", Berner, Christopher, et al. preprocessing step. Objects have the potential to provide a compact, causal, robust, and generalizable To achieve efficiency, the key ideas were to cast iterative assignment of pixels to slots as bottom-up inference in a multi-layer hierarchical variational autoencoder (HVAE), and to use a few steps of low-dimensional iterative amortized inference to refine the HVAE's approximate posterior. Use only a few (1-3) steps of iterative amortized inference to rene the HVAE posterior. 0 representations. 24, Transformer-Based Visual Segmentation: A Survey, 04/19/2023 by Xiangtai Li There was a problem preparing your codespace, please try again.
