Eeyore: Realistic Depression Simulation via Expert-in-the-Loop Supervised and Preference Optimization
Venue: ACL 2025 (Findings)
Paper: ACL Anthology
Overview
Eeyore introduce a Structured Alignment Framework that incorporates human experts. The framework contains three stages: data curation, instruction tuning, and preference optimization. It aims to create realistic simulations of individuals experiencing depression.
Key Features
- Data Curation: Mined real-world depression-related conversations from public sources
(e.g., depression subreddits, counseling transcripts)
- Psychological Profile Construction: A detailed structured profile containing different dimensions (DSM-V standards and Beck's cognitive theory)
- Instruction Tuning & DPO: To align the model closer to clinical expert expectations
Usage
CLI
uv run python -m examples.simulate client=eeyore therapist=user
Python
from omegaconf import OmegaConf
from patienthub.clients import get_client
config = OmegaConf.create({
'agent_type': 'eeyore',
'model_type': 'LOCAL',
'model_name': 'hosted_vllm//data3/public_checkpoints/huggingface_models/Eeyore_llama3.1_8B',
'temperature': 0.7,
'max_tokens': 1024,
'max_retries': 3,
'data_path': 'data/characters/Eeyore.json',
'data_idx': 0,
})
client = get_client(configs=config, lang='en')
client.set_therapist({'name': 'Clinician'})
response = client.generate_response("How have you been sleeping lately?")
print(response)
⚠️ Hint:
- Start a local OpenAI-compatible model server (e.g., vLLM) to serve the weights.
- Set
LOCAL_BASE_URL; PatientHub passes them asapi_base/api_keyto LiteLLM.- Use
model_type=LOCALand setmodel_nameto your served model id/name.- Run:
uv run python -m examples.simulate client=eeyore therapist=user

Example Conversation
Clinician: "Hi Sam, thank you for coming in. How have you been feeling lately?"
Patient (Eeyore): "sighs I don't know... just tired, I guess. Everything feels like such an effort. Even getting out of bed this morning took everything I had."
Clinician: "It sounds like you're experiencing a lot of fatigue. How long has this been going on?"
Patient: "Months now. I used to love going to yoga, seeing friends... now I can't remember the last time I did either. What's the point, really?"
Clinician: "You mentioned you used to enjoy yoga and seeing friends. What changed?"
Patient: "I lost my job back in March. I keep telling myself I'll start applying for new ones, but every time I sit down to work on my resume, I just... can't. I stare at the screen and think, 'Why would anyone hire me anyway?'"
