# {model_name}

This model is a fine-tuned version of [{language_model}](https://huggingface.co/{language_model}) on the [tweet_topic_multi](https://huggingface.co/datasets/cardiffnlp/tweet_topic_multi). {extra_desc}
Fine-tuning script can be found [here](https://huggingface.co/datasets/cardiffnlp/tweet_topic_multi/blob/main/lm_finetuning.py). It achieves the following results on the test_2021 set:

- F1 (micro): {metric['test/eval_f1']}
- F1 (macro): {metric['test/eval_f1_macro']}
- Accuracy: {metric['test/eval_accuracy']}


### Usage

```python
import math
import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

def sigmoid(x):
  return 1 / (1 + math.exp(-x))
  
tokenizer = AutoTokenizer.from_pretrained("{model_name}")
model = AutoModelForSequenceClassification.from_pretrained("{model_name}", problem_type="multi_label_classification")
model.eval()
class_mapping = model.config.id2label

with torch.no_grad():
  text = {sample}
  tokens = tokenizer(text, return_tensors='pt')
  output = model(**tokens)
  flags = [sigmoid(s) > 0.5 for s in output[0][0].detach().tolist()]
  topic = [class_mapping[n] for n, i in enumerate(flags) if i]
print(topic)
```
