+# MemoryCD
+
+A filtered cross-domain subset of the Amazon Reviews 2023 dataset, prepared
+for memory-augmented LLM evaluation on four recommendation tasks:
+rating prediction, sequential recommendation, explanation generation, and
+review generation.

+| Config | File | Records | Description |
+|---|---|---:|---|
+| `users_interactions` | `users/cross_domain_users_sampled.jsonl.gz` | 323 | Users with interactions 
+across all four domains below. Each record is a multi-line JSON object starting with `{"user_id": ...}` 
+containing an `interactions` dict keyed by domain. |
