\section{Attention Maps and Discovered Visual Representations}
We illustrate the attention maps and discovered instances of visual representations of all categories in VOC2012-10 and Travel in Fig.\ref{fig:buchongvoc} and Fig.\ref{fig:buchonglvyou1}, respectively. Two instances are shown for each category. The top row lists the original images, the middle row shows the attention maps after joint optimization, and the bottum row demonstrates the discovered instances of visual representation. Best viewed in color.

\section{Qualitative comparison}
We illustrate ten instances of visual representation discovered by six approaches from two categories in Travel, as shown in Fig.\ref{fig:lvyou3} and Fig.\ref{fig:lvyou4}, and two categories in VOC2012-10, as shown in Fig.\ref{fig:voc3} and Fig.\ref{fig:voc4}. The six approaches are (a) MDPM, (b) CBMS, (c) P-CNN, (d) PatternNet, (e) MFCN and (f) JDFR (ours), respectively.

\section{Instances of Visual Representation in CIFAR100-20}
The images in CIFAR100-20 have a low resolution $32\times32$. And, each image only contains one object that occupies the most space. Therefore, we only list four discovered instances of visual representation of a category in Fig.\ref{fig:cifar100}.
