## long-covid-classification
We fine-tuned bert-base-cased using a [manually curated dataset](https://huggingface.co/llangnickel/long-covid-classification-data) to train a Sequence Classification model able to distinguish between long COVID and non-long COVID-related documents. 

## Used hyper parameters
|Parameter|Value|
|---|---|  
|Learning rate|3e-5|
|Batch size|16|
|Number of epochs|4|
|Sequence Length|512|

## Metrics
|Precision [%]|Recall [%]|F1-score [%]|
|---|---|---|  
|91.18|91.18|91.18|

## How to load the model
```
from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("llangnickel/long-covid-classification", use_auth_token=True)
label_dict = {0: "nonLongCOVID", 1: "longCOVID"}
model = AutoModelForSequenceClassification.from_pretrained("llangnickel/long-covid-classification", use_auth_token=True, num_labels=len(label_dict))
```
