Usage
Example Usage
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
model_name = "your-username/llama3-dementia-care"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
model_name,
torch_dtype=torch.float16,
device_map="auto"
)
# Example conversation
messages = [
{"role": "system", "content": "You are a specialized assistant for dementia and memory care. Provide compassionate, accurate, and helpful information about dementia, Alzheimer's disease, caregiving strategies, and support resources. Always be empathetic and practical in your responses."},
{"role": "user", "content": "What are some strategies for managing sundown syndrome in dementia patients?"}
]
input_ids = tokenizer.apply_chat_template(messages, return_tensors="pt")
with torch.no_grad():
outputs = model.generate(
input_ids,
max_new_tokens=256,
temperature=0.7,
top_p=0.9,
top_k=50,
repetition_penalty=1.1,
do_sample=True
)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
Recommended Parameters
- Temperature: 0.7 (balanced creativity and consistency)
- Top-p: 0.9 (nucleus sampling)
- Top-k: 50 (vocabulary filtering)
- Max New Tokens: 256 (appropriate response length)
- Repetition Penalty: 1.1 (reduce repetition)
Limitations and Biases
Limitations
- Medical Scope: Not a replacement for professional medical advice
- Individual Variation: Cannot account for all individual differences
- Emergency Situations: Not suitable for crisis intervention
- Cultural Context: May reflect training data biases
Bias Considerations
- Training data primarily in English
- May reflect cultural perspectives from source materials
- Continuous monitoring and improvement needed
Ethical Considerations
Responsible Use
- Always emphasize the importance of professional medical consultation
- Respect dignity and autonomy of individuals with dementia
- Provide accurate, evidence-based information
- Support both patients and caregivers with empathy
Safety Measures
- Built-in safety filters for harmful content
- Emphasis on professional consultation for medical decisions
- Clear disclaimers about limitations
- Encouragement of appropriate resource utilization
