Title: Preventive Cybersecurity as a Social Responsibility: The Bright Origin Approach

Abstract: The cybercrimes and fakes on the Internet are so prolific that the cybersecurity has been the top concern to CIOs during last ten years consecutively according to the study of Society of Information Management (SIM). Since the complete protection of individual organization’s cybersecurity is nearly impossible to fulfill without the collective effort of mitigating the threat sources, we paid attention to the preventive cybersecurity paradigm and designed the Bright Internet Architecture with the Principle of Origin Responsibility.

To validate the Bright Origin approach with the perspective of organization’s Social Responsibility, we identify the eight threat types and ten critical platforms that would create social damages beyond the organizational boundary. To measure the needs of preventive action on these risk sources, we survey the opinions of CIOs and IT experts who would understand the social responsibility aspect of cybersecurity for the future. According to this study, we found that they regard the preventive actions with social responsibility will mitigate the risk sources and will eventually contribute to building the safer environment for individual organizations.  To motivate the efforts to realize the preventive actions, the direct benefits can be obtained by endowing the Certificate of Bright Origins that will create reputation from the customers and social community.

Title: Understanding and Addressing Bias and Privacy Challenges in Large Language Models

Abstract: Large language models have reshaped the AI landscape, yet they cast shadows of bias and privacy concerns that demand our attention. This research talk investigates the technical roots of these issues, tracing them to biased training data and algorithmic limitations, while exploring privacy vulnerabilities stemming from model architecture, fine-tuning, and data leakage. We navigate the terrain of bias mitigation techniques, such as debiasing data and fairness-aware algorithms, and privacy-preserving methods like federated learning and differential privacy. Furthermore, we scrutinize the legal dimension, contemplating the applicability of existing regulations, AI-specific legislation, consent mechanisms, and accountability frameworks. Ethical dilemmas at the intersection of bias and privacy are discussed, highlighting trade-offs and synergies, while also envisioning a future where interdisciplinary research, industry self-regulation, and user education forge responsible AI practices that promote fairness and protect user privacy. This talk equips researchers, developers, and policymakers with a comprehensive understanding of these multifaceted challenges and the strategies to address them in large language models.

Title: Content Sharing When Customers Can Multihome

Abstract: In this study, we investigate the strategic decisions made by platforms regarding the sharing of exclusive content with competitors, a puzzle that has sparked considerable debate due to the observed disparity in sharing strategies across industries. For example, sharing strategy is prevalent in certain industries, e.g., video gaming, but is almost nonexistent in some other ostensibly similar industries, e.g., video streaming. Surprisingly, we identify the ratio of multihoming consumers - a factor previously overlooked - as a potential key determinant of these strategic differences. Our analysis reveals that when the ratio of multihoming consumers is low, sharing content to the competing platform leads to a win-win situation for the two platforms. Whereas when the ratio is high, sharing will not benefit both platforms. This intriguing phenomenon is primarily driven by the differing ways of valuation employed by singlehoming and multihoming consumers towards platform content. This study thus establishes a connection between customer heterogeneity in terms of platform usage and the state of content sharing among competing firms. Furthermore, we demonstrate that content sharing can lead to higher consumer surplus, highlighting the societal benefits of wide content distribution. This interesting finding has significant managerial and policy implications, which we discuss accordingly. Our study offers a fresh perspective on content sharing strategies, underscoring the pivotal role of multihoming consumers.

Title: When More is Less: The Other Side of Artificial Intelligence Recommendation

Abstract: Based on consumers' preferences, AI (artificial intelligence) recommendation automatically filters information, which provokes scholars' debate. Supporters believe that by analyzing the consumers' preferences, AI recommendation enables consumers to choose products more quickly and with lower cost. Critics deem that consumers are more easily trapped in information cocoons because of the use of AI recommendation. This reduces the possibility of consumers contacting with a variety of commodities, thus lowering the consumer decision quality. Based on experiments, this paper discusses the moderating role of AI recommendation on the relationship of consumers' preferences and information cocoons. Moreover, it examines the relationship between information cocoons and consumer decision quality. The findings are: AI recommendation strengthens consumers' preferences; consumers' preferences are positively correlated with information cocoons and further leads to the decline of consumers’ decision quality. In the AI era, this paper contributes to revealing the dark sides of AI recommendation and provides empirical evidence for the regulation of AI behaviors.

Title: Novel Formulations and Logic-Based Benders Decomposition for the Integrated Parallel Machine Scheduling and Location Problem

Abstract: We investigate the discrete parallel machine scheduling and location (ScheLoc) problem, which consists of locating multiple machines to a set of candidate locations, assigning jobs from different locations to the located machines, and sequencing the assigned jobs. The objective is to minimize the maximum completion time of all jobs, i.e., the makespan. Though the problem is of theoretical significance with a wide range of practical applications, it has not been well studied as reported in the literature. For this problem, we first propose three new mixed-integer linear programs (MILPs) that outperform state-of-the-art formulations. Then, we develop a new logic-based Benders decomposition algorithm for practical-sized instances, which splits the problem into a master problem that determines machine locations and job assignments to machines, and a subproblem that sequences jobs on each machine. The master problem is solved by a branch-and-cut procedure that operates on a single search tree. Once an incumbent solution to the master problem is found, the subproblem is solved to generate cuts that are dynamically added to the master problem. A generic no-good cut is first proposed, which is later improved by some strengthening techniques. Two optimality cuts are also developed based on optimality conditions of the subproblem, and improved by strengthening techniques. Numerical results on small-sized instances show that the proposed formulations outperform state-of-the-art ones. Computational results on 1400 benchmark instances with up to 300 jobs, 60 machines, and 300 locations demonstrate the effectiveness and efficiency of the algorithm compared to current approaches.

Title：Efficient Nonparametric Inference for Conditional Expectile Functions with Large-Scale Time Series Data

Abstract: Expectile is a coherent and elicitable law-invariant risk measure and it has been widely applied in actuarial and financial risk management. This paper focuses on developing efficient estimation and inference for nonparametric conditional expectile functions of large-scale time series data. Most existing methods based on iteratively reweighted least squares (IWLS) algorithms are not computationally feasible for nonparametric expectile estimation and inference when the sample size is big. To overcome the issue, we develop a direct nonparametric method by inverting the local polynomial estimator of the conditional loss-gain function, to estimate conditional expectile functions for time series. The proposed estimator is computationally stable with no resort to any iterative algorithms. Moreover, the proposed estimator is statistically more efficient than the existing IWLS based methods. We establish the asymptotic distributions of the proposed estimator for statistical inference of the conditional expectile functions.  Monte Carlo simulations show that the proposed method is computationally efficient and has the desired finite sample performance which outperforms the expectile-loss-based method in terms of mean squared errors. We further illustrate the proposed methods using the S&P500 data set by evaluating the computational time for estimating the conditional expectile-based value-at-risk (EVaR) of S&P500 returns, and the accuracy in predicting EVaR for the out-of-sample observations.
