Handwritten Digits Recognition Using CNN in Keras

Trained a model on MNIST handwritten digit database using CS231N in Keras.

Also implemented a GUI app to allow users to draw their own digit to test the model.

Training App

requirements

numpy
tensorflow
keras

run training

1. Edit the config in training_app/config.py if necessary
2. Run digitrecognition.py

result

0.9862 accuracy in 3 epochs

GUI Inference App

By utilizing trained model, we can predict given any images Here is an simple GUI application implemented in Django, which allows you draw a digit and run the prediction.

requirements

numpy
tensorflow
keras
pillow
django

run inference app

1. cd to gui_inference_app
2. make sure packages are installed correctly
3. python manage.py runserver
4. Open http://127.0.0.1:8000 in your browser
