Keynote talk 1: Algorithmic fairness in link-based recommenders
Link-based recommender systems are a key feature of many of the online platforms we interact with every day. They recommend us people to connect with, as well as content and products to consume. We will begin by attempting to describe precisely what does it mean to discriminate in the context of recommendation: to produce disadvantageous differential treatment affecting members of some groups. Then, we will discuss how recommender systems might produce this of discrimination. In the final part, we will focus on link-based recommenders, as they might be strongly affected by groups that might be homophilic (i.e., having a strong tendency to link among them), which under various settings attract more recommendations at the expense of other groups. The talk will be based on the PhD work of David Solans and Francesco Fabbri.

Keynote talk 2: Towards algorithms for measuring and mitigating ML unfairness
It is increasingly evident that widely-deployed machine learning (ML) models can lead to discriminatory outcomes and exacerbate group disparities. The renewed interest in measuring and mitigating (un)fairness has led to various metrics and mitigation strategies. Nevertheless, the measurement problem remains challenging, as existing metrics may not capture tradeoffs relevant to the context at hand, and different fairness definitions can lead to incompatible outcomes. To this end, I will outline metric elicitation as a framework for addressing this metric selection problem — by efficiently estimating implicit preferences from stakeholders via interactive feedback. Towards mitigation, I will briefly outline emerging approaches for overlapping groups, unknown sensitive attributes, and other scenarios beyond the most widely studied settings.
