This space lets you compare image classification results of identical architecture (WideResNet-2-28) models. The training of one of the models was improved
by using AdaMatch as seen in the example on [keras.io](https://keras.io/examples/vision/adamatch/).
The base model was only trained on the MNIST dataset and shows a low classification accuracy (8.96%) for a different domain dataset like SVHN. The AdaMatch model
uses a semi-supervised domain adaption approach to adapt to the SVHN dataset and shows a significantly higher accuracy (26.51%).
