Siamese Multi-depth Transformer-based Hierarchical Encoder

🌟 New model addition

Model description

Recently Google is published paper titled "Beyond 512 Tokens: Siamese Multi-depth Transformer-based Hierarchical Encoder for Long-Form Document Matching". And according to paper for long-form document matching SMITH model outperforms the previous state-of-the-art models including hierarchical attention, multi-depth attention-based hierarchical recurrent neural network, and BERT.

I feel it is will add value to already awesome transformers models collection 🙂

Frequent user of hugging face here, I'm a fan of this new publication and would love to see it implemented. Commenting here for the GitHub algorithm to ++

Hi all, rather than waiting for the implementation in huggingface. Is there a simple way to utilize the pretrained model from the smith repo on our own dataset (to generate document embedding)?
