Revisiting Prompt Sensitivity in Large Language Models for Text Classification: The Role of Prompt Underspecification

Branislav Pecher, Michal Spiegel, Robert Belanec +1

Large language models (LLMs) are widely used as zero-shot and few-shot classifiers, where task behaviour is largely controlled through prompting. A growing number of works have obs…

Better as Generators Than Classifiers: Leveraging LLMs and Synthetic Data for Low-Resource Multilingual Classification

Branislav Pecher, Jan Cegin, Robert Belanec +3

Large Language Models (LLMs) have demonstrated remarkable multilingual capabilities, making them promising tools in both high- and low-resource languages. One particularly valuable…

PEFT-Bench: A Parameter-Efficient Fine-Tuning Methods Benchmark

Robert Belanec, Branislav Pecher, Ivan Srba +1

Despite the state-of-the-art performance of Large Language Models (LLMs) achieved on many tasks, their massive scale often leads to high computational and environmental costs, limi…

RoSE: Round-robin Synthetic Data Evaluation for Selecting LLM Generators without Human Test Sets

Jan Cegin, Branislav Pecher, Ivan Srba +1

LLMs are powerful generators of synthetic data, which are used for training smaller, specific models. This is especially valuable for low-resource languages, where human-labelled d…

Use Random Selection for Now: Investigation of Few-Shot Selection Strategies in LLM-based Text Augmentation for Classification

Jan Cegin, Branislav Pecher, Jakub Simko +3

The generative large language models (LLMs) are increasingly used for data augmentation tasks, where text samples are paraphrased (or generated anew) and then used for classifier f…

Fighting Randomness with Randomness: Mitigating Optimisation Instability of Fine-Tuning using Delayed Ensemble and Noisy Interpolation

Branislav Pecher, Jan Cegin, Robert Belanec +3

While fine-tuning of pre-trained language models generally helps to overcome the lack of labelled training samples, it also displays model performance instability. This instability…
