# roberta-base + DAPT + Domain-Specific QA

Objective:
  This is Roberta Base with Domain Adaptive Pretraining on Movie Corpora --> Then a changed head to do the SQuAD Task. This makes a QA model capable of answering questions in the movie domain.  
  https://huggingface.co/thatdramebaazguy/movie-roberta-base was used as the MovieRoberta.
  
```
model_name = "thatdramebaazguy/movie-roberta-squad"
pipeline(model=model_name, tokenizer=model_name, revision="v1.0", task="question-answering")
```

## Overview
**Language model:** roberta-base  
**Language:** English  
**Downstream-task:** QA  
**Training data:** imdb, polarity movie data, cornell_movie_dialogue, 25mlens movie names, SQuADv1  
**Eval data:** MoviesQA (From https://github.com/ibm-aur-nlp/domain-specific-QA)  
**Infrastructure**: 1x Tesla v100   
**Code:**  See [example](https://github.com/adityaarunsinghal/Domain-Adaptation/blob/master/scripts/shell_scripts/train_movieR_just_squadv1.sh)    

## Hyperparameters
```
Num examples = 88567  
Num Epochs = 10
Instantaneous batch size per device = 32  
Total train batch size (w. parallel, distributed & accumulation) = 32  

``` 
## Performance

### Eval on MoviesQA
- eval_samples =    5032
- exact_match = 51.64944
- f1 = 65.53983

### Eval on SQuADv1
- exact_match  = 81.23936
- f1           = 89.27827
