Product Category ML Classification Web App Service (ML-as-service)

The developed model has achieved the highest test accuracy of 99.812 % and 0.998 test F1-score.

The notebook codetemplate/notebooks/EDA.ipynb contains the data exploration and analysis. The modeling, experiments, training, and evaluation of the algorithms are explained in the codetemplate/notebooks/Modeling-Training-Evaluation.ipynb notebook.

The webapp is built on Flask framework which takes user input on the go and returns a predicted category and predicted probability.

codetemplate directory contains the source files, the unittests, the flask webapp, ipynb notebooks & web html, results for the project.

Instructions:

1. Create a virtual environment such as conda or virtualenv

conda create --name productClass python=3.6

2. Install python dependencies using pip from the requirements.txt file

conda activate productClass
pip install -r requirements.txt

3. Run the unittests in the operations/tests/ in IDE to check if everything is alright. Make sure to define the exact project root path in the webapp/app.py for `operation/tests/unit/test_api.py'.
4. Run the train.py file to run the experiments and save trained models and the result files.
5. Start the flask web app by running the webapp/app.py.
