How to Use

python

from transformers import DistilBertTokenizer, DistilBertForSequenceClassification
import torch

# Load model
tokenizer = DistilBertTokenizer.from_pretrained("franzzzzzzzzz/tpb-perceived-control-nutrition")
model = DistilBertForSequenceClassification.from_pretrained("franzzzzzzzzz/tpb-perceived-control-nutrition")

# Predict
text = "I love healthy food, it's amazing!"
inputs = tokenizer(text, return_tensors='pt', padding=True, truncation=True)
outputs = model(**inputs)
prediction = torch.argmax(outputs.logits, dim=1).item()

# Convert 0-4 to 1-5 scale
score = prediction + 1
print(f"Score: {score}/5")

Limitations

Trained on English text only
Limited to nutrition/dietary contexts
May not generalize to other health behaviors
Requires context-appropriate input
