super useful. Thanks for sharing these valuable knowledge with us for free :)
I am getting No matching distribution found for tensorflow_text==2.12 error while installing tensorflow_text using pip.Could you please help on this.Thank you
sir i have seen your Complete Data analyst roadmap and Data Science roadmap video.I was very amazing.I request you to upload a video on Complete roadmap for learning DSA with resources.so that it can help students like me in placements.Thank You
Thank u so much, need more videos related to NLP, need more advanced concepts/projects in NLP area
yes I will start working on NLP soon
can we use the hidden layers(only CLS) generated from the bert model as a features , to train the tfdistilled bert for binary classification task
What about using sequence_output vectors as input to LSTM as it needs 3D input?
Thanks for the video.can you please let us know,how can we proceed if the text input is high (more no of tokens)
Hello...can you please confirm if removal of stopwords,numbers,stemming etc is required in this case ?
Thank you so much for your videos! But i have a doubt since balancing the data in multi label classification doesn't help cause words have similar meanings ,what can be done?
Hi, Last dense layer throws an error if classes more than 2, example spam, ham ,social. How to set output (Dense) (None, 1) 769 dropout[0][0] to output (Dense) (None, 3) 769 dropout[0][0]
Please Sir, how can I use BERT Embedding as input to Embedding layer of an LSTM.
Thanks
Thank you very much! You really helped me!
How do we save the model & use in a another application ? It throws an error when I load the trained model from saved path.
Can a BERT model be used for a task like scoring resumes according to job description ?
How can I download the datasets which is used in this video? Can you give me the link?
When I am using bert,then it is not necessary to remove stop word from corpus?
@codebasics what if I have more then one category who to deal with that
Bro watching these tutorials make me want to blow my brain up with the amount of times you mention your previous videos.
wonderful!! but... what if we have 3 or more categories instead of just 2? Thanks a lot
Thank you so much for this video. This is very helpful for my master's project. Please the model you built in the video, is it a fine-tuning of the last layer of BERT or completely retraining all BERT layers?
Hi sir, Thank you for this amazing video. I have followed your video and used bert model for text classification and the accuracy of my model is very low. Can you help me
Sir I have downloaded BERT encoder and preprocess as a rar file from the link. Please tell me how to use them in the coding? I dont want to load the files through http url but from the files i downloaded. Would be of great help, Thank you!
Please help,
How can I input SMOTE for oversampling in this model?
Great video. Very easy to follow.
Hi, if I have multiple categories that I want to sort my data into (right now in this video there are 2: ham and spam) how might I adjust this model? The sigmoid activation function would not be usable correct?
Thanks for the video, I am getting an error saying failed to covert Numpy array to Tensor.
Hi, thanks for the Vid.
Is it possible to make that code run with and AMD GPU ?
The code do not work now.
Do you have another code please
i need it for university project
@@muhammadalzabibib2650 I need tooo
if my task is classification with Bert and RNN-specially BiGRU then what output of BERT I need to use ? Pooled or sequential? If I am using Pooled then I am getting error of dimension as rnn requires 3d tensor. Please help with it.
Which algorithm we are using for the text classification here? Can anyone tell me please?
Very useful video, thanks a lot!
is it possible to add custom tokens or synonyms to the Bert model? for example, Ｊ=J, Ｑ=Q, A = Apple, something like these. if it's possible, how to do it on Tensorflow?
Very useful video. Thank you so much.
anyway, can we convert this transfer learning to tflite format?
Well Explained ..Thank you for this wonderful explanation 👏
Glad you liked it!
Sir How do I download the dataset?Can You provide the link
when running this code
return bert_encoder(preprocessor)['pooled_output']
I'm getting an error :

Can you do Spoiler Detection with BERT ? I have been trying for some time but I am not able to.
helo sir, I want to know one thing for code mixing language like hindi in english letter does Muril BERT understand this hinglish which is english letter wriiten hindi pronounciation
sir for getting embed values u explained grapes and banana r similar, then when we relate it to mails, it mean that the mails which r coming r not similar to his current situation and that result to spam
Is there much to adjsut for multiple classification?
Great video. I am facing an issue installing tensorflow_hub: cannot import name 'deserialize_keras_object' from partially initialized module 'keras.saving.legacy.serialization' . Any thoughts?
Perfectly Expalined! Thanks a lot.

