We introduce a pipeline for manifold learning in the hologram domain. A traditional autoencoder architecture is employed to compress and reconstruct complex holograms. The pipeline utilizes MNIST data and demonstrates consistent shape reconstruction. The latent vector representation of the hologram exhibits well-separated manifolds, successfully capturing similarities between numbers.
