Ein ResNet-34-CNN mit Keras implementieren
Die meisten bisher beschriebenen CNN-Architekturen lassen sich ziemlich einfach implementieren (auch wenn Sie normalerweise stattdessen ein vortrainiertes Netzwerk laden werden, wie wir noch sehen). Um den Prozess aufzuzeigen, wollen wir ein ResNet-34 mit Keras von Grund auf erstellen. Zuerst erzeugen wir eine Residual Unit-Schicht:
class ResidualUnit(keras.layers.Layer):
def __init__(self, filters, strides=1, activation="relu", **kwargs):
super().__init__(**kwargs)
self.activation = keras.activations.get(activation)
self.main_layers = [
keras.layers.Conv2D(filters, 3, strides=strides,
padding="same", use_bias=False),
keras.layers.BatchNormalization(),
self.activation,
keras.layers.Conv2D(filters, 3, ...
