Small sample learning method for external memory and meta-learning based on attention guidance

The invention discloses a small sample learning method for external memory and meta-learning based on attention guidance, and belongs to the field of small-sample learning methods. According to the small sample learning method for external memory and meta-learning based on attention guidance, an inference network, an attention mechanism and a memory mechanism are combined for the first time; smallsample learning is carried out based on a meta-learning framework; an attention mechanism and an external memory mechanism are combined as a priori knowledge memory; a meta-learning framework and variational reasoning are combined to construct a recognizer; a priori knowledge memory combining an attention mechanism and external memory is effectively utilized; the influence caused by small samplesis compensated; moreover, by jointly learning an embedded function, mapping the representation to a potential space, storing the potential space as a value in an external memory, taking the content in the external memory as p
