Estimating Tail Risks in Language Model Output Distributions

ICML 2026spotlight

Language models are increasingly capable and are being rapidly deployed on a population-level scale. As a result, the safety of these models is increasingly high-stakes. Fortunately, advances in alignment have significantly reduced the likelihood of harmful model outputs. However, when models are qu…

A General Framework for Inference-time Scaling and Steering of Diffusion Models

ICML 2025poster

Diffusion models have demonstrated remarkable performance in generative modeling, but generating samples with specific desiderata remains challenging. Existing solutions --- such as fine-tuning, best-of-n sampling, and gradient-based guidance --- are expensive, inefficient, or limited in applicabil…

StyleDistance: Stronger Content-Independent Style Embeddings with Synthetic Parallel Examples

NAACL 2025long

Style representations aim to embed texts with similar writing styles closely and texts with different styles far apart, regardless of content. However, the contrastive triplets often used for training these representations may vary in both style and content, leading to potential content leakage in t…

Getting Serious about Humor: Crafting Humor Datasets with Unfunny Large Language Models

ACL 2024short

Humor is a fundamental facet of human cognition and interaction. Yet, despite recent advances in natural language processing, humor detection remains a challenging task that is complicated by the scarcity of datasets that pair humorous texts with similar non-humorous counterparts. We investigate whe…

ParaGuide: Guided Diffusion Paraphrasers for Plug-and-Play Textual Style Transfer

AAAI 2024technical

Textual style transfer is the task of transforming stylistic properties of text while preserving meaning. Target "styles" can be defined in numerous ways, ranging from single attributes (e.g. formality) to authorship (e.g. Shakespeare). Previous unsupervised style-transfer approaches generally rely…

TinyStyler: Efficient Few-Shot Text Style Transfer with Authorship Embeddings

EMNLP 2024finding

The goal of text style transfer is to transform the style of texts while preserving their original meaning, often with only a few examples of the target style. Existing style transfer methods generally rely on the few-shot capabilities of large language models or on complex controllable text generat…
