# ComVE-gpt2-medium |
|
|
|
## Model description |
|
|
|
Finetuned model on Commonsense Validation and Explanation (ComVE) dataset introduced in [SemEval2020 Task4](https://competitions.codalab.org/competitions/21080) using a causal language modeling (CLM) objective. |
|
The model is able to generate a reason why a given natural language statement is against commonsense. |
|
|
|
## Intended uses & limitations |
|
|
|
You can use the raw model for text generation to generate reasons why natural language statements are against commonsense. |
|
|
|
#### How to use |
|
|
|
You can use this model directly to generate reasons why the given statement is against commonsense using [`generate.sh`](https://github.com/AliOsm/SemEval2020-Task4-ComVE/tree/master/TaskC-Generation) script. |
|
|
|
*Note:* make sure that you are using version `2.4.1` of `transformers` package. Newer versions has some issue in text generation and the model repeats the last token generated again and again. |
|
|
|
#### Limitations and bias |
|
|
|
The model biased to negate the entered sentence usually instead of producing a factual reason. |
|
|
|
## Training data |
|
|
|
The model is initialized from the [gpt2-medium](https://github.com/huggingface/transformers/blob/master/model_cards/gpt2-README.md) model and finetuned using [ComVE](https://github.com/wangcunxiang/SemEval2020-Task4-Commonsense-Validation-and-Explanation) dataset which contains 10K against commonsense sentences, each of them is paired with three reference reasons. |
|
|
|
## Training procedure |
|
|
|
Each natural language statement that against commonsense is concatenated with its reference reason with `<|continue|>` as a separator, then the model finetuned using CLM objective. |
|
The model trained on Nvidia Tesla P100 GPU from Google Colab platform with 5e-5 learning rate, 5 epochs, 128 maximum sequence length and 64 batch size. |

## Eval results |
|
|
|
The model achieved fifth place with 16.7153/16.1187 BLEU scores and third place with 1.94 Human Evaluation score on SemEval2020 Task4: Commonsense Validation and Explanation development and testing dataset. |
|
|
|
These are some examples generated by the model: |
