> **The only Python package that acts like a Senior Risk Data Scientist**

AutoRiskML automates the entire risk modeling pipeline from data ingestion to Azure deployment. Built for banks, fintechs, trading firms, and hedge funds.

## 🎯 Why AutoRiskML is Revolutionary

### ❌ **The Problem**

Risk data scientists spend 80% of their time on:
- Manual data cleaning and binning
- Computing WOE/IV tables
- Monitoring PSI and drift
- Building scorecards
- Setting up model monitoring
- Creating deployment pipelines

### ✅ **The Solution: AutoRiskML**

```python
from autoriskml import AutoRisk

# ONE command does EVERYTHING a senior risk DS would do:
ar = AutoRisk(project="loan_scoring")
ar.register_source("train", csv="data/loans.csv")
result = ar.run(
    source="train",
    target="default_flag",
    explain=True,
    deploy={"provider": "azure_ml"}
)

# You now have:
# ✅ Data profile & recommendations
# ✅ Automated cleaning
# ✅ Optimal binning & WOE/IV tables
# ✅ Trained scorecard model
# ✅ PSI & drift monitoring
# ✅ SHAP explainability
# ✅ Production-ready Azure deployment
# ✅ PDF/HTML reports
```

## 🔥 What AutoRiskML Does

### A. Automated Risk ML Pipeline

```python
# 1. DATA PROFILING - Like a senior DS would analyze
ar.profile()
# → Column types, missing %, distributions, recommendations

# 2. AUTO-CLEANING - Handles all edge cases
ar.autoclean()
# → Missing values, outliers, type coercion, date parsing

# 3. FEATURE ENGINEERING - Risk-specific features
ar.auto_features()
# → Binning, WOE encoding, interaction features

# 4. MODEL TRAINING - Multiple algorithms
ar.train(models=["logistic", "xgboost", "lightgbm"])
# → Auto hyperparameter tuning, walk-forward validation

# 5. SCORECARD GENERATION - Convert to points
ar.scorecard(pdo=20, base_score=600)
# → Industry-standard credit scoring
```

### B. Risk Scoring Engine (WOE/IV/PSI)

```python
# Weight of Evidence & Information Value
woe_iv = ar.compute_woe_iv(feature="credit_utilization", target="default")
print(f"IV: {woe_iv['iv']:.3f}")  # Predictive power
print(woe_iv['woe_table'])         # Bin-level WOE

# Population Stability Index
psi = ar.compute_psi(
    baseline_data="train.csv",
    current_data="production_data.csv"
)
print(f"PSI: {psi:.3f}")  # <0.1: stable, >0.25: significant drift

# Characteristic Stability Index
csi = ar.compute_csi(feature="income", current_data="latest.csv")
```

### C. Monitoring & Drift Detection

```python
# Continuous monitoring
monitor = ar.monitor(
    production_data="s3://bucket/prod_scores.parquet",
    baseline="train.csv",
    alert_threshold=0.2
)

print(monitor.summary())
# → PSI per feature
# → Score distribution shift
# → Prediction drift
# → Retrain recommendations
```

### D. Explainability (SHAP + Custom)

```python
# Global explainability
ar.explain_global()
# → Top features driving risk
# → SHAP summary plots

# Local explainability (per-record)
explanation = ar.explain_record(customer_id=12345)
print(explanation.reason_codes)
# → "High credit utilization (+45 pts)"
# → "Recent late payments (+30 pts)"
```

### E. Deployment to Azure

```python
# One-command deployment
endpoint = ar.deploy(
    provider="azure_ml",
    workspace="RiskWS",
    resource_group="risk-rg",
    compute_type="aks",  # or "aci" for quick tests
    instance_count=3
)

print(f"Endpoint: {endpoint.scoring_uri}")
print(f"Key: {endpoint.primary_key}")

# Score new data via REST API
scores = endpoint.score(new_customers_df)
```

### F. Backtesting (Trading Mode)

```python
# Time-series walk-forward validation
backtest = ar.backtest(
    data="trading_signals.csv",
    strategy="long_short",
    walk_forward_windows=12,
    refit_frequency="monthly"
)

print(backtest.sharpe_ratio)
print(backtest.max_drawdown)
print(backtest.cumulative_returns)
```

### G. Auto-Reporting

```python
# Generate comprehensive reports
ar.report(
    output="risk_report.html",
    include=[
        "data_profile",
        "woe_iv_tables",
        "model_performance",
        "psi_monitoring",
        "shap_explanations",
        "scorecard",
        "recommendations"
    ]
)

# PDF for regulators
ar.report(output="regulatory_report.pdf", template="basel")
```
