The Role of Context and Uncertainty in Shallow Discourse Parsing

no code implementations COLING 2022 Katherine Atwell, Remi Choi, Junyi Jessy Li, Malihe Alikhani

We find that including annotator accuracy and confidence improves model accuracy, and incorporating confidence in the model’s temperature function can lead to models with significantly better-calibrated confidence measures.

Contextual ASR Error Handling with LLMs Augmentation for Goal-Oriented Conversational AI

no code implementations10 Jan 2025 Yuya Asano, Sabit Hassan, Paras Sharma, Anthony Sicilia, Katherine Atwell, Diane Litman, Malihe Alikhani

Evaluated in home improvement and cooking domains with real-world users, our method improves recall and F1 of correction by 34% and 16%, respectively, while maintaining precision and false positive rate.

Generating Signed Language Instructions in Large-Scale Dialogue Systems

no code implementations17 Oct 2024 Mert İnan, Katherine Atwell, Anthony Sicilia, Lorna Quandt, Malihe Alikhani

We introduce a goal-oriented conversational AI system enhanced with American Sign Language (ASL) instructions, presenting the first implementation of such a system on a worldwide multimodal conversational AI platform.

Studying and Mitigating Biases in Sign Language Understanding Models

no code implementations7 Oct 2024 Katherine Atwell, Danielle Bragg, Malihe Alikhani

Ensuring that the benefits of sign language technologies are distributed equitably among all community members is crucial.

APPDIA: A Discourse-aware Transformer-based Style Transfer Model for Offensive Social Media Conversations

1 code implementation COLING 2022 Katherine Atwell, Sabit Hassan, Malihe Alikhani

Then, we introduce the first discourse-aware style-transfer models that can effectively reduce offensiveness in Reddit text while preserving the meaning of the original text.

How people talk about each other: Modeling Generalized Intergroup Bias and Emotion

2 code implementations14 Sep 2022 Venkata S Govindarajan, Katherine Atwell, Barea Sinno, Malihe Alikhani, David I. Beaver, Junyi Jessy Li

Current studies of bias in NLP rely mainly on identifying (unwanted or negative) bias towards a specific demographic group.

PAC-Bayesian Domain Adaptation Bounds for Multiclass Learners

1 code implementation12 Jul 2022 Anthony Sicilia, Katherine Atwell, Malihe Alikhani, Seong Jae Hwang

Multiclass neural networks are a common tool in modern unsupervised domain adaptation, yet an appropriate theoretical description for their non-uniform sample complexity is lacking in the adaptation literature.

The Change that Matters in Discourse Parsing: Estimating the Impact of Domain Shift on Parser Error

4 code implementations Findings (ACL) 2022 Katherine Atwell, Anthony Sicilia, Seong Jae Hwang, Malihe Alikhani

Our results not only motivate our proposal and help us to understand its limitations, but also provide insight on the properties of discourse models and datasets which improve performance in domain adaptation.
