Researchers have created a computer model that captures humans' unique ability to learn new concepts from a single example. Though the model is only capable of learning handwritten characters from alphabets, the approach underlying it could be broadened to have applications for other symbol-based systems, like gestures, dance moves, and the words of spoken and signed languages. Recent years have seen steady advances in machine learning, yet people are still far better than machines at learning new concepts, often needing just an example or two compared to the tens or hundreds machines typically require. What's more, after learning a concept for the first time, people can typically use it in rich and diverse ways. Brenden Lake and colleagues sought to develop a model that captured these human-learning abilities. They focused on a large class of simple visual concepts -- handwritten characters from alphabets around the world - building their model to "learn" this large class of visual symbols, and make generalizations about it, from very few examples. They call this modeling scheme the Bayesian program learning framework, or BPL. After developing the BPL approach, the researchers directly compared people, BPL, and other computational approaches on a set of five challenging concept learning tasks, including generating new examples of characters only seen a few times. On a challenging one-shot classification task, the BPL model achieved human-level performance while outperforming recent deep learning approaches, the researchers show. Their model classifies, parses, and recreates handwritten characters, and can generate new letters of the alphabet that look 'right' as judged by Turing-like tests of the model's output in comparison to what real humans produce.

Perhaps this is another spin 0 particle such as a Higgs that decays into t tbar rather than toponium? The events distribution at the lowest m t tbar looks pretty broad. Can LHC distinguish toponium...
