Few-Shot Self-Rationalization with Natural Language Prompts

no code implementations Findings (NAACL) 2022 Ana Marasović, Iz Beltagy, Doug Downey, Matthew E. Peters

We identify the right prompting approach by extensively exploring natural language prompts on FEB. Then, by using this prompt and scaling the model size, we demonstrate that making progress on few-shot self-rationalization is possible.

Effective Attention Sheds Light On Interpretability

1 code implementation Findings (ACL) 2021 Kaiser Sun, Ana Marasović

An attention matrix of a transformer self-attention sublayer can provably be decomposed into two components and only one of them (effective attention) contributes to the model output.

Promoting Graph Awareness in Linearized Graph-to-Text Generation

no code implementations Findings (ACL) 2021 Alexander Hoyle, Ana Marasović, Noah Smith

Generating text from structured inputs, such as meaning representations or RDF triples, has often involved the use of specialized graph-encoding neural networks.

Denoising Text Generation

Explaining NLP Models via Minimal Contrastive Editing (MiCE)

1 code implementation Findings (ACL) 2021 Alexis Ross, Ana Marasović, Matthew E. Peters

Humans have been shown to give contrastive explanations, which explain why an observed event happened rather than some other counterfactual event (the contrast case).

Measuring Association Between Labels and Free-Text Rationales

1 code implementation EMNLP 2021 Sarah Wiegreffe, Ana Marasović, Noah A. Smith

In interpretable NLP, we require faithful rationales that reflect the model's decision-making process for an explained instance.

Formalizing Trust in Artificial Intelligence: Prerequisites, Causes and Goals of Human Trust in AI

no code implementations15 Oct 2020 Alon Jacovi, Ana Marasović, Tim Miller, Yoav Goldberg

We discuss a model of trust inspired by, but not identical to, sociology's interpersonal trust (i. e., trust between people).

Natural Language Rationales with Full-Stack Visual Reasoning: From Pixels to Semantic Frames to Commonsense Graphs

1 code implementation Findings of the Association for Computational Linguistics 2020 Ana Marasović, Chandra Bhagavatula, Jae Sung Park, Ronan Le Bras, Noah A. Smith, Yejin Choi

Natural language rationales could provide intuitive, higher-level explanations that are easily understandable by humans, complementing the more broadly studied lower-level explanations based on gradients or attention weights.

SRL4ORL: Improving Opinion Role Labeling using Multi-task Learning with Semantic Role Labeling

1 code implementation NAACL 2018 Ana Marasović, Anette Frank

For over a decade, machine learning has been used to extract opinion-holder-target structures from text to answer the question "Who expressed what kind of sentiment towards what?".

A Mention-Ranking Model for Abstract Anaphora Resolution

1 code implementation EMNLP 2017 Ana Marasović, Leo Born, Juri Opitz, Anette Frank

We found model variants that outperform the baselines for nominal anaphors, without training on individual anaphor data, but still lag behind for pronominal anaphors.

Multilingual Modal Sense Classification using a Convolutional Neural Network

no code implementations WS 2016 Ana Marasović, Anette Frank

Modal sense classification (MSC) is a special WSD task that depends on the meaning of the proposition in the modal's scope.
