Question 4

+2 marksOne correct option

Vector Quantized Variational Autoencoder (VQ-VAE) utilizes a discrete latent representation as opposed to continuous latent spaces used in traditional VAEs. One of the key components of a VQ-VAE is the codebook, which consists of a set of learnable vectors. What is the primary role of the codebook in VQ-VAE?

  1. A

    It performs the non-linear transformation of the input data to a higherdimensional space.

  2. B

    It regularizes the encoder by penalizing complex encodings.

  3. C

    It provides a finite set of vectors which the encoder’s outputs are mapped to,effectively quantizing the latent space.

  4. D

    It decodes the quantized vectors back into the reconstructed input space.
