Question # 22

What is the main difference between forward diffusion and reverse diffusion in diffusion models of Generative AI?

Options:

A.  

Forward diffusion focuses on generating a sample from a given noise vector, while reverse diffusion reverses the process by estimating the latent space representation of a given sample.

B.  

Forward diffusion uses feed-forward networks, while reverse diffusion uses recurrent networks.

C.  

Forward diffusion uses bottom-up processing, while reverse diffusion uses top-down processing to generate samples from noise vectors.

D.  

Forward diffusion focuses on progressively injecting noise into data, while reverse diffusion focuses on generating new samples from the given noise vectors.

Question # 25

In neural networks, the vanishing gradient problem refers to what problem or issue?

Options:

A.  

The problem of overfitting in neural networks, where the model performs well on the training data but poorly on new, unseen data.

B.  

The issue of gradients becoming too large during backpropagation, leading to unstable training.

C.  

The problem of underfitting in neural networks, where the model fails to capture the underlying patterns in the data.

D.  

The issue of gradients becoming too small during backpropagation, resulting in slow convergence or stagnation of the training process.
