# stacked-xsum-1024 |
|
|
|
|
|
a "stacked" version of `xsum` |
|
|
|
1. Original Dataset: copy of the base dataset |
|
|
|
2. Stacked Rows: The original dataset is processed by stacking rows based on certain criteria: |
|
- Maximum Input Length: The maximum length for input sequences is 1024 tokens in the longt5 model tokenizer. |
|
- Maximum Output Length: The maximum length for output sequences is also 1024 tokens in the longt5 model tokenizer. |
|
|
|
3. Special Token: The dataset utilizes the `[NEXT_CONCEPT]` token to indicate a new topic **within** the same summary. It is recommended to explicitly add this special token to your model's tokenizer before training, ensuring that it is recognized and processed correctly during downstream usage. |
