Handwritten digits recognition

This a Flask web app to predict handwritten english capital letters and digits using a deep convolutional neural network built with Keras and trained on the NIST and MNIST dataset.

Live demo : https://alpha-digit-recogn.herokuapp.com/

Train the model

To re-train a different model or see the existing model, check the training notebook

Test the app locally

(remember to remove the "-cpu" from tensorflow-cpu in requirements.txt)

cd app/

pip install -r requirements.txt

python app.py

Deploy the app to heroku

First of all make sure you have a heroku account and heroku CLI installed

Then just use the following commands from the root of the repository

heroku login

heroku create <your-app-name-here>

Now we are going to push only the app folder to heroku, since the other files are irrelevant for production

git init
git commit -am "1st commit"
git subtree push --prefix app/ heroku master

If any edit is done, push it again-

git add app/
git commit -am "<Commit Message>"
git subtree push --prefix app/ heroku master

And That's it ! The app is now running on the cloud and available for anyone to check.
