Research Experience Research Assistant March 2019 – May 2021 Department of Computer Science, University of Rochester Rochester, NY – Jointly advised by Professor Henry Kautz, Professor Ehsan Hoque, and Doctor Vincent Silenzio. – Developed ubiquitous computing frameworks for personalized mental disorder sensing through longitudinal private Google Search and YouTube data. – Extended the above frameworks for COVID-19 and found significant correlations between deteriorating mental health profiles and online behavior shifts during the pandemic (r ranging between 0:47 and 0:75, p ≤ :03). – Simulated the semantics and stochasticity of user online engagements with mutually exciting Hawkes Processes to detect major depressive disorder (F1: 0:77 ± 0:04, AUROC: 0:81 ± 0:02). – Extracted interpretable semantic and temporal features, including novel representations for content entropy and interevent times, from personal online data; customized a Gaussian Process to continuously predict generalized anxiety disorder (MSE: 1:87 ± 0:14). – Designed a Bayesian graphical model with MCMC methods that leverages the latent information of self-esteem and online activities to identify past suicidal ideation (F1: 0:82, AUROC: 0:79). – Collaborated with the URMC and recruited more than 200 volunteers; periodically collected clinically validated mental health evaluation results and individual online activity logs from the study cohort. Research Assistant October 2019 – December 2020 Department of Computer Science, University of Rochester Rochester, NY – Advised by Professor Daniel Štefankovič. – In a group of 2, completed theoretical proofs of the generalization error bounds for several diversity and weight-based pruning methods on feed-forward neural networks under a statistical mechanics framework. – Proposed a novel diversity-based edge pruning algorithm based on Determinantal Point Process; improved network compression performances from previous diversity-based methods on both synthetic and real-world datasets. Research Assistant February 2019 – August 2019 Department of Linguistics, University of Rochester Rochester, NY Page 2 of 3 – Advised by Professor Aaron Steven White at the Formal and Computational Semantics Lab. – Implemented three deep graph encoders over WordNet for word sense embedding: a child-sum graph bi-LSTM, a matrix decomposition method with graph kernels, and a Graph Convolutional Networks. – Developed a sequence-to-sequence model with von Mises-Fisher loss for word sense disambiguation (WSD); improved the model to work on unknown words by incorporating the Supersense relations from WordNet. The best model achieved 75% accuracy on the Universal Decompositional Semantics Word Sense dataset.
