Smile detection applications are countless from activating a camera shutter automatically, enhancing human-robot interaction, to being incorporated into assistive communication devices for people with disabilities. Using deep learning convolutional neural network algorithms, a smile detection algorithm with an accuracy of 89% was achieved!

As a project I created Dad Jokes …

A Convolutional Neural Network (CNN) is an algorithm which can take in an image, assign importance (learnable weights and biases) to various aspects/features/filters in the image and be able to differentiate one from the other.

The architecture of a CNN can be thought to be similar to that …
