Database Search Results Disambiguation for Task-Oriented Dialog Systems
Kun Qian, Ahmad Beirami, Satwik Kottur +5
As task-oriented dialog systems are becoming increasingly popular in our lives, more realistic tasks have been proposed and explored. However, new practical challenges arise. For i…
Know Thy Strengths: Comprehensive Dialogue State Tracking Diagnostics
Hyundong Cho, Chinnadhurai Sankar, Christopher Lin +5
Recent works that revealed the vulnerability of dialogue state tracking (DST) models to distributional shifts have made holistic comparisons on robustness and qualitative analyses…
Information-Theoretic Bayes Risk Lower Bounds for Realizable Models
Matthew Nokleby, Ahmad Beirami
We derive information-theoretic lower bounds on the Bayes risk and generalization error of realizable machine learning models. In particular, we employ an analysis in which the rat…
Federated Learning with Heterogeneous Differential Privacy
Nasser Aldaghri, Hessam Mahdavifar, Ahmad Beirami
Federated learning (FL) takes a first step towards privacy-preserving machine learning by training models while keeping client data local. Models trained using FL may still leak pr…
Robustness through Data Augmentation Loss Consistency
Tianjian Huang, Shaunak Halbe, Chinnadhurai Sankar +5
While deep learning through empirical risk minimization (ERM) has succeeded at achieving human-level performance at a variety of complex tasks, ERM is not robust to distribution sh…
On Tilted Losses in Machine Learning: Theory and Applications
Tian Li, Ahmad Beirami, Maziar Sanjabi +1
Exponential tilting is a technique commonly used in fields such as statistics, probability, information theory, and optimization to create parametric distribution shifts. Despite i…
