Indonesian BERT2BERT Summarization Model

Finetuned EncoderDecoder model using BERT-base and GPT2-small for Indonesian text summarization.

Finetuning Corpus

bert2gpt-indonesian-summarization model is based on cahya/bert-base-indonesian-1.5G and cahya/gpt2-small-indonesian-522Mby cahya, finetuned using id_liputan6 dataset.
