# checkpoints |
|
|
|
- This model is a fine-tuned version of [google/t5-v1_1-base](https://huggingface.co/google/t5-v1_1-base) on the `vblagoje/lfqa` dataset, with training duration of 2 epochs, for a (_somewhat_) apples-to-apples comparison with [t5-base](https://huggingface.co/pszemraj/t5-base-askscience) on the standard eli5 dataset. |
|
- This checkpoint does seem to be more coherent than t5-base on the original dataset. |
|
- Compared to [bart on lfqa](https://huggingface.co/vblagoje/bart_lfqa), it seems to be able to respond to some questions independently of retrieval. |
|
|
|
> NOTE: the inference API is limited to generating approx. 64 chars for runtime reasons, for longer outputs try using it in python as a transformers pipeline object. |
|
|
|
## Intended uses & limitations |
|
|
|
- Q&A, information retrieval |
|
- it is probably better to use it with a [retrieval pipeline](https://github.com/deepset-ai/haystack) than alone |
|
|
|
## Training and evaluation data |
|
|
|
- see linked dataset. the dataset was filtered to only included the `askscience` subreddit in an attempt to focus on academic/technical queries. |
|
|
|
