## Model description
|
13 |
|
14 |
+
This is an image classification model based on a [WideResNet-2-28](https://arxiv.org/abs/1605.07146v4), trained using the [AdaMatch](https://arxiv.org/abs/2106.04732) method by Berthelot et al.
|
15 |
+
|
16 |
+
The training was based on the example [Semi-supervision and domain adaptation with AdaMatch]('https://keras.io/examples/vision/adamatch/') on keras.io by [Sayak Paul](https://twitter.com/RisingSayak).
|
17 |
+
|
18 |
+
The main difference to the training in the keras.io example is that here I increased the number of Epochs to 30, for a better target dataset performance.
|
19 |
+
|
20 |
|
21 |
## Intended uses & limitations
|
22 |
|
23 |
+
AdaMatch attempts to combine *semi-supervised learning*, i.e. learning with a partially labelled dataset and *unsupersived domain adaption*, i.e. adapting a model to a different domain dataset without any labels.
|
24 |
+
|
25 |
+
So it actually performs **semi-supervised domain adaptation (SSDA)**.
|
26 |
+
|
27 |
+
The model is inteded to show that AdaMatch is able to carry out SSDA, with a accuracy on the target domain (SVHN) that is exceeding or competitive with other methods.
|
28 |
+
|
29 |
+
### Limitations
|
30 |
+
The model was trained on MNIST as source and SVHN as target dataset. Thus, the classification performance on MNIST is very good (98.46%), while the accuracy on SVHN is "only" at 26.51%. Compared to the training of the same architecture without AdaMatch, this still is about 17% better
|
31 |
|
32 |
## Training and evaluation data
|
33 |
|
34 |
+
### Training Data
|
35 |
+
The model was trained using the [MNIST](https://huggingface.co/datasets/mnist) (as source domain) and [SVHN cropped](http://ufldl.stanford.edu/housenumbers/) (as target domain) datasets. For training the images were used at a resolution of (32,32,3).
|
36 |
|
37 |
+
Augmented versions of the source and target data were created in two versions - weakly and strongly augmented, as written in the original paper.
|
38 |
|
39 |
+
### Training Procedure
|
40 |
+
This image from the original paper shows the workflow of AdaMatch:
