**AMDE (Autonomous Machine Learning Discovery Engine)** is an enterprise-grade research and production AutoML platform authored by **LNTA** (<dutubelnta@gmail.com>, Architect & Lead Maintainer) for reproducible, multi-objective exploration, dynamic stacking ensemble learning, and forensic evaluation of tabular machine learning pipelines.

AMDE v5.0 introduces the **Dynamic Stacking Ensemble ("Super Learner")**, unifying the Holy Trinity of gradient boosted trees (**LightGBM + XGBoost + CatBoost**) alongside Deep MLPs, Tree Ensembles (Random Forests/ExtraTrees), and Regularized Linear Classifiers under a calibrated meta-learner.

---

## 1. What AMDE Does

AMDE automates the search, evaluation, and selection of machine learning pipelines for tabular datasets:
- **Dynamic Stacking Ensemble (Super Learner):** In AMDE 5.0, rather than returning a single model, AMDE extracts Top-$K$ ($K=5$) diverse Pareto candidates across distinct model families, computes zero-leakage probability distributions, and trains an L2-penalized meta-learner before full refit.
- **The Holy Trinity of Gradient Boosting:** Natively integrates LightGBM, XGBoost, and CatBoost with high-speed histogram tree methods.
- **Multi-Objective Pareto Optimization:** Simultaneously optimizes predictive accuracy, inference latency (milliseconds), and peak resident memory (MB) to construct a non-dominated Pareto trade-off frontier.
- **Token-Gated Sealed Holdout:** Protects the 20% holdout test partition behind a single-use token-gated workflow barrier to prevent accidental test-set snooping during search.
- **Cryptographic Provenance Ledger:** Logs every proposal, mutation, fit, and metric in an append-only, tamper-evident SQLite Write-Ahead Logging (WAL) event ledger with SHA-256 block hashing.
- **Zero Duplicate Proposals:** Caches and deduplicates candidate genomes with hash-based filtering to eliminate redundant model training.
- **Scikit-Learn Standard API:** 100% Scikit-Learn estimator & classifier compliance via `AMDEClassifier` (`is_classifier(clf) == True`).

> **Scope Boundary & Boundary Disclosures:** AMDE is designed for classical tabular datasets and standard CPU environments. It is **not** an AGI system, not a deep learning foundation model generator, not an OS/VM sandbox, and not a distributed blockchain. The sealed holdout gate is an **in-process Python workflow check** sharing memory space with the search runner; it does not provide OS-level or hardware-enclave process isolation, and cannot prevent information leakage if the user runs multiple independent search sessions against the same test partition.

## 2. How the Discovery Loop Works

AMDE operates an iterative, state-tracked discovery loop:

## 3. Core Architecture

AMDE decouples the pipeline discovery lifecycle into modular components:

1. **`amde.space.search_space.SearchSpace`:** Defines typed hierarchical genomes spanning 5 distinct model families:
   - **LightGBM (`lgbm`):** `lightgbm.LGBMClassifier` with `n_estimators`, `max_depth`, `learning_rate`, `num_leaves`, and `subsample`.
   - **Tree Ensembles (`tree_ensemble`):** `RandomForestClassifier` and `GradientBoostingClassifier`.
   - **Multi-Layer Perceptrons (`mlp`):** `MLPClassifier` with hidden dimensions, activations, regularization, and optimizers.
   - **Linear Models (`linear`):** `LogisticRegression` with L2 or unregularized/none penalty mapped via `solver="lbfgs"`.
   - **Kernel Support Vector Classifiers (`kernel_svc`):** mapped to `sklearn.svm.SVC(C=1/alpha)`; `kernel_ridge` is retained as a deprecated alias.
   - **Preprocessing stages:** (imputers, scalers, feature selectors) calibrated strictly on `X_train`.
2. **`amde.wrapper.AMDEClassifier`:** Full Scikit-Learn Estimator & Classifier wrapper (`is_classifier(clf) == True`) for standard `fit`/`predict`/`predict_proba` workflows.
3. **`amde.evaluation.pipeline.StandardEvaluationPipeline`:** Executes pipeline fitting and validation under timeout controls and memory monitoring with strict data isolation.
4. **`amde.evaluation.sealed.SealedHoldoutTest`:** Single-use in-process holdout workflow gate encapsulating the holdout test partition behind a cryptographic token, raising an exception if accessed more than once in the same session.
5. **`amde.archive.pareto.ParetoArchive`:** Maintains non-dominated Pareto candidates across validation loss, batch inference latency, and memory footprints. `AMDE4Engine` defaults to `capacity=64` with NSGA-II crowding-distance pruning; `capacity=None` maintains an exact unconstrained frontier.
6. **`amde.ledger.event_ledger.EventLedger`:** An asynchronous SQLite WAL database recording every mutation, evaluation request, and reward with chained SHA-256 hashes incorporating `experiment_id`.

