Base Foundation Model: google/gemma-3-1b-it
Discipline: West-Brown-Enquist (WBE) Fractal Hydrodynamics, Critical Slowing Down (CSD), and Polypharmacy Hypergraphs
Open Science Provenance: Zenodo DOI 10.5281/zenodo.20647514


📌 Overview

Complex systems clinical engine developed in alignment with theoretical frameworks from the Santa Fe Institute and the ASU-SFI Center for Biosocial Complex Systems. Replaces naive linear (mg/kg) dosing with West-Brown-Enquist (WBE) M^0.75 fractal branching hydrodynamic network scaling. Detects physiological Critical Slowing Down (CSD) through lag-1 autocorrelation inflation (rho_1 -> 1) 2-48 hours before clinical collapse. Models non-linear simplicial hyperedge cascades across polypharmacy regimens and extreme environmental heat.

This LoRA adapter was fine-tuned using Direct Preference Optimization (DPO) on domain-specific clinical datasets conforming strictly to HIPAA §164.514 Safe Harbor de-identification standards.


🚀 Quickstart Inference (Transformers & PEFT)

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel

base_model_id = "google/gemma-3-1b-it"
adapter_id = "pocketgull-llc/pocketgull-allometric-sfi-1b"

tokenizer = AutoTokenizer.from_pretrained(base_model_id)
base_model = AutoModelForCausalLM.from_pretrained(
    base_model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)
model = PeftModel.from_pretrained(base_model, adapter_id)

prompt = "Patient presents with palpitations taking St. John's Wort alongside Warfarin. Evaluate CYP450 metabolism."
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")

with torch.no_grad():
    outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.2)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
