lunch suggestion service based on past experience
I used Random Forests to predict the meal for the next 5 days based on data from the past 12 months. If you run node index.js you'll get a basic suggestion for tomorrow's lunch.
As I wanted to tweak the different options for the model, I created a UI for adjusting the parameters. Run node server.js to run the server, and visit http://localhost:8080 to get a suggestion and tweak the features and input parameters.
