[Fundamentals of Machine Learning and Neural Networks]What is the main difference between forward diffusion and reverse diffusion in diffusion models ofGenerative AI?

A. Forward diffusion focuses on generating a sample from a given noise vector, while reversediffusion 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 togenerate samples from noise vectors
D. Forward diffusion focuses on progressively injecting noise into data, while reverse diffusionfocuses on generating new samples from the given noise vectors.

Answer: D

[Experimentation]You have developed a deep learning model for a recommendation system. You want to evaluate theperformance of the model using A/B testing. What is the rationale for using A/B testing with deeplearning model performance?

A. A/B testing allows for a controlled comparison between two versions of the model, helping toidentify the version that performs better.
B. A/B testing methodologies integrate rationale and technical commentary from the designers ofthe deep learning model.
C. A/B testing ensures that the deep learning model is robust and can handle different variations ofinput data.
D. A/B testing helps in collecting comparative latency data to evaluate the performance of the deeplearning model.
