Hugging Face 發表技術部落格，介紹如何使用 `EncoderDecoderModel` 將現有的預訓練編碼器（如 BERT）與解碼器（如 GPT-2）結合。 這種「熱啟動（Warm-starting）」方法免去了從頭訓練 Seq2Seq 模型的巨大成本，特別適合摘要生成和機器翻譯等任務。 文章詳細說明了架構原理、交叉注意力機制的初始化，並提供了實用的 Transformers 程式碼範例。
In the field of natural language processing (NLP), sequence-to-sequence (Seq2Seq) models — such as those used for translation or summarization — typically require enormous computational resources and data to train from scratch. In this technical blog post, Hugging Face introduces an efficient alternative called "warm-starting," which allows developers to directly leverage existing pre-trained model weights to build Encoder-Decoder architectures.
