BERT is a well-known and powerful pre-trained “encoder” model. Let’s see how we can use it as a “decoder” to form an encoder-decoder architecture.

The Transformer architecture consists of two main building blocks — encoder and decoder components — which we stack on top of each other to form a seq2seq model. (You can read more about it in my previous story) It is generally hard to train a transformer-based model from scratch since it needs both large datasets and high GPU memory. So, there are numerous pre-trained models with different objectives in mind.

Firstly, the encoder… Read the full blog for free on Medium.
