OCR-lite

A simple Python Flask app to allow users to write a digit on a canvas, and a model will analyze and output the predicted number. Amazon S3 is used for storage of models and parameters.

Web app taken down due to Heroku ending their free plan.

Models available:

1. Convoluted Neural Network (CNN) built using TensorFlow's Keras Layers, made up of:
   1. Conv2D(filters=16, kernel_size=(5, 5), padding='same', activation='relu', input_shape=(28, 28, 1))
   2. MaxPooling2D(pool_size=(2, 2))
   3. Conv2D(filters=36, kernel_size=(5, 5), padding='same', activation='relu')
   4. MaxPooling2D(pool_size=(2, 2)),
   5. Dropout(0.25)
   6. Flatten()
   7. Dense(128, activation='relu')
   8. Dropout(0.5)
   9. Dense(10, activation='softmax')
2. sklearn's Logistic Regression
