Yuzhe Gu

I am a second-year MS student pursuing dual degrees in Computer and Information Science and Electrical and Systems Engineering at the University of Pennsylvania, with a concentration on Artificial Intelligence and Machine Learning.

I received my dual Bachelor's degrees in Data Science from Duke Kunshan University and Duke University, where I worked closely with Enmao Diao and Peng Sun.

Research

My ongoing research interest focuses on improving algorithm efficiency and effectiveness in deep learning problems, particularly in the context of modern generative models for vision and language. Previously, I also worked on deep learning-driven audio processing, including applications in compression and speech synthesis.

ESC: Efficient Speech Coding with Cross-Scale Residual Vector Quantized Transformers


Yuzhe Gu, Enmao Diao
Conference on Empirical Methods in Natural Language Processing (EMNLP), 2024
paper / code /

We present ESC, a parameter-efficient speech foundation codec with cross-scale vector-quantized transformer architectures, which achieves coding performance comparable to state-of-the-art models while reducing decoding latency by 6.4x.

How Did We Get Here? Summarizing Conversation Dynamics


Yilun Hua, Nicholas Chernogor, Yuzhe Gu, Seoyeon Julie Jeong, Miranda Luo, Cristian Danescu-Niculescu-Mizil
Annual Conference of the North American Chapter of the Association for Computational Linguistics (NAACL), 2024
paper / code /

We introduce the task of summarizing the dynamics of conversations (SCD) by constructing a dataset of human-written summaries and exploring several automated baselines. We demonstrate that SCDs assist both humans and automated systems in forecasting whether an ongoing conversation will eventually derail into toxic behavior.

Towards Quantification of Covid-19 Intervention Policies from Machine Learning-based Time Series Forecasting Approaches


Yuzhe Gu, Peng Sun, Azzedine Boukerche
IEEE International Conference on Communications (ICC), 2024
paper /

We develop a policy-aware epidemic time-series predictive model, and perform causal analysis to quantify the effects of governmental interventions during COVID-19 through counterfactual estimation.

Robustness Evaluation on LLM Bias and Fairness Metrics


project: UPenn CIS700 - Trustworthy ML
2024/05
slides /

A re-evaluation on the robustness of text continuation-based bias metrics for quantifying group fairness in LLMs. Empirical results indicate that existing approaches are sensitive to language model’s inherent non-determinism from decoding setups.
