CoreML + SwiftUI demo App to demonstrate the potentiality of the SwiftCoreMLTools library (https://github.com/JacopoMangiavacchi/SwiftCoreMLTools) to fully create and train on iOS devices a Convolutional Neural Network for the MNIST dataset.
The MNIST dataset (Creator: Yann LeCun, Corinna Cortes) of handwritten digits, available from this page MNIST dataset, has a training set of 60,000 examples, and a test set of 10,000 examples. It is a subset of a larger set available from NIST. The digits have been size-normalized and centered in a fixed-size image.
It is a good database for people who want to try learning techniques and pattern recognition methods on real-world data while spending minimal efforts on preprocessing and formatting.
