【Abstract】 Deep learning algorithms based on big data are becoming more and more perfect. However,how to solve the situation where the number of training samples is very small is a very important and challenging problem in the existing neural network research field. Firstly,the definition of few-shot learning is introduced. Then,the existing few-shot learning methods are divided into three categories,data enhancement,metric learning and meta-learning,which are analyzed and discussed in terms of the models used in the method,data sets and corresponding experimental results. Finally,the shortcomings of the existing methods are summarized,and the direction of future few-shot learning research is discussed.更多还原
