Title: Object-Centric Learning with Slot Mixture Models. Abstract: Object-centric architectures usually apply some differentiable module on the whole feature map to decompose it into sets of entities representations called slots. Some of these methods structurally resemble clustering algorithms, where the center of the cluster in latent space serves as slot representation. Slot Attention is an example of such a method as a learnable analog of the soft k-Means algorithm. In our work, we use the learnable clustering method based on Gaussian Mixture Model, unlike other approaches we represent slots not only as centers of clusters but we also use information about the distance between clusters and assigned vectors, which leads to more expressive slots representations. Our experiments demonstrate that using this approach instead of Slot Attention improves performance in different scenarios achieving state-of-the-art performance in the set property prediction task.
