Web17 mei 2024 · In this short post, we will take a look at variational lower bound, also referred to as the evidence lower bound or ELBO for short. While I have referenced ELBO in a previous blog post on VAEs, the proofs and formulations presented in the post seems somewhat overly convoluted in retrospect.

Web6 aug. 2024 · In this work, we propose Iterative Latent Variable Refinement (ILVR), a method to guide the generative process in DDPM to generate high-quality images based on a given reference image. Here, the refinement of the generative process in DDPM enables a single DDPM to sample images from various sets directed by the reference image. WebTo compute the FID score between two datasets, where images of each dataset are contained in an individual folder: python -m pytorch_fid path/to/dataset1 path/to/dataset2 To run the evaluation on GPU, use the flag --device cuda:N, where N is the index of the GPU to use.
