# Description:

climateattention-ctw classifies if a given sequence is related to climate topics. 
As a fine-tuned classifier based on climatebert/distilroberta-base-climate-f (Webersinke et al., 2021), 
it is using the following ClimaText dataset (Varini et al., 2020):

* Wiki-doc corpus, with 115847 samples (57922 positives, 57925 negatives)

For company disclosures or news articles you might want to check the 10k model: kruthof/climateattention-10k-upscaled
# How to use:
```python
from transformers import AutoTokenizer, pipeline,RobertaForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("climatebert/distilroberta-base-climate-f")
climateattention = RobertaForSequenceClassification.from_pretrained('kruthof/climateattention-ctw',num_labels=2)

ClimateAttention = pipeline("text-classification", model=climateattention, tokenizer=tokenizer)

ClimateAttention('Emissions have increased during the last several months')

>> [{'label': 'Yes', 'score': 0.9993829727172852}]

```
 # Performance:

Performance tested on the balanced ClimaText Wiki-doc test set, featuring 3826 samples (1913 positives, 1913 negatives) (Varini et al., 2020)

|Accuracy|  Precision | Recall  |   F1   |  
|----|-----|-----|-----|
| 0.8834   |  0.8717    |  0.8991 | 0.8852 |
