Invertible convolution, also known as reversible convolution or bijective convolution, is a type of convolutional layer that allows for exact reconstruction of the input from the output. This is achieved by ensuring that the mapping from input to output and from output to input are both bijective, meaning that they are one-to-one and onto.
The main advantage of invertible convolution is that it enables reversible neural networks, which can be useful in applications such as generative modeling, where the ability to invert the mapping from output to input is important. Invertible convolutions have also been shown to improve the robustness of deep neural networks by reducing the impact of vanishing gradients and enabling better optimization.
In TensorFlow, invertible convolution is implemented using the tfp.bijectors.InvertibleConvolution layer. This layer takes an input tensor and applies a convolution operation to it, while ensuring that the mapping from input to output and from output to input are both bijective. The layer also includes trainable weights for the convolution operation.
Overall, invertible convolution is a powerful tool for building reversible neural networks and improving the robustness of deep learning models.
