| Challenge: | Existing explanations for classifiers are counterfactual or contrastive . lack of universal ground truth for counterf actual edits hinders their evaluation . |
| Approach: | They propose a back translation-inspired evaluation methodology that utilises earlier outputs of the explainer as ground truth proxies to investigate the consistency of explainers. |
| Outcome: | The proposed method can provide valuable insights into the behaviour of predictor and explainer models and infer patterns that would otherwise be obscured. |
RISCORE: Enhancing In-Context Riddle Solving in Language Models through Context-Reconstructed Example Augmentation (2025.coling-main)

| Challenge: | Existing methods for prompting Large Language Models (LLMs) are lacking in advanced reasoning skills. |
| Approach: | They propose a method that generates and utilizes contextually reconstructed sentences to generate few-shot exemplars. |
| Outcome: | The proposed method significantly improves the performance of large language models in vertical and lateral thinking tasks, surpassing traditional exemplar selection strategies across a variety of few-shot settings. |
