讲座题目:Revolutionizing Anomaly Detection: Approaches and Guidelines

讲座摘要:

Anomaly detection plays a central role in data mining and remains a prominent subject of research in various areas of artificial intelligence. Its importance is underscored by its wide range of applications, including the identification of anomalous climatic events, mechanical malfunctions, potential threats, fraudulent activities, and malicious URLs. Dr Ye Zhu's presentation will provide a comprehensive overview of anomaly detection techniques, covering both shallow and deep learning-based methods, accompanied by in-depth explanations. Dr Zhu will explain the basic principles, objectives, underlying assumptions, and advantages and disadvantages of state-of-the-art anomaly detection approaches. He will also present several systematic approaches aimed at providing explanations for anomalies detected by deep learning models. In addition, Dr Zhu will explore the connections between conventional shallow methods and innovative deep techniques, and provide practical guidance on how to select the most appropriate outlier detection method for different scenarios.

讲座题目:Clustering massive datasets for pattern recognition

讲座摘要:

Clustering is a powerful technique for discovering patterns and hidden structures in data. However, many real-world datasets contain clusters with varied densities and irregular shapes, which pose challenges for traditional clustering algorithms. Kernel-based clustering is a technique designed to identify non-linearly separable clusters with irregular shapes, but they have high computational costs. In this talk, I will present some recent advances in kernel-based clustering that use an adaptive distributional kernel to overcome the limitations of existing clustering algorithms. These methods can achieve better clustering quality with lower computational cost than existing kernel-based algorithms and can handle large datasets efficiently. Their applications can range from image and speech processing to gene pattern extraction, community detection and market segmentation.
