Improved model based on MAML framework.

way	Improvement point
MAML
BMAML	A parameter-free reasoning model based on MAML is designed to solve the uncertainty problem of MAML model.
MT-net	Simplify the parameter space of MAML meta-learning model into a subspace composed of each layer of activation space, thus reducing the difficulty of fast learning.
TAML	Unbiased task unknowable experience is added to the initial model to solve the problem of poor performance of MAML framework in meta-training.
LEO	Combining MAML with metric learning, the model can quickly learn hyperparameters in low-latitude embedded space.
