Closes: #70

Describe the add-ons or changes you've made 📃

#Spam Detection Model Training Script:

• Added train_spam_model.py to download, preprocess, balance, and train a spam classifier using the SMS Spam Collection dataset.

• The script balances the dataset, trains a Naive Bayes model, evaluates it, and saves both the model and vectorizer as .pkl files.
  #Streamlit Web Interface:

• Added spam_detection_app.py, a user-friendly web app for spam detection.

• Users can input a message and get an instant prediction.

• The result is visually highlighted: green for not spam, red for spam, making it easy to interpret.
  #Data and Model Files:

• The dataset (SMSSpamCollection), trained model (spam_model.pkl), and vectorizer (spam_vectorizer.pkl) are included in the appropriate directory for reproducibility and deployment.

Move your file to models/ChatBot folder. Add need a video which display your code is running in Jarvis. (Means sidebar is verifying it)

Remove all comments & inline css styling. Use only streamlit elements.

For model files like pickle or joblib, you can checkout how movieReccommendationModel is setup.

Bro you need to setup your training notebook file on kaggle. And fetch and download the output model file over here as done in movie model

Connect me on discord, if you stuck in somewhere 👍

Could you plz raise a cleaned & new PR?
And don't forget to create your own branch apart from main.

Never commit directly to main branch!

[007-SARANG]

I'll send a PR today itself, but why did you close the issue? @Avdhesh-Varshney

[Avdhesh-Varshney]

Major Reason:

• I've not watched your committed branch earlier

Minor

• You can review your own pr, you have committed 45 files instead i need only 1 file (which will be automatically linked with jarvis, if keeping at right place by reading all the guidelines)
