06. 1x1 Convolution Quiz Solution

The correct use is tf.layers.conv2d(x, num_outputs, 1, 1, weights_initializer=custom_init).

• num_outputs defines the number of output channels or kernels
• The third argument is the kernel size, which is 1.
• The fourth argument is the stride, we set this to 1.
• We use the custom initializer so the weights in the dense and convolutional layers are identical.

This results in the a matrix multiplication operation that preserves spatial information.
