🚀 Usage

Generate Calibration Dataset

cargo run -p ml --example generate_calibration_dataset

Run Tests

# All calibration tests
cargo test -p ml --test calibration_dataset_test

# Unit tests only
cargo test -p ml --lib data_loaders::calibration

Programmatic Usage

use ml::data_loaders::calibration::{generate_calibration_dataset, load_calibration_dataset};

// Generate
let dataset = generate_calibration_dataset(
    "test_data/real/databento/ES.FUT_ohlcv-1m_2024-01-02.dbn",
    1000,
    "ES.FUT"
).await?;

// Load
let loaded = load_calibration_dataset("ml/calibration/es_fut_calibration.json").await?;

// Access statistics
for stats in &loaded.feature_stats {
    println!("{}: min={:.4}, max={:.4}", stats.name, stats.min, stats.max);
}

🎯 Integration Points

TFT Quantization

let calibration = load_calibration_dataset("ml/calibration/es_fut_calibration.json").await?;

// Use min/max for INT8 quantization
for stats in &calibration.feature_stats {
    let scale = (stats.max - stats.min) / 255.0;
    let zero_point = -stats.min / scale;
    // Apply quantization...
}

Multi-Symbol Calibration

// Generate for multiple symbols
for symbol in ["ES.FUT", "NQ.FUT", "ZN.FUT", "6E.FUT"] {
    let dataset = generate_calibration_dataset(
        format!("test_data/real/databento/{}_ohlcv-1m_2024-01-02.dbn", symbol),
        1000,
        symbol
    ).await?;
    
    save_calibration_dataset(
        &dataset,
        format!("ml/calibration/{}_calibration.json", symbol.to_lowercase())
    ).await?;
}
