Abstract:With the development of large-scale datasets, deep learning-based neural network models have achieved excellent results in image recognition fields such as face recognition, intelligent driving, and medical diagnosis. However, in practical applications, due to various limiting factors, researchers are unable to obtain a large number of samples that meet the requirements. Therefore, studying image recognition under small sample conditions is very meaningful. This work systematically reviews recent research progress in few-shot learning in the field of image recognition, introducing and analyzing related work from three aspects: data augmentation-based methods, representation learning-based methods, and learning strategy-based methods. Based on the current research situation, it also explores and discusses future research directions.
