roberta-base-wechsel-ukrainian
roberta-base transferred to Ukrainian using the method from the NAACL2022 paper WECHSEL: Effective initialization of subword embeddings for cross-lingual transfer of monolingual language models.
Evaluation
Evaluation was done on lang-uk's ner-uk project, the Ukrainian portion of WikiANN and the Ukrainian IU corpus from the Universal Dependencies project. Evaluation results are the mean of 5 runs with different seeds.
