# Pre-trained BERT on Twitter US Political Election 2020 |
|
|
|
Pre-trained weights for [Knowledge Enhance Masked Language Model for Stance Detection](https://2021.naacl.org/program/accepted/), NAACL 2021. |
|
|
|
We use the initialized weights from BERT-base (uncased) or `bert-base-uncased`. |
|
|
|
# Training Data |
|
|
|
This model is pre-trained on over 5 million English tweets about the 2020 US Presidential Election. |
|
|
|
# Training Objective |
|
|
|
This model is initialized with BERT-base and trained with normal MLM objective. |
|
|
|
# Usage |
|
|
|
This pre-trained language model **can be fine-tunned to any downstream task (e.g. classification)**. |
|
|
|
