-------------
+Graph robustness is an important research direction in the field of graph representation learning in recent years, 
+and we have integrated graph robustness-related algorithms in AutoGL, which can be easily used in conjunction with other modules.

+Preliminaries
+-----------
+In AutoGL, we divide the algorithms for graph robustness into three categories, which are placed in different modules for implementation.
+Robust graph feature engineering aims to generate robust graph features in the data pre-processing phase to enhance the robustness of downstream tasks.
+Robust graph neural networks, on the other hand, are designed at the model level to ensure the robustness of the model during the training process.
+Robust graph neural network architecture search aims to search for a robust graph neural network architecture.
+Each of these three types of graph robustness algorithms will be described in the following sections.

-    cd DeepRobust
-    python setup.py install
+We provide structure engineering methods to enhance robustness, please refer to `preprocessing` part for more information.
 
-To better plugin GNNGuard to AutoGL, we slightly revised some functions in geometric. Please use the file ``AutoGL/autogl/module/model/pyg/robust/nn/conv/gcn_conv.py`` we provided to replace the corresponding file in the installed geometric folder (for example, the folder path could be `/home/username/.local/lib/python3.5/site-packages/torch_geometric/nn/conv/`).

+图鲁棒性
+============================
+
+图鲁棒性是近年图机器学习领域重要的研究方向，我们在AutoGL中集成了图鲁棒性相关算法，可以方便地与其他模块结合使用。

+背景知识
+------------
+
+（介绍对抗攻击、鲁棒问题的定义等，可以适当引一些paper）
+
+在AutoGL中，我们将图鲁棒性的算法分为三类，放在不同的模块中实现。
+鲁棒图特征工程旨在数据预处理阶段生成鲁棒的图特征，增强下游任务的鲁棒性。
+鲁棒图神经网络则是通过模型层面的设计，以在训练过程中确保模型的鲁棒性。
+鲁棒图神经网络架构搜索旨在搜索出一个鲁棒的图神经网络架构。
+下文中将分别介绍这三类图鲁棒性算法。
