# cardiffnlp/twitter-roberta-base-2019-90m-tweet-topic-multi-all

This model is a fine-tuned version of [cardiffnlp/twitter-roberta-base-2019-90m](https://huggingface.co/cardiffnlp/twitter-roberta-base-2019-90m) on the [tweet_topic_multi](https://huggingface.co/datasets/cardiffnlp/tweet_topic_multi). This model is fine-tuned on `train_all` split and validated on `test_2021` split of tweet_topic.
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): 0.7625128733264676
- F1 (macro): 0.6035334168546909
- Accuracy: 0.547945205479452


### Usage

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

def sigmoid(x):
  return 1 / (1 + math.exp(-x))
  
tokenizer = AutoTokenizer.from_pretrained("cardiffnlp/twitter-roberta-base-2019-90m-tweet-topic-multi-all")
model = AutoModelForSequenceClassification.from_pretrained("cardiffnlp/twitter-roberta-base-2019-90m-tweet-topic-multi-all", problem_type="multi_label_classification")
model.eval()
class_mapping = model.config.id2label

with torch.no_grad():
  text = #NewVideo Cray Dollas- Water- Ft. Charlie Rose- (Official Music Video)- {{URL}} via {@YouTube@} #watchandlearn {{USERNAME}}
  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)
```
