Learning Universal Authorship Representations

1 code implementation EMNLP 2021 Rafael A. Rivera-Soto, Olivia Elizabeth Miano, Juanita Ordonez, Barry Y. Chen, Aleem Khan, Marcus Bishop, Nicholas Andrews

Determining whether two documents were composed by the same author, also known as authorship verification, has traditionally been tackled using statistical methods.

AnaloBench: Benchmarking the Identification of Abstract and Long-context Analogies

1 code implementation19 Feb 2024 Xiao Ye, Andrew Wang, Jacob Choi, Yining Lu, Shreya Sharma, Lingfeng Shen, Vijay Tiyyala, Nicholas Andrews, Daniel Khashabi

Our benchmarking approach focuses on aspects of this ability that are common among humans: (i) recalling related experiences from a large amount of information, and (ii) applying analogical reasoning to complex and lengthy scenarios.

Few-Shot Detection of Machine-Generated Text using Style Representations

1 code implementation12 Jan 2024 Rafael Rivera Soto, Kailin Koch, Aleem Khan, Barry Chen, Marcus Bishop, Nicholas Andrews

Furthermore, given a handful of examples composed by each of several specific language models of interest, our approach affords the ability to predict which model generated a given document.

Learning to Generate Text in Arbitrary Writing Styles

no code implementations28 Dec 2023 Aleem Khan, Andrew Wang, Sophia Hager, Nicholas Andrews

However, in applications such as writing assistants, it is desirable for language models to produce text in an author-specific style on the basis of a potentially small writing sample.

Can Authorship Attribution Models Distinguish Speakers in Speech Transcripts?

1 code implementation13 Nov 2023 Cristina Aggazzotti, Nicholas Andrews, Elizabeth Allyn Smith

Authorship verification is the task of determining if two distinct writing samples share the same author and is typically concerned with the attribution of written text.

Can Authorship Representation Learning Capture Stylistic Features?

1 code implementation22 Aug 2023 Andrew Wang, Cristina Aggazzotti, Rebecca Kotula, Rafael Rivera Soto, Marcus Bishop, Nicholas Andrews

Automatically disentangling an author's style from the content of their writing is a longstanding and possibly insurmountable problem in computational linguistics.

Low-Resource Authorship Style Transfer: Can Non-Famous Authors Be Imitated?

no code implementations18 Dec 2022 Ajay Patel, Nicholas Andrews, Chris Callison-Burch

Existing unsupervised approaches like STRAP have largely focused on style transfer to target authors with many examples of their writing style in books, speeches, or other published works.

In-Context Learning Style Transfer

Do Text-to-Text Multi-Task Learners Suffer from Task Conflict?

1 code implementation13 Dec 2022 David Mueller, Nicholas Andrews, Mark Dredze

Learning these models often requires specialized training algorithms that address task-conflict in the shared parameter updates, which otherwise can lead to negative transfer.

A Deep Metric Learning Approach to Account Linking

2 code implementations NAACL 2021 Aleem Khan, Elizabeth Fleming, Noah Schofield, Marcus Bishop, Nicholas Andrews

We consider the task of linking social media accounts that belong to the same author in an automated fashion on the basis of the content and metadata of their corresponding document streams.

Ensemble Distillation for Structured Prediction: Calibrated, Accurate, Fast-Choose Three

no code implementations EMNLP 2020 Steven Reich, David Mueller, Nicholas Andrews

However, extending these methods to structured prediction is not always straightforward or effective; furthermore, a held-out calibration set may not always be available.

Sources of Transfer in Multilingual Named Entity Recognition

1 code implementation ACL 2020 David Mueller, Nicholas Andrews, Mark Dredze

However, a straightforward implementation of this simple idea does not always work in practice: naive training of NER models using annotated data drawn from multiple languages consistently underperforms models trained on monolingual data alone, despite having access to more training data.

Learning Invariant Representations of Social Media Users

1 code implementation IJCNLP 2019 Nicholas Andrews, Marcus Bishop

The evolution of social media users' behavior over time complicates user-level comparison tasks such as verification, classification, clustering, and ranking.

Convolutions Are All You Need (For Classifying Character Sequences)

no code implementations WS 2018 Zach Wood-Doughty, Nicholas Andrews, Mark Dredze

While recurrent neural networks (RNNs) are widely used for text classification, they demonstrate poor performance and slow convergence when trained on long sequences.

Predicting Twitter User Demographics from Names Alone

1 code implementation WS 2018 Zach Wood-Doughty, Nicholas Andrews, Rebecca Marvin, Mark Dredze

Social media analysis frequently requires tools that can automatically infer demographics to contextualize trends.
