Play around with i-Ball who uses a trained classifier to guess whether you're happy or sad from the way you look.
Here is a tutorial to get you started:
Step 1: Download the project. If you have not trained an image project that can recognize emotions, you can
use this data and train a new model.
Use the categories "happy" and "sad". Try to use your own pictures to train the model as well.
Step 2: After training your model, write down your API key and the model name to use in the starter project you downloaded.
