Amazon recommendation tools

Frozen catalog artifacts and behavior-trained recommendation tools used by RecoAtlas. This is an inference-artifact repository, not a standalone Transformers model and not a record of training runs.

Each category contains exactly the files needed by the released tools:

<category>/
  data/product_texts.json
  data/subcategories.json
  embeddings/item_embeddings_qwen.pt
  embeddings/complementarity_embeddings_qwen.pt
  models/retrieval_model_qwen.pt
  manifest.json

• retrieval_model_qwen.pt is the selected query-side LoRA retrieval checkpoint.
• item_embeddings_qwen.pt contains the frozen catalog item vectors used by semantic search and near-duplicate pruning.
• complementarity_embeddings_qwen.pt contains the selected catalog-aligned anchor_embs and complement_embs used by the utility-aligned complementarity tool. It is the complementarity inference artifact; historical epoch checkpoints and training runs are intentionally omitted.
• manifest.json records exact sizes and SHA-256 checksums.

The underlying query/reference benchmark is iaouali/amazon-benchmark. The base query encoder is Qwen/Qwen3-Embedding-0.6B. Catalog content, source datasets, and the base model remain subject to their respective terms. See NOTICE.