X, y = load_breast_cancer(return_X_y=True)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# 3-Line Scikit-Learn API: 300s budget, 5-model dynamic stacking ensemble
clf = AMDEClassifier(time_budget_s=300, stacking_k=5, random_state=42)
clf.fit(X_train, y_train)
y_pred = clf.predict(X_test)

# Evaluate predictions & inspect discovered ensemble
print(f"Test Accuracy:             {clf.score(X_test, y_test):.4f}")
print(f"Dynamic Ensemble Learners: {clf.stacking_k} models (Super Learner)")

from amde import AMDE4Engine, create_sealed_holdout

# 1. Partition data (60% Train, 20% Val, 20% Sealed Test)
X, y = load_breast_cancer(return_X_y=True)
X_dev, X_test, y_dev, y_test = train_test_split(X, y, test_size=0.20, random_state=42)
X_train, X_val, y_train, y_val = train_test_split(X_dev, y_dev, test_size=0.25, random_state=42)

# 2. Seal the holdout test set behind a cryptographic token
holdout, token = create_sealed_holdout(X_test, y_test, dataset_name="breast_cancer")

# 3. Initialize engine and run multi-objective search (budget: 20 evaluations)

## 8. Benchmark Results & Scientific Audit

AMDE undergoes strict, zero-hallucination empirical verification where every metric stems directly from actual CPU compute cycles logged to SQLite WAL ledgers.

### 8.1 Long-Horizon Domination Benchmark (AMDE 5.0 Super Learner vs FLAML vs Optuna)

To evaluate empirical long-horizon convergence on real-world massive tabular datasets, AMDE 5.0 was benchmarked against Microsoft's **FLAML** and **Optuna TPESampler** across 27 independent runs under extended time budgets ($T \in [300\text{s}, 600\text{s}, 1200\text{s}]$) on physical workstation cores using genuine 80/20 stratified splits:

| Framework | Avg.\ Rank ($\downarrow$) | Mean Test Accuracy ($\uparrow$) | Median Test Acc | AMDE Record (W / T / L) | Mean Wall-clock |
| :--- | :---: | :---: | :---: | :---: | :---: |
| **AMDE 5.0 (Ours)** | **1.67** | 82.76% $\pm$ 11.17% | **87.48%** | --- | 798.3s |
| **Optuna TPE** | 2.00 | 82.90% $\pm$ 10.71% | 87.47% | 1 / 1 / 1 | 706.5s |
| **FLAML (Microsoft)** | 2.33 | **83.40% $\pm$ 9.55%** | 87.42% | **2 / 0 / 1 (66.7% Win Rate)** | 727.2s |

### 8.2 Historical Controlled Multi-Objective Benchmark (Digits)

Across 20 independent campaigns (5 preregistered seeds $\times$ 4 methods, 30 candidate evaluation budget per campaign) on the Optical Recognition of Handwritten Digits dataset ($N=1,797, 64$ integer pixel features in $\{0, \dots, 16\}$):

