A Comparative Study of PEFT Methods for Python Code Generation
(University of Tartu Library, 2025-03) Männistö, Johanna; Attieh, Joseph; Tiedemann, Jörg; Johansson, Richard; Stymne, Sara
Fine-tuning language models incurs high costs in training, inference and storage. Parameter-efficient fine-tuning (PEFT) methods have emerged as a more cost-effective alternative to full fine-tuning. However, limited work has compared different PEFT approaches for tasks like code generation. In this study, we examine the effect of various PEFT training methods on model performance in the task of Python code generation. We fine-tune four model families, ranging from 124M to 7B parameters, using three PEFT approaches alongside standard full fine-tuning. Our findings reveal that the effectiveness of each PEFT method varies with the model size and the corpus used.

Analyzing the Effect of Linguistic Instructions on Paraphrase Generation
(University of Tartu Library, 2025-03) Vahtola, Teemu; Hu, Songbo; Creutz, Mathias; Korhonen, Anna; Vulić, Ivan; Tiedemann, Jörg; Johansson, Richard; Stymne, Sara
Recent work has demonstrated that large language models can often generate fluent and linguistically correct text, adhering to given instructions. However, to what extent can they execute complex instructions requiring knowledge of fundamental linguistic concepts and elaborate semantic reasoning? Our study connects an established linguistic theory of paraphrasing with LLM-based practice to analyze which specific types of paraphrases LLMs can accurately produce and where they still struggle. To this end, we investigate a method of analyzing paraphrases generated by LLMs prompted with a comprehensive set of systematic linguistic instructions. We conduct a case study using GPT-4, which has shown strong performance across various language generation tasks, and we believe that other LLMs may face similar challenges in comparable scenarios. We examine GPT-4 from a linguistic perspective to explore its potential contributions to linguistic research regarding paraphrasing, systematically assessing how accurately the model generates paraphrases that adhere to specified transformation rules. Our results suggest that GPT-4 frequently prioritizes simple lexical or syntactic alternations, often disregarding the transformation guidelines if they overly complicate the primary task.
