In the first part we cover five current specific challenges through examples: (1) discrimination (e.g., facial recognition, justice, sharing economy, language models); (2) phrenology (e.g., biometric based predictions); (3) unfair digital commerce (e.g., exposure and popularity bias); (4) stupid models (e.g., Signal, minimal adversarial AI) and (5) indiscriminate use of computing resources (e.g., large language models). These examples do have a personal bias but set the context for the second part where we address four generic challenges: (1) too many principles (e.g., principles vs. techniques), (2) cultural differences; (3) regulation and (4) our cognitive biases. In the final part we discuss what we can do to address these challenges in the near future.<br><br>The second lecture covers two topics: the link prediction problem, and disparate effects of recommender systems. First, we will describe how link-level recommendation works considering both scoring-based methods and supervised learning-based methods, as well as describing evaluation methods for these recommenders. Second, we will study how recommender systems might have disparate effects. For instance, in the case of link-based recommenders, these disparate effects are evident if we consider groups that might be homophilic (i.e., having a strong tendency to link among them), as link-based recommender systems might generate more recommendations towards that group. We will cover various application scenarios for social media sites, from friend-recommendations to what-to-watch-next recommendations.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=gmail-m-4360065255461102783msonospacing style='margin:0in'><b><span lang=EN-US>REGISTRATION</span></b><span lang=EN-US>: Free of charge<o:p></o:p></span></p><p class=gmail-m-4360065255461102783msonospacing style='margin:0in'><span lang=EN-US> <o:p></o:p></span></p><p class=gmail-m-4360065255461102783msonospacing style='margin:0in'><b><span lang=EN-US>WHEN</span></b><span lang=EN-US>: March 10 (17:00 – 19:30).
