## Trening modelu
Do trenowania używano biblioteki Keras
### Pierwsze podejście model trenowany od zera (from scratch)
```
img_height=256
img_width=256
batch_size=128
epochs=30
```
```
layers.Rescaling(1./255, input_shape=(img_height, img_width, 3)),
layers.Conv2D(16, 3, padding='same', activation='relu'),
layers.MaxPooling2D(),
layers.Conv2D(32, 3, padding='same', activation='relu'),
layers.MaxPooling2D(),
layers.Conv2D(64, 3, padding='same', activation='relu'),
layers.MaxPooling2D(),
layers.Flatten(),
layers.Dense(128, activation='relu'),
layers.Dense(29,activation='softmax')
```
Zbiór testowy własny: 22% Accuracy
Zbiór testowy mieszany z Kaggle: 80% Accuracy

## Drugie podejście model VGG16
```
img_height=224
img_width=224
batch_size=128
epochs=10
```
Usunięto 3 wierzchne wartswy i dodano warstwy:
```
x = layers.Flatten()(vgg_model.output)
x = layers.Dense(len(class_names), activation='softmax')(x)
```
Zbiór testowy własny: 40% Accuracy
Zbiór testowy mieszany z Kaggle: ???% Accuracy
