Rethinking Pivot Programming Languages in Code Language Models

Andor Diera, Lukas Galke Poech, Matthias Tichy

Multilingual code language models transfer skills across programming languages (PLs), but whether any PL occupies a privileged pivot position remains contested: geometric analyses…

Do Language Models Encode Semantic Relations? Probing and Sparse Feature Analysis

Andor Diera, Ansgar Scherp

Understanding whether large language models (LLMs) capture structured meaning requires examining how they represent concept relationships. In this work, we study three models of in…

Efficient Continual Learning for Small Language Models with a Discrete Key-Value Bottleneck

Andor Diera, Lukas Galke, Fabian Karl +1

Continual learning remains a challenge across various natural language processing (NLP) tasks, as models updated with new training data often risk catastrophic forgetting of previo…

Isotropy Matters: Soft-ZCA Whitening of Embeddings for Semantic Code Search

Andor Diera, Lukas Galke, Ansgar Scherp

Low isotropy in an embedding space impairs performance on tasks involving semantic inference. Our study investigates the impact of isotropy on semantic code search performance and…

Multi-View Structural Graph Summaries

Jonatan Frank, Andor Diera, David Richerby +1

A structural graph summary is a small graph representation that preserves structural information necessary for a given task. The summary is used instead of the original graph to co…
