## Model Description
|
19 |
+
|
20 |
+
The vit-face-expression model is a Vision Transformer fine-tuned for the task of facial emotion recognition.
|
21 |
+
|
22 |
+
It is trained on the FER2013 dataset, which consists of facial images categorized into seven different emotions:
|
23 |
+
- Angry
|
24 |
+
- Disgust
|
25 |
+
- Fear
|
26 |
+
- Happy
|
27 |
+
- Sad
|
28 |
+
- Surprise
|
29 |
+
- Neutral
|
30 |
+
|
31 |
+
## Data Preprocessing
|
32 |
+
|
33 |
+
The input images are preprocessed before being fed into the model. The preprocessing steps include:
|
34 |
+
- **Resizing:** Images are resized to the specified input size.
|
35 |
+
- **Normalization:** Pixel values are normalized to a specific range.
|
36 |
+
- **Data Augmentation:** Random transformations such as rotations, flips, and zooms are applied to augment the training dataset.
|
37 |
+
|
38 |
+
## Evaluation Metrics
|
39 |
+
|
40 |
+
- **Validation set accuracy:** 0.7113
|
41 |
+
- **Test set accuracy:** 0.7116
|
42 |
+
|
43 |
+
## Limitations
|
44 |
+
|
45 |
+
- **Data Bias:** The model's performance may be influenced by biases present in the training data.
|
46 |
+
- **Generalization:** The model's ability to generalize to unseen data is subject to the diversity of the training dataset.
