arXiv:2605.14257v2 Announce Type: replace Abstract: We describe two types of models for vocabulary difficulty prediction: a high-accuracy black-box model, which achieved the top shared task result in the open track, and an explainable model, which outperforms a fine-tuned encoder baseline. As the black-box model, we fine-tuned an LLM using a soft-target loss function for effective application to the rating task, achieving r > 0.91. The explainable model provides insights into what impacts the difficulty of each item while maintaining a strong correlation (r > 0.77). We further analyze the resu
The proliferation of Large Language Models (LLMs) and the increasing need for interpretability in AI systems are driving research into understanding and improving their performance.
This work demonstrates advancements in both highly accurate and explicable AI models for a complex cognitive task, crucial for broader AI adoption and trust across various applications.
The ability to accurately predict and explain vocabulary difficulty signifies progress towards more capable and transparent AI, paving the way for adaptive learning systems and nuanced content generation.
