The 52k Alpaca set, generated by Text-Davinci-003, includes many responses that are wrong or off-topic. Such examples can mislead the fine-tuned model and make training cost more. Earlier cleanup efforts like Alpaca-cleaned… 2. **[IMRNNs: An Efficient Method for Interpretable Dense Retrieval via Embedding Modulation](https://md.research.elamur.ai/free/en/papers/saxena-2026-imrnns-efficient-method-interpretable-dense/)** *(2026)* Dense retrievers in RAG pipelines encode queries and documents into fixed vectors on their own. As a result, a document's representation cannot change depending on the query, and users cannot see why a document was ranked highly. The authors present IMRNNs, a lightweight add-on that works over a frozen encoder.… 3. **[Switching Heads and Softening Tokens: Turnkey Solutions to Visually Grounded Document QA](https://md.research.elamur.ai/free/en/papers/wen-2026-switching-heads-softening-tokens-turnkey/)** *(2026)* The paper tackles visually grounded document question answering (VGDQA), where a model must answer a question about a document and also mark where each answer sits on the page. ## All works 4 works of theirs in our library, the most cited first; 3 with a page here, the others link their original until we summarise them. 1.
