Hi, @m-gopichand , could you please share the Colab file or .ipynb for the same? Maybe we can collaborate if you find it good.

Hi, @prakharguptaujjain here is the link for collab file that i am currently working on , in this pull request the model i have used is a bit complex , and it is unfit for real world use because of its inferencing time.

The model in the PR use 3 features 'User agent', 'IP address', & 'Text'
The model's in colab file take only 'User agent' as feature , we can run series of experiments with this feature if the model accuracy is good then we can add other features later.

Hi @m-gopichand , why did you close it? or was only by deleting your branch? We are still testing this one. Sorry for the delay.
