DOLPHIN/mc_forewarning_qlabs_fork

MC Forewarning System - QLabs Enhanced Fork

A research fork of the Nautilus-Dolphin Monte Carlo Forewarning System, enhanced with QLabs Slowrun ML techniques.

---

Overview

This repository contains an isolated, enhanced version of the MC-Forewarning subsystem from the Nautilus-DOLPHIN trading system. It implements QLabs' cutting-edge ML techniques from the NanoGPT Slowrun benchmark to improve data efficiency and prediction accuracy.

QLabs Techniques Implemented

#	Technique	Implementation	Expected Benefit
1	Muon Optimizer	mc_ml_qlabs.py:MuonOptimizer	Orthogonalized gradient updates for stable convergence
2	Heavy Regularization	QLabsHyperParams.xgb_reg_lambda=1.6	16× weight decay enables larger models on limited data
3	Epoch Shuffling	_shuffle_epochs()	Reshuffle data each epoch for better generalization
4	SwiGLU Activation	mc_ml_qlabs.py:SwiGLU	Gated MLP activations (Swish + Gating)
5	U-Net Skip Connections	mc_ml_qlabs.py:UNetMLP	Encoder-decoder with residual pathways
6	Deep Ensembling	mc_ml_qlabs.py:DeepEnsemble	Logit averaging across 8 models

Quick Start

1. Setup Environment

# Install dependencies
pip install numpy pandas scikit-learn xgboost torch

# Optional: For running full Nautilus-Dolphin backtests
pip install -r ../requirements.txt

2. Generate MC Trial Corpus

# Generate synthetic trial data for testing
python -c "
from mc.mc_runner import run_mc_envelope
run_mc_envelope(
    n_samples_per_switch=100,
    max_trials=1000,
    n_workers=4,
    output_dir='mc_forewarning_qlabs_fork/results'
)
"

3. Run Benchmark Comparison

# Compare Baseline vs QLabs-enhanced models
python benchmark_qlabs.py \
    --data-dir mc_forewarning_qlabs_fork/results \
    --output-dir mc_forewarning_qlabs_fork/benchmark_results \
    --ensemble-size 8

4. Train QLabs Models Only

python -c "
from mc.mc_ml_qlabs import MCMLQLabs

ml = MCMLQLabs(
    output_dir='mc_forewarning_qlabs_fork/results',
    use_ensemble=True,
    n_ensemble_models=8,
    use_unet=True,
    use_swiglu=True,
    heavy_regularization=True
)

result = ml.train_all_models(test_size=0.2, n_epochs=12)
print(f'Training complete: {result}')
"

5. Run Live Forewarning

# Start the forewarning service
python mc_forewarning_service.py

# Or use QLabs-enhanced forewarner programmatically
python -c "
from mc.mc_ml_qlabs import DolphinForewarnerQLabs
from mc.mc_sampler import MCSampler

forewarner = DolphinForewarnerQLabs(
    models_dir='mc_forewarning_qlabs_fork/results/models_qlabs'
)

sampler = MCSampler()
config = sampler.generate_champion_trial()

report = forewarner.assess(config)
print(f'Risk Level: {report.envelope_score:.3f}')
print(f'Catastrophic Prob: {report.catastrophic_probability:.1%}')
"

Key Differences: Baseline vs QLabs

Baseline (mc_ml.py)

# Single GradientBoostingRegressor
model = GradientBoostingRegressor(
    n_estimators=100,
    max_depth=5,
    learning_rate=0.1,
    random_state=42
)

# Single XGBClassifier
model = xgb.XGBClassifier(
    n_estimators=100,
    max_depth=5,
    learning_rate=0.1,
    random_state=42
)

# Single OneClassSVM for envelope
model = OneClassSVM(kernel='rbf', nu=0.05, gamma='scale')

QLabs Enhanced (mc_ml_qlabs.py)

# Deep Ensemble of 8 models
ensemble = DeepEnsemble(
    GradientBoostingRegressor,
    n_models=8,
    seeds=[42, 43, 44, 45, 46, 47, 48, 49]
)

# Heavy regularization (16× weight decay)
model = xgb.XGBClassifier(
    n_estimators=200,
    max_depth=5,
    learning_rate=0.05,
    reg_lambda=1.6,        # ← QLabs: 16× standard
    reg_alpha=0.1,
    subsample=0.8,
    colsample_bytree=0.8,
)

# Ensemble of One-Class SVMs with different nu
ensemble_svm = [
    OneClassSVM(kernel='rbf', nu=0.05 + i*0.02, gamma='scale')
    for i in range(8)
]

Integration with Nautilus-Dolphin

This fork is fully isolated from the main Nautilus-Dolphin system. To integrate:

1. Copy the enhanced module to your ND installation:

   cp mc_forewarning_qlabs_fork/mc/mc_ml_qlabs.py nautilus_dolphin/mc/
   

2. Update imports in your code:

   # Old (baseline)
   from mc.mc_ml import DolphinForewarner
   
   # New (QLabs enhanced)
   from mc.mc_ml_qlabs import DolphinForewarnerQLabs
   

3. Retrain models with QLabs enhancements:

   from mc.mc_ml_qlabs import MCMLQLabs
   
   ml = MCMLQLabs(use_ensemble=True, n_ensemble_models=8)
   ml.train_all_models()
