Unsupervised multi-object representation learning depends on inductive biases to guide the discovery of object-centric representations that generalize. This model is able to segment visual scenes from complex 3D environments into distinct objects, learn disentangled representations of individual objects, and form consistent and coherent predictions of future frames, in a fully unsupervised manner and argues that when inferring scene structure from image sequences it is better to use a fixed prior. OBAI represents distinct objects with separate variational beliefs, and uses selective attention to route inputs to their corresponding object slots. We demonstrate that, starting from the simple assumption that a scene is composed of multiple entities, it is possible to learn to segment images into interpretable objects with disentangled representations.
