解决的问题:主任务为有监督的out-of-distribution detection,于此同时要解决OOD detection问题,例子:在一个分类动物的问题上,要拒绝对一个人像进行识别,即不提供任何网络输出。
方法:一个两阶段的训练方法:
- 先训练一个C类分类器用于分类原始任务(即动物分类问题,C为动物类别)
- 再在已经训练后的分类器的最后一层添加新的K类分类层,用于做OOD detection,其中$K = C + A$,A为一个超参数,是OOD样本的总类别数(即假设OOD样本共有A个类别)。上述网络使用混合样本进行微调,其中混合样本是in- 和out- of distribution 样本的混合。OOD样本在训练的时候可以设置为任意的OOD(即,对于一个原始问题为猫狗分类的网络,OOD_train可以设置为人脸,即使在真实世界中的OOD样本不止有人脸)。上述训练方法的目标是:让网络能够在不忘记in-distribution样本特征的情况下,还能记住OOD的一部分特征。
- 在推理的时候,使用步骤2的分类层,即K类的分类层。对于任意一个测试样本,首先计算在C类分类问题上的预测结果,即$y_{pred} = arg_{max_i}{\gamma[1:C]}$,让后计算其OOD score,$Score_{OOD} = sum(\gamma[C:K])$,即在A类OOD分类上的SOFTMAX响应总和。
- 个人理解:OOD样本将在C:K上有较高的响应,此时该样本的$y_{pred}$将不可信,并拒绝该样本的分类。反之则接受该样本的分类。

Data augmentation
Random Erasing Data Augmentation
Zhun Zhong (Xiamen University)*; Liang Zheng (Australian National University); Guoliang Kang (CMU); Shaozi Li
(Xiamen University, China); Yi Yang (UTS)论文为CNN训练提出了一种新的数据增强方法。Random Erasing,在一张图片中随机的选择一个矩形框,在随机的位置上使用随机的值来擦除图片原来的像素。通过该方法能够给图片加入不同程度的遮挡,通过这样的训练数据,可以减少模型过拟合的风险同时对遮挡具有一定的鲁棒性。随机擦除和random cropping,random flipping一样可以作为数据增强的方法,在分类,检测和行人重识别领域能够取得不错的效果。

CONAN: Complementary Pattern Augmentation for Rare Disease Detection
Limeng Cui (Penn State University); Siddharth Biswal (Georgia Institute of Technology); Lucas Glass (IQVIA); Greg
Lever (IQVIA); Jimeng Sun (Georgia Tech); Cao Xiao (IQVIA)*稀有疾病影响着全世界亿万人民,但由于它们的患病率极低(从1 / 1,000到1 / 200,000患者不等)并且被严重误诊,因此难以发现。我们如何可靠地检测出如此低的患病率?如何进一步利用诊断可能不确定的患者改善检测率?在本文中,我们提出了一种用于罕见病检测的互补模式增强(CONAN)框架。CONAN结合了对抗训练和最大利润率分类的思想。它首先学习自我专注和分层嵌入,以进行患者模式表征。然后,我们开发了互补的生成对抗网络(GAN)模型,通过鼓励各类别之间的最大差额来生成不确定患者的候选阳性和阴性样本。此外,CONAN具有疾病检测器,可在对抗性训练期间用作识别罕见疾病的识别器。我们在两项疾病检测任务上评估了CONAN。对于低流行性炎症性肠病(IBD)检测,CONAN曲线下的精确召回面积(PR-AUC)为0.96,相对于最佳基线,相对改善了50.1%。对于罕见疾病特发性肺纤维化(IPF)检测,CONAN达到0.22 PR-AUC,相对最佳基准,相对改善41.3%。

Incorporating Label Embedding and Feature Augmentation for Multi-Dimensional Classification
Haobo Wang (Zhejiang University)*; Chen Chen (Zhejiang University); Weiwei Liu (Wuhan University); Ke Chen (
Zhejiang University); Tianlei Hu (Zhejiang University); Gang Chen (Zhejiang University)通过集成标签信息来操纵特征空间的特征增强是解决多维分类(MDC)问题的最流行策略之一。但是,香草特征增强方法无法考虑类内的排他性,并且可能会导致性能下降。为了填补这一空白,提出了一种基于神经网络的新型模型,该模型将标签嵌入和特征增强(LEFA)技术无缝集成以学习标签相关性。具体地,基于注意力分解机,引入了互相关感知网络以学习低维标签表示,其同时描绘了类间相关性和类内排他性。然后,可以将学习到的潜在标签矢量用于扩大原始特征空间。
