# LEAF: Predicting the Environmental Impact of Food Products based on their Name

The `leaf-large` model is
a [`BAAI/bge-m3`](https://huggingface.co./BAAI/bge-m3)
model fine-tuned on the [LEAF dataset](https://huggingface.co./datasets/baskra/LEAF).

To load the model, use the following code:

```python
from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("baskra/leaf-base")
model = AutoModel.from_pretrained("baskra/leaf-base", trust_remote_code=True)

model(**tokenizer("Nutella", return_tensors="pt"))
# {'logits': tensor([[-12.2842, ...]]), 'class_idx': tensor([1553]), 'ef_score': tensor([0.0129]), 'class': ['Chocolate spread with hazelnuts']}
```

    abstract = "Although food consumption represents a sub- stantial global source of greenhouse gas emis- sions, assessing the environmental impact of off-the-shelf products remains challenging. Currently, this information is often unavailable, hindering informed consumer decisions when grocery shopping. The present work introduces a new set of models called LEAF, which stands for Linguistic Environmental Analysis of Food Products. LEAF models predict the life-cycle environmental impact of food products based on their name. It is shown that LEAF models can accurately predict the environmental im- pact based on just the product name in a multi- lingual setting, greatly outperforming zero-shot classification methods. Models of varying sizes and capabilities are released, along with the code and dataset to fully reproduce the study.",
