“…The Basic ideas of each few-shot learning are shown in Table 1. At present, with the continuous development and optimization in few-shot learning, a large quantity of application cases of few-shot learning have emerged in many industries, such as remote sensing computer vision (Sun et al 2021;Guo, Wang et al 2022), intelligent agriculture Nie, Wang et al 2022a;), biomedicine (Yin et al 2020), plant protection Li & Chao, 2021b), magnetic field physical and chemical parameter prediction (Nie et al 2021;Nie et al 2022), geological exploration (Liu et al 2022), radar ranging (Yue Yang et al 2021), point cloud segmentation (Guo et al 2020), etc. This article will outline and respond to the research questions below: 1) How is the present state of studies about few-shot learning?…”
