Hidden nonlinear patterns in the dataset can further complicate the multi-class categorisation (Gao et al., 2021). In Simoncini et al. (2018), the unbalanced data problem was addressed by investigating the efficiency of advanced NN designs for vehicle multi-class classification by using low-...

当有一个待测试的样本加入时,我们把它放到dataset中,进行K近邻的聚类。通过某种距离测量的衡量指标,...
I have a dataset of 3 classesanimals,landscapes, andbuildings. It is only a 100 images per dataset and I am trying to train a classifier using ResNet34 + fastai but I'm running into several issues. The first one is that I don't think my model is training properly. When I use the...

Zero-shot classification and detection 简单说一下Zero-shot,就是预测一个在训练集样本中不存在的label,比如用猫和狗数据集训练出来一个能识别出猫、狗、兔子的模型。 Zero-shot的起因:[1,8]。通常通过通过语义嵌入[25]或辅助属性注释[7]来表示一个新的类来实现。
