Erasing More Than Intended? How Concept Erasure Degrades the Generation of Non-Target Concepts

ICCV 2025poster

Concept erasure techniques have recently gained significant attention for their potential to remove unwanted concepts from text-to-image models. While these methods often demonstrate promising results in controlled settings, their robustness in real-world applications and suitability for deployment…

Opportunities for Human-centered Evaluation of Machine Translation Systems

NAACL 2022findings

Machine translation models are embedded in larger user-facing systems. Although model evaluation has matured, evaluation at the systems level is still lacking. We review literature from both the translation studies and HCI communities about who uses machine translation and for what purposes. We emph…

Efficient and Scalable Bayesian Neural Nets with Rank-1 Factors

ICML 2020poster

Bayesian neural networks (BNNs) demonstrate promising success in improving the robustness and uncertainty quantification of modern deep learning. However, they generally struggle with underfitting at scale and parameter efficiency. On the other hand, deep ensembles have emerged as alternatives for u…

Learning to Detect Sepsis with a Multitask Gaussian Process RNN Classifier

ICML 2017poster

We present a scalable end-to-end classifier that uses streaming physiological and medication data to accurately predict the onset of sepsis, a life-threatening complication from infections that has high mortality and morbidity. Our proposed framework models the multivariate trajectories of continuou…

The Bayesian Echo Chamber: Modeling Social Influence via Linguistic Accommodation

AISTATS 2015poster

We present the Bayesian Echo Chamber, a new Bayesian generative model for social interaction data. By modeling the evolution of people’s language usage over time, this model discovers latent influence relationships between them. Unlike previous work on inferring influence, which has primarily focuse…
