Branches

Original model

Original : Code optimized compared to the the original repo leading to faster training time
Uses GloVe, Elmo, and a fine tuned character embedding.

Ablative models

NoStatic : Removed GloVe embedding from orignal model
NoContext : Removed Elmo embedding from orignal model
NoChar : Removed character embedding from orignal model
noctx-static : Removed Elmo and GloVe embedding from orignal model
noctx-static-char : Removed all embedding from orignal model

Comparative models

GPT-2 : Replace Elmo with GPT-2
BERT : Replace Elmo with BERT
FastText : Replace GloVe with FastText
Word2Vec : Replace GloVe with Word2Vec

Comparative ablative models

Onlybert : Removed GloVe and character embedding from orignal model + Replace Elmo with BERT
OnlyGPT : Removed GloVe and character embedding from orignal model + Replace Elmo with GPT-2
OnlyELMO : Removed GloVe and character embedding from orignal model
onlyfasttext : Removed Elmo and character embedding from orignal model + Replace GloVe with FastText
onlyword2vec : Removed Elmo and character embedding from orignal model + Replace GloVe with Word2Vec
onlyglove : Removed Elmo and character embedding from orignal model
