This sections deals with building a CNN to identify handwritten mathematical symbols. We're going to use the HASYv2 dataset. This contains 168,000 images from 369 different classes where each represents a different symbol. This dataset is a more complex analog compared to the popular MNIST dataset, which contains handwritten numbers.
The following diagram depicts the kind of images that are available in this dataset:
And here, we can see a graph showing how many symbols have different numbers of images:
It is observed that many symbols have few images and there are a few that have lots ...
