```


### Basic Usage

```python
from octolearn import AutoML
from sklearn.datasets import load_iris

# Load your dataset
data = load_iris(as_frame=True)
X, y = data.data, data.target

# User-driven preprocessing: override imputer, encoder, scaler, and ID columns
user_params = {
   'imputer_strategy': {'numeric': 'median', 'categorical': 'mode'},
   'encoder_strategy': {'ordinal_cols': ['petal length (cm)'], 'bool_cols': ['sex']},
   'scaler': 'standard',
   'id_columns': ['sample_id']
}

# Initialize and fit with user params
automl = AutoML(**user_params)
automl.fit(X, y)

# Generate comprehensive report (modern black/red PDF)
pdf_file = automl.generate_report()
print(f"Report saved: {pdf_file}")
# Output: octolearn_report_<hash>.pdf

# All trained models are saved in trained_models/ and tracked in the registry
```

### Access Individual Analyses

```python
# Get dataset risk score
risk = automl.get_risk_score()
print(f"Risk Score: {risk['score']}/100")
print(f"Category: {risk['category']}")

# Get feature importance
importance = automl.get_feature_importance()
for feature, score in list(importance.items())[:5]:
    print(f"{feature}: {score:.4f}")

# Get preprocessing suggestions
suggestions = automl.get_preprocessing_suggestions()
for strategy, recs in suggestions.items():

- **Transparent**: Access every intermediate result, log, and artifact.
- **Production-ready**: Used in real-world projects, with robust error handling and logging.

---

## ⚡ Quick Start

### Installation

```bash
pip install octolearn
```

### Minimal Usage

```python
from octolearn import AutoML
import pandas as pd

df = pd.read_csv('your_data.csv')
X = df.drop('target', axis=1)
y = df['target']

# All defaults, full pipeline
automl = AutoML()
automl.fit(X, y)
pdf = automl.generate_report()
print(f"Report: {pdf}")
```

---

## 🛠️ Full User-Param Control

```python
automl = AutoML(
    imputer_strategy={"numeric": "median", "categorical": "mode"},
    encoder_strategy={"ordinal_cols": ["grade"], "default": "ohe"},
    scaler="minmax",
    id_columns=["id", "customer_id"],
    train_models=True,
    use_registry=True,
    n_models=3,
    evaluation_metric="f1",
    parallel_processing=True
)
automl.fit(X, y)
results = automl.train_auto_models()
pdf = automl.generate_report()
```
- **Dataset Profiling**: `profiling/data_profiler.py` performs automatic type detection (numeric, categorical, datetime), missing-value summaries, duplicate detection, skewness and constant-column checks, high-cardinality detection, and produces a stable dataset hash.

---

## 🔥 Key Features & Power

- **User-param driven preprocessing**: Imputer, encoder, scaler, and ID columns are all user-overridable at any point.
- **ID column handling**: Any columns listed in `id_columns` are never used for modeling or predictions, but are preserved for merging and reference.
- **Model registry**: Every trained model is saved in `trained_models/` and tracked in the registry with full metadata (parameters, metrics, version, hash).
- **Model benchmarks/results table**: PDF report includes a table of all trained models, their parameters, and all metrics, with the best model at the top (by your chosen metric).
- **User-param driven evaluation metric**: Select the metric (e.g., F1, RMSE, accuracy, etc.) for best model selection and benchmarking.
- **Professional PDF reporting**: Black background, red accents, modern font, and full transparency of all results.
- **Access at every point**: Access cleaned data, profile, outlier analysis, feature interactions, cleaning log, all trained models, best model, and model benchmarks at any time.
- **Extensible and modular**: Add your own models, metrics, or reporting sections with minimal code changes.
- **API-first**: All phases and results are accessible via the API.
- **Production-grade error handling and logging**: Robust, clear, and debug-friendly.

## 🐙 Philosophy

> "Build the skeleton first. Then make it breathe."

Octolearn follows modular, automated, and professional principles:
- ✅ **Modular Architecture** - Each component independent
- ✅ **Automation First** - Recommendations, not questions
- ✅ **Professional Quality** - Production-ready outputs
- ✅ **Reproducible Results** - Hash-based naming
- ✅ **Zero Configuration** - Works out of the box
- ✅ **User-Param Driven** - Full control at every step

---

**Made with ☕ and 🐙 Logic.**
- **Risk Scoring**: `experiments/risk_scorer.py` computes a 0–100 data quality risk score and returns contributing factors and a categorical label (Low / Moderate / High).
- **Preprocessing Suggestions**: `experiments/preprocessing_suggester.py` generates actionable strategies for imputation, encoding, scaling, cardinality handling, and column-specific actions.
- **Baseline Feature Importance**: `experiments/baseline_importance.py` trains a fast Random Forest baseline to produce feature importances.
- **Explainability (SHAP)**: `experiments/plot_generator.py` integrates SHAP `TreeExplainer` to produce SHAP summary plots and an importance bar chart for tree-based models.
- **Visual Diagnostics**: `experiments/plot_generator.py` creates per-feature distribution plots, correlation heatmaps, and saves PNG artifacts (non-interactive `Agg` backend supported).
- **Automated PDF Report**: `experiments/report_generator.py` composes a professional PDF dossier that embeds executive summary, risk banner, preprocessing suggestions, baseline importance, and visual diagnostics.
- **Recommendation Engine**: `experiments/recommendation_engine.py` synthesizes profiling and model signals into concise, prioritized recommendations.
- **Core API / Orchestration**: `core.py` exposes the high-level `AutoML` class with methods `fit(X, y)`, `generate_report()`, `get_risk_score()`, `get_preprocessing_suggestions()`, `get_feature_importance()`, and `report()` (raw profile).
- **Model & Optimization Utilities**: `models/` (selector & registry) and `optimization/optimizer.py` provide foundations for model selection and future HPO workflows.
- **Preprocessing Pipeline Builder**: `preprocessing/pipeline_builder.py` offers utilities to construct reproducible sklearn-compatible pipelines from suggested strategies.
- **Feature Engineering & Selection**: `feature/feature_engineer.py` and `feature/feature_selector.py` include initial helpers for transformations and automatic selection heuristics.
- **Evaluation & Metrics**: `evaluation/metrics.py` contains common evaluation helpers used by experiments and baseline checks.
- **Tracking & Utilities**: `experiments/tracker.py` plus `utils/helpers.py` provide lightweight run-tracking, reproducibility helpers, and I/O utilities.
- **Fonts & Assets**: `fonts/` contains font assets used when rendering the PDF reports for consistent professional typography.

These components are designed to work together end-to-end: run `AutoML().fit(X,y)` to create a `DatasetProfile`, inspect suggestions and risks via the API, and call `generate_report()` to produce a stakeholder-ready PDF report and visual artifacts.
