Abstract: Machine learning techniques have found extensive applications in various domains although their security concerns have not been thoroughly explored and investigated. Many studies have shown that machine learning models can be easily misled by carefully crafted samples. This security issue becomes even more critical in the realm of deep learning, as publicly available datasets and pre-trained models are increasingly employed. Unfortunately, these datasets and models can be compromised by malicious third-party suppliers. This seminar aims to delve into the vulnerabilities of machine learning methods against adversarial attacks and explore strategies for enhancing their robustness.

New Research Directions in Evolutionary Multi-Objective Optimization

Abstract: In the field of evolutionary multi-objective optimization (EMO), various EMO algorithms have been proposed in the last three decades under the following widely-accepted implicit assumption: The final population is presented to the decision maker. Thus, the goal of EMO algorithm design is to find a good final population. The performance of EMO algorithms is evaluated using the final population. Recently, two different directions have been actively studied. One is the use of an unbounded external archive, and the other is the Pareto front (or Pareto set) modelling. In the first direction, all the examined solutions are stored in the archive. Then, an arbitrary number of solutions can be selected from the archive for the decision maker. In the second direction, the Pareto front (or Pareto set) is modelled by supervised learning based on examined non-dominated solutions or reinforcement learning based on a performance indicator. Then, an arbitrary number of final solutions can be obtained from the model for the decision maker. These two approaches are much more flexible than the traditional EMO algorithm framework since an arbitrary number of solutions can be presented to the decision maker, which may increase the practical usefulness of EMO-based decision making. In this talk, first I will explain the traditional EMO framework and the two new directions (the use of an unbounded external archive, and the modelling of the Pareto front/set). Then, I will discuss some interesting research challenges related to the two new directions such as subset selection from large candidate sets, use of examined solutions for generating new solutions, and the inverse mapping from the m-dimensional objective space to the n-dimensional decision space where n >> m.

Reproducibility Crisis of Artificial Intelligence in Practical Applications
Chao-Cheng Wu Chao-Cheng Wu
Associate Professor, National Taipei University of Technology, Taiwan

Abstract: The field of artificial intelligence has experienced remarkable growth in recent years. Technologies such as chatbots, generative AI, and image generators have been widely adopted across various industries, driving transformative advancements. However, the success rate of many practical applications of artificial intelligence (AI) and machine learning (ML) often falls short of expectations, with numerous AI or ML projects failing to progress to actual production.
Reproducibility is one of the major challenges encountered in practical applications of AI and ML. It refers to the ability to replicate an experiment and obtain the same results using the same methodology, a standard considered essential across all scientific disciplines. In the context of business applications, reproducibility helps establish systems that are less prone to errors and generally more reliable and predictable. This reliability is crucial for persuading decision-makers to scale AI systems and extend their benefits to a broader range of users. Unfortunately, as many AI practitioners are aware, issues with reproducibility are prevalent in many AI projects.
This presentation aims to share experiences from the implementation of AI in several practical applications, including medical, biological, and agricultural fields. In practical applications, data collection is the most critical step in implementing AI. Given that data collection is often labor-intensive and costly, datasets are generally small. Consequently, data leakage is a common issue that can adversely affect the reproducibility of AI. For instance, if plant disease data from the same field are divided between training and test sets, the AI model may learn to identify features associated with that specific field rather than the general patterns related to the disease. Moreover, the environment in which the data is collected also plays a significant role. In the aforementioned example, data collected from a single field may not accurately reflect real-world scenarios. In such cases, a method that produces reliable and valid results in a controlled environment may not be reproducible in more diverse, real-world settings. This issue is prevalent in many practical applications of AI, which is the focus of this presentation.

Abstract: Recently, there has been significant research on code intelligence using deep learning language models. In this talk, I will discuss how these techniques are integrated with programming languages to enhance code understanding and generation. I will start by introducing various tasks in code intelligence and then explore pretrained language models, such as CodeBERT and CodeT5, specifically designed to bridge the gap between programming and natural languages. Additionally, I will address the current challenges in this field. Key issues include managing the semantic discrepancies between different languages, ensuring the robustness of these models, and critically evaluating the functionality of the code they generate.
