Valid hypothesis testing after hierarchical clustering

November 6, 2020 @ 11:00 am - 12:00 pm

Daniela Witten (University of Washington)

online

Abstract:  As datasets continue to grow in size, in many settings the focus of data collection has shifted away from testing pre-specified hypotheses, and towards hypothesis generation. Researchers are often interested in performing an exploratory data analysis in order to generate hypotheses, and then testing those hypotheses on the same data; I will refer to this as ‘double dipping’. Unfortunately, double dipping can lead to highly-inflated Type 1 errors. In this talk, I will consider the special case of hierarchical…

Antitrust in the Digital Era – Platforms

November 5, 2020 @ 4:00 pm - 6:00 pm

Dr. Alexandra von Westernhagen

Online

Access via Zoom: https://mit.zoom.us/j/3980544883 There is no denial that antitrust policy is at a crossroads. The emergence of online platforms as quasi-monopolies with wide reach into vertically integrated markets, the strategic importance of data to gain competitive advantages as well  as mergers and acquisitions in the digital field have led to a re-think about the application of antirust rules in the US, Europe and other jurisdictions around the world. More recently issues related to the content of information under Rule…

Personalized Federated Learning: A Model-Agnostic Meta-Learning Approach

November 4, 2020 @ 4:00 pm - 4:30 pm

Alireza Fallah (LIDS)

Online

ABSTRACT In Federated Learning, we aim to train models across multiple computing units (users), while users can only communicate with a common central server, without exchanging their data samples. This mechanism exploits the computational power of all users and allows users to obtain a richer model as their models are trained over a larger set of data points. However, this scheme only develops a common output for all the users, and, therefore, it does not adopt the model to each…

Regulating Algorithmic Filtering on Social Media

October 28, 2020 @ 4:00 pm - 4:30 pm

Sarah Cen (LIDS)

Online

ABSTRACT Social media platforms moderate content using a process known as algorithmic filtering (AF). While AF has the potential to greatly improve the user experience, it has also drawn intense scrutiny for its roles in, for example, spreading fake news, amplifying hate speech, and facilitating digital red-lining. However, regulating AF can be harmful to the social media ecosystem by interfering with personalization, lowering profits, and restricting free speech. We are interested in whether or not it is possible to design…
