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
