Learning Language and Multimodal Privacy-Preserving Markers of Mood from Mobile Data

no code implementations ACL 2021 Paul Pu Liang, Terrance Liu, Anna Cai, Michal Muszynski, Ryo Ishii, Nicholas Allen, Randy Auerbach, David Brent, Ruslan Salakhutdinov, Louis-Philippe Morency

Using computational models, we find that language and multimodal representations of mobile typed text (spanning typed characters, words, keystroke timings, and app usage) are predictive of daily mood.

Think Locally, Act Globally: Federated Learning with Local and Global Representations

4 code implementations6 Jan 2020 Paul Pu Liang, Terrance Liu, Liu Ziyin, Nicholas B. Allen, Randy P. Auerbach, David Brent, Ruslan Salakhutdinov, Louis-Philippe Morency

To this end, we propose a new federated learning algorithm that jointly learns compact local representations on each device and a global model across all devices.
