Finetuning / P-Tuning
We have been reported to have issues(https://github.com/kakaobrain/kogpt/issues/17) with our downstream evaluation.
The previously published performance evaluation table was deleted because it was difficult to see it as a fair comparison because the comparison target algorithm was different and the performance measurement method could not be confirmed.
You can refer to the above issue link for the existing performance evaluation table and troubleshooting results.
Limitations
KakaoBrain KoGPT
was trained on rayn dataset
, a dataset known to contain profanity, lewd, political changed, and other harsh language.
Therefore, KoGPT
can generate socially unacceptable texts. As with all language models, It is difficult to predict in advance how KoGPT
will response to particular prompts and offensive content without warning.
Primarily Korean: KoGPT
is primarily trained on Korean texts, and is best for classifying, searching, summarizing or generating such texts.
KoGPT
by default perform worse on inputs that are different from the data distribution it is trained on, including non-Korean as well as specific dialects of Korean that are not well represented in the training data.
