Instance test: SlimageNet64.

Accuracy is shown in %, as mean ± standard deviation across 5 random seeds. n-way = 1 for all experiments, to restrict distinguishing between similar instances of a single class. In the instance test, k-shot translates to the size of the support set. It is 1-shot in the sense that each instance is only shown once. NI, number of instances = 20 for all the experiments.准确率以百分比形式呈现，结果为5次随机种子实验下的均值±标准差。所有实验均采用N路分类（n-way）=1的设置，以限定模型仅区分同一类别下的相似样本。在实例测试中，k-shot指代支持集（support set）的规模；本次实验采用单样本（1-shot）设置，即每个实例仅被展示一次。所有实验的实例数量（number of instances，缩写为NI）均为20。
