Model Description

Fine-tuned DistilBERT model for classifying stage of change (pre-contemplation, contemplation, preparation, action, maintenance) based on the Transtheoretical Model (TTM) for nutrition behavior change.

This model is a fine-tuned version of distilbert-base-uncased for behavior change inference in nutrition coaching contexts.

Training Data

• Training samples: 175
• Validation samples: 25
• Test samples: 50
• Total: 250 samples

Performance

• Test Accuracy: 84.0%

Intended Use

This model is designed for:

• Nutrition coaching chatbots
• Behavior change interventions
• Health psychology research
• Personalized dietary guidance

How to Use

from transformers import DistilBertTokenizer, DistilBertForSequenceClassification
import torch

# Load model
tokenizer = DistilBertTokenizer.from_pretrained("franzzzzzzzzz/ttm-stage-nutrition")
model = DistilBertForSequenceClassification.from_pretrained("franzzzzzzzzz/ttm-stage-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
