How can Tensorflow be used to compose layers using Python?
TensorFlow allows you to compose layers by creating custom models that inherit from tf.keras.Model. This approach enables you to build complex architectures like ResNet identity blocks by combining multiple layers into reusable components. Understanding Layer Composition Layer composition in TensorFlow involves creating custom models that encapsulate multiple layers. This is particularly useful for building residual networks where you need to combine convolutional layers, batch normalization, and skip connections into a single reusable block. Creating a ResNet Identity Block Here's how to compose layers by creating a ResNet identity block that combines multiple convolutional and batch normalization ...
