Scientists invented a machine that imitates the way the human brain learns new information, a step forward for artificial intelligence.The researchers have reported on Thursday.The system described in the journal Science is a computer model ‘that captures humans’ unique ability to learn new concepts from a single example,’ the study said.The system is a called a ‘Bayesian Program Learning’ (BPL) framework, where concepts are represented as simple computer programs.Researchers showed that the model could use ‘knowledge from previous concepts to speed learning on new concepts,’ such as building on knowledge of the Latin alphabet to learn letters in the Greek alphabet.
