Checklist

• My code follows the current project structure
• I have thoroughly reviewed and updated the requirements.txt file to include any new packages
• The predict.py file includes a properly implemented model_details() function, or the notebook contains this function to print a detailed model report. The model will not be accepted without this function, as it is essential for generating the necessary model details.
• I have added relevant tests (if necessary).
• I have added comments in the code where needed.
• This PR is submitted under Hacktoberfest.
• This PR is submitted under GirlScript Summer of Code (GSSoC-Extd).

Although you've added 3 models, they currently lack the necessary project structure and importantly a form page.
Please refer to docs/tutorial and docs/project-structure for guidance. Feel free to reach out if you have any questions.
