[1707.03389] SCAN: Learning Abstract Hierarchical Compositional Visual Concepts


Compositionality is an inherent part of natural language. Researchers from DeepMind propose a model that can learn abstract hierarchical compositional visual concepts (a mouthful). Using an existing model (the beta-VAE) to learn disentangled representations from visual input, their model learns abstractions from a small number of symbol-image pairs, e.g. example images paired with the symbol "apple". Using logical operators (AND, etc.) the model then learns to compose these concepts. Blog post.
