Jointly Attacking Graph Neural Network and its Explanations

arXiv.org Artificial Intelligence

Graph Neural Networks (GNNs) have boosted the performance for many graph-related tasks. Despite the great success, recent studies have shown that GNNs are highly vulnerable to adversarial attacks, where adversaries can mislead the GNNs' prediction by modifying graphs. On the other hand, the explanation of GNNs (GNNExplainer) provides a better understanding of a trained GNN model by generating a small subgraph and features that are most influential for its prediction. In this paper, we first perform empirical studies to validate that GNNExplainer can act as an inspection tool and have the potential to detect the adversarial perturbations for graphs. This finding motivates us to further initiate a new problem investigation: Whether a graph neural network and its explanations can be jointly attacked by modifying graphs with malicious desires? It is challenging to answer this question since the goals of adversarial attacks and bypassing the GNNExplainer essentially contradict each other. In this work, we give a confirmative answer to this question by proposing a novel attack framework (GEAttack), which can attack both a GNN model and its explanations by simultaneously exploiting their vulnerabilities. Extensive experiments on two explainers (GNNExplainer and PGExplainer) under various real-world datasets demonstrate the effectiveness of the proposed method.


Bridging the Gap between Spatial and Spectral Domains: A Unified Framework for Graph Neural Networks

arXiv.org Artificial Intelligence

Deep learning's performance has been extensively recognized recently. Graph neural networks (GNNs) are designed to deal with graph-structural data that classical deep learning does not easily manage. Since most GNNs were created using distinct theories, direct comparisons are impossible. Prior research has primarily concentrated on categorizing existing models, with little attention paid to their intrinsic connections. The purpose of this study is to establish a unified framework that integrates GNNs based on spectral graph and approximation theory. The framework incorporates a strong integration between spatial- and spectral-based GNNs while tightly associating approaches that exist within each respective domain.

Use Case: Detecting Defective Pills

#artificialintelligence

The manufacturing of products often requires careful quality control, especially when health and safety depend on the quality of the product. For example, in the case of medical pills, small physical defects may not only impact the appearance of the product, but can result in incorrect dosages. To help automate the detection of such defects, we set out to build an image recognition model in PerceptiLabs that could identify defective pills by analyzing images. A model like this could potentially help pharmaceutical companies, pharmacists, or medical practitioners identify physically defective pill products. To train our model, we used the images from the Pill defect dataset.

The surprising effectiveness of PPO in cooperative multi-agent games

AIHub

Recent years have demonstrated the potential of deep multi-agent reinforcement learning (MARL) to train groups of AI agents that can collaborate to solve complex tasks โ€“ for instance, AlphaStar achieved professional-level performance in the Starcraft II video game, and OpenAI Five defeated the world champion in Dota2. These successes, however, were powered by huge swaths of computational resources; tens of thousands of CPUs, hundreds of GPUs, and even TPUs were used to collect and train on a large volume of data. This has motivated the academic MARL community to develop MARL methods which train more efficiently. DeepMind's AlphaStar attained professional level performance in StarCraft II, but required enormous amounts of computational power to train. Research in developing more efficient and effective MARL algorithms has focused on off-policy methods โ€“ which store and re-use data for multiple policy updates โ€“ rather than on-policy algorithms, which use newly collected training data before each update to the agents' policies.
