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.

Yet most work on representation learning focuses on feature learning without even considering multiple objects, or treats segmentation as an (often supervised) preprocessing step. ", Zeng, Andy, et al. This paper theoretically shows that the unsupervised learning of disentangled representations is fundamentally impossible without inductive biases on both the models and the data, and trains more than 12000 models covering most prominent methods and evaluation metrics on seven different data sets. Large language models excel at a wide range of complex tasks. This paper introduces a sequential extension to Slot Attention which is trained to predict optical flow for realistic looking synthetic scenes and shows that conditioning the initial state of this model on a small set of hints is sufficient to significantly improve instance segmentation. The model, SIMONe, learns to infer two sets of latent representations from RGB video input alone, and factorization of latents allows the model to represent object attributes in an allocentric manner which does not depend on viewpoint.

This paper addresses the issue of duplicate scene object representations by introducing a differentiable prior that explicitly forces the inference to suppress duplicate latent object representations and shows that the models trained with the proposed method not only outperform the original models in scene factorization and have fewer duplicate representations, but also achieve better variational posterior approximations than the original model.
