Digit Classifier app

View the deployed application here: https://xgb-digit-classifier.herokuapp.com/

This repo demonstrates how to build a classifier using

• mnist dataset: https://keras.io/api/datasets/mnist/
• ensemble classifiers (random forest, xgboost)

Important files:

• initial-model-training.ipynb: preprocess the dataset, train the models
• optimization: this folder contains alternative versions of the trained models, using gridsearch
• rf_grid_model.tar.gz: this is a compressed file containing the pkl file because the original was too large for github.

I was inspired by these other apps:
