Evaluating Cost-Efficiency of LLMs in a RAG Setup on Polish Wikipedia: Quality vs. Energy Consumption (2026.eacl-srw)
Copied to clipboard
| Challenge: | Retrieval-augmented generation systems are a dominant paradigm for knowledge-intensive applications. |
| Approach: | They evaluate language models from 4B to 70B parameters within a Polish Wikipedia-based RAG pipeline. |
| Outcome: | The proposed model selection process reduces energy consumption by 83% and improves quality. |
Comprehensive Punctuation Restoration for English and Polish (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Punctuation restoration is a fundamental requirement for the readability of text derived from Automatic Speech Recognition systems. |
| Approach: | They evaluate several methods in the comprehensive punctuation reconstruction task by comparing two languages with a model to determine the quality of the punctuated word. |
| Outcome: | The proposed model improves on two languages with relatively simple and complex morphologies. |
