AdaBoost

An Interactive Demo

Dataset

For this demo, we will be using the MNIST dataset, a collection of 70,000 handwritten digits.

Next ->

Each MNIST image is a pre-processed to be exactly 28x28 pixels and grayscale.

Next ->

To simplify this demo, we will focus only on classifying the digits 0 and 1.

Next ->

Classifier

stump

We will be using a stump as our classifier.
A stump finds an outcome using one condition.

Next ->

There are many conditions we can use to classify images. For this demo, we will use partition pixel intensity.

Next ->

Our stumps will first partition each image into two sets.

Next ->

The set with the highest average pixel intensity will determine the output.

Next ->

We will "train" stumps by trying 10 partitions and selecting the one with the most significant result.
