Algorithmic Fidelity of Large Language Models in Generating Synthetic German Public Opinions: A Case Study

ACL 2025long

In recent research, large language models (LLMs) have been increasingly used to investigate public opinions. This study investigates the algorithmic fidelity of LLMs, i.e., the ability to replicate the socio-cultural context and nuanced opinions of human participants. Using open-ended survey data fr…

Adaptive Contrastive Search: Uncertainty-Guided Decoding for Open-Ended Text Generation

EMNLP 2024finding

Despite the remarkable capabilities of large language models, generating high-quality text remains a challenging task. Numerous decoding strategies—such as beam search, sampling with temperature, top‐k sampling, nucleus (top‐p) sampling, typical decoding, contrastive decoding, and contrastive search…

Divergent Token Metrics: Measuring degradation to prune away LLM components – and optimize quantization

NAACL 2024long

Large Language Models (LLMs) have reshaped natural language processing with their impressive capabilities. However, their ever-increasing size has raised concerns about their effective deployment and the need for LLM compression. This study introduces the Divergent Token Metrics (DTMs), a novel appr…

Automatic Transcription of Handwritten Old Occitan Language

EMNLP 2023long main

While existing neural network-based approaches have shown promising results in Handwritten Text Recognition (HTR) for high-resource languages and standardized/machine-written text, their application to low-resource languages often presents challenges, resulting in reduced effectiveness. In this pape…

Evaluating Unsupervised Representation Learning for Detecting Stances of Fake News

COLING 2020main

Our goal is to evaluate the usefulness of unsupervised representation learning techniques for detecting stances of Fake News. Therefore we examine several pre-trained language models with respect to their performance on two Fake News related data sets, both consisting of instances with a headline, a…