I knew Jeff Bezos and banana has a lot in common 🤣 Great video btw
How can we apply BERT on multiclass classification problem?
Sir If it is a multi class classification the where should I change the code
what i have to search in kaggle to get that dataset
Hi, great video! What would you to to fine tune this model? :)
Thanks for this nice tutorial !
Using same code, I got error "Cast string to float is not supported
[[node binary_crossentropy/Cast (defined at :1) ]] [Op:__inference_train_function_85259]
Function call stack:
train_function". I tried to solve error on my end but did not.
Thanks for the video. You are amazing!
Thanks for the great explanation. Really heplful
Hi Sir,
Instead of your output I'm getting:
Keys : ['input_mask', 'input_type_ids', 'input_word_ids']
Shape : (1, 128)
Word Ids : Tensor("strided_slice_3:0", shape=(12,), dtype=int32)
Input Mask : Tensor("strided_slice_4:0", shape=(12,), dtype=int32)
Type Ids : Tensor("strided_slice_5:0", shape=(12,), dtype=int32)
Do you know why I would get this output?
Is there a code for NLP Model without labels (i mean Unsupervised ML) ?, i am struggling to find ;)
I can't find the dataset can someone help me
You are teaching in Nice manner. Can we have NER task Architecture explanation for Bert & How it is Working and some code for implementation of NER
very helpful，thank you！
sir what if i have multilabel dataset like 6 labels
Can you please show how to plot the loss graph?
Can you please show a real time deployment of a model like this on AWS
everything work fine but when i m trying to fit the model it is giving me error as " ValueError: Failed to convert a NumPy array to a Tensor (Unsupported object type float)." I m stuck so bad anyhelp would be appreiciatable, thank you in advance
can you provide me the link of this data set
Great Video! By the way, a small typo, the percentage of spam is 747/(4825+747),
great video, thanks sir!
Thanks for sharing this nice well explained concept.

can you please tell me what's wrong ?
very nice Explanation, very helpful to me. Thanks. Can You make Video on ELMO Word embedding?
Hello. I remember you said that, NN is not suitable for working with text, as some disadvantages. why you used NN as a model here?.
please do more in-depth stuff on NLP!!
What's the point of inputs classes (spam/ham) here ? why you didn't use them ?
very nice video sir. Thanks
I have almost 1200+ labels, It is a good idea to use this model?
Can you share the dataset link
i copied your steps but the model is extremely slow how could i fix it .. it takes hours and hours;(?
Thanks for these great videos. Quick question - I have watched your whole maching learning+deep learning series so far, and I'm wondering: are there ways one can tell whether the models discussed in the ML videos (linear regression, logistic, random forest, etc) versus a neural network is better suited to a situation? Or can you only know by testing all of them out, like in a GridSearchCV? Could you perhaps discuss this in a video?
Neural networks are best for unstructured data (images, text, audio, video) and when the training dataset is huge. For structured data statistical models are preferred.
@@codebasics Thanks so much for replying and for selflessly producing these videos.
Thank you so much sir pls where can I find the code?
If the value is more than 0.5, how can it be a spam email? Why can't they be ham email?
Hey, thanks for the video. I was wondering at the end for inferences, you get decimal values like 0.8 which leans towards "Spam". However, is there a way to specifically return "Spam" with like 80% confidence or something like that, instead of just the decimal values?
yes right a custom function like def funct(score): if score>=0.5 return (score*100,"spam") else return (100-score*100,"Ham")
@@aditya_01 or else we can use np.where function to classify spam and ham
dude you are awesome
Man, You are a legend!
Thank you sir for your valuable lectures. Can you direct me to one of your content about XLNet Model?
Thank you very much for the useful lesson. Can you tell me what the output format of multi-class text classification?
Simply add number of neurons as the number of classes in the last layer (in this video he used one, so change it), one-hot encode the classes, use a loss function that is used for multi-class classification.
how can i adapt the dense layer in the case of multiclass classification ?
You can set the activation function as 'softmax' instead of 'sigmoid' in the final layer of the model.
very interested
which data set
Thanks a lot for the video.
This is great for binary classification. Any idea on how to do the same when we have more than two classes? (e.g. science, technology, linguistics, other)
loss fn, will achange and softmax activation fn
sir, please make one video on named entity recognization using bert