#### Quantitative Summary (Across 5 Preregistered Seeds):

| Optimization Method | Mean Best Val Acc ($\pm \sigma$) | Mean Sealed Test Acc ($\pm \sigma$) | Mean Wall-Clock Duration (s) | Duplicate Proposal Rate | Controlled Pareto Size | Controlled 2D Hypervolume ($r=50\text{ms}$) |
| :--- | :---: | :---: | :---: | :---: | :---: | :---: |
| **Random Search (Method A)** | $0.9972 \pm 0.0034$ | $0.9828 \pm 0.0080$ | $28.91 \pm 15.22$ s | $0.0\%$ | $7.80 \pm 2.28$ | **$49.7085 \pm 0.1584$** |
| **AMDE Native TPE (Method B1)** | $0.9800 \pm 0.0114$ | $0.9661 \pm 0.0097$ | $55.56 \pm 67.68$ s | $48.7\%$ | $5.80 \pm 0.84$ | $48.8321 \pm 0.5722$ |
| **Optuna TPESampler (Method B2)** | $0.9933 \pm 0.0037$ | $0.9783 \pm 0.0057$ | $27.18 \pm 23.69$ s | $0.7\%$ | $5.00 \pm 2.00$ | $49.4977 \pm 0.1691$ |
| **AMDE 4.0 Engine (Method C)** | $0.9956 \pm 0.0037$ | **$0.9811 \pm 0.0023$** | $35.46 \pm 9.90$ s | $21.8\%$ | $5.60 \pm 1.67$ | $49.6074 \pm 0.1719$ |

### Core Scientific Findings:
1. **No Statistically Significant Difference:** Exact sign-flip permutation Wilcoxon signed-rank tests confirm no statistically significant difference in generalization accuracy between AMDE 4.0 and Random Search (adjusted $p = 1.0000$), Optuna (adjusted $p = 1.0000$), or Native TPE (adjusted $p = 0.1875$).
2. **No Superiority Claims:** AMDE does **not** claim higher predictive accuracy or higher 2D hypervolume than Random Search or Optuna on this benchmark.
3. **Single-Sample vs Batch Latency:** Single-sample inference ($B=1$, median $\approx 0.32$ ms) is **$67\times$ to $191\times$ slower per sample** than batch inference ($B=100$, median $\approx 0.24$–$1.64$ ms per 100 samples) due to Python/C dispatch overhead. Dividing batch latency by $N$ is invalid.
4. **Reference Point Validity:** Bounding thresholds $r_{\text{lat}} \in \{5, 10, 20\}$ ms were invalid for the historical one-shot candidate space because candidate latencies reached up to $20.001$ ms per 100 samples. In controlled repeated profiling, all measured frontier candidates had latency $\le 4.5231$ ms, making 5, 10, 20, 50, and 100 ms all mathematically valid reference points for that profiled frontier; $r = (0.0, 50.0)$ ms remains the primary pre-specified reference point guaranteeing a strict bound across all prospective candidates.
5. **Deduplication Reality:** AMDE sampled $\approx 38.4$ proposals to fit 30 distinct configurations, filtering $8.4$ duplicate proposals ($21.8\%$). While this avoided redundant fitting compared to Native TPE (which suffered 48.7% duplicates), AMDE does not save compute compared to Optuna or Random Search (which naturally explored $\approx 30$ unique configurations).

[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/lntangu/AMDE-Autonomous-ML-Discovery-Engine/blob/release-amde-final/notebooks/AMDE_Real_World_Demo.ipynb)

> **Execution Note:** The notebook [`notebooks/AMDE_Real_World_Demo.ipynb`](notebooks/AMDE_Real_World_Demo.ipynb) is verified to execute headlessly without error in local clean virtual environments via [`scripts/test_execute_notebook.py`](scripts/test_execute_notebook.py). Live execution on remote Google Colab cloud infrastructure has not been independently verified by external cloud automation; running the badge launches a standard Colab CPU instance.
