# MemGen Annotations

This is the annotation dataset for the paper **[How Well Does Generative Recommendation Generalize?](https://huggingface.co/papers/2603.19809)**.

<a href="https://github.com/Jamesding000/MemGen-GR"><img src="https://img.shields.io/badge/Code-GitHub-green"></a>
<a href="https://huggingface.co/jamesding0302/memgen-checkpoints"><img src="https://img.shields.io/badge/Models-Hugging%20Face-blue"></a>

The annotations categorize evaluation instances under the leave-one-out protocol:
- **test** split uses the **last** item in the user history sequence as target,
- **val** split uses the **second-to-last** item as target.

## Columns
- `sample_id`: row index within the split in the original dataset.
- `user_id`: raw user identifier (join key).
- `master`: one of `memorization`, `generalization`, `uncategorized`.
- `subcategories`: list of `{rule, hop}` for fine-grained generalization types.
- `all_labels`: all string labels (e.g., `["generalization", "symmetry_3"]`).

## Load in M&G annotations
```python
from datasets import load_dataset

labels = load_dataset(
    "jamesding0302/memgen-annotations",
    "AmazonReviews2014-Beauty",
    split="test",
)
print(labels[0])
```

## Merge with processed dataset
```python
# 1) Load your processed dataset split (must be aligned with labels by row order)
ds = pipeline.split_datasets["test"]

# 2) Append label columns to the original dataset
ds = (ds
      .add_column("master", labels["master"])
      .add_column("subcategories", labels["subcategories"])
      .add_column("all_labels", labels["all_labels"]))
```
