Study: Transformer Model Size Has Little Impact on Topic Coherence

A new study published on arXiv investigates the impact of transformer model size on topic coherence in Natural Language Processing. Researchers evaluated seven transformer-based language models, ranging from MiniLM to LLaMA-2, within a BERTopic pipeline. Their findings suggest that model size, from 22 million to 13 billion parameters, has a minimal effect on topic quality, indicating that smaller models can perform as well as larger ones. AI
