Goldfish is a suite of monolingual language models trained for 350 languages.
|
20 |
+
This model is the <b>Nigerian Pidgin</b> (Latin script) model trained on 24MB of data (all our data in the language), after accounting for an estimated byte premium of 0.95; content-matched text in Nigerian Pidgin takes on average 0.95x as many UTF-8 bytes to encode as English.
|
21 |
+
The Goldfish models are trained primarily for comparability across languages and for low-resource languages; Goldfish performance for high-resource languages is not designed to be comparable with modern large language models (LLMs).
|
22 |
+
|
23 |
+
Note: pcm_latn is an [individual language](https://iso639-3.sil.org/code_tables/639/data) code. It is not contained in any macrolanguage codes contained in Goldfish (for script latn).
|
24 |
+
|

+
All training and hyperparameter details are in our paper, [Goldfish: Monolingual Language Models for 350 Languages (Chang et al., 2024)](https://github.com/tylerachang/goldfish/blob/main/goldfish_paper_20240815.pdf).

+
|
33 |
+
To access all Goldfish model details programmatically, see https://github.com/tylerachang/goldfish/model_details.json.
|
34 |
+
All models are trained with a [CLS] (same as [BOS]) token prepended, and a [SEP] (same as [EOS]) token separating sequences.
