Build other transformer models

[vatsal2473]

We are currently using RoBERTa model as a baseline for both the subtasks

• Build other different transformer models such as

• BERT
• SPECTER
• XLNET
• PubMedBERT
• SciBERT

and there are many other models for NLP you can build as long as its giving better scores than the RoBERTa baseline model

• Also build the model in different notebooks for both the subtasks
