MLoop.Extensibility

Optional extensibility API for MLoop - enables code-based customization of AutoML pipeline.

Overview

MLoop.Extensibility provides interfaces for extending MLoop's AutoML capabilities through:

  • Hooks: Execute custom logic at lifecycle points (pre-train, post-train, etc.)
  • Custom Metrics: Optimize for business outcomes instead of generic accuracy

Features

  • ✅ Completely Optional: Works without any extensions
  • ✅ Zero-Overhead: < 1ms impact when not used
  • ✅ Type-Safe: Full C# type system with IDE support
  • ✅ Auto-Discovery: Convention-based discovery from filesystem

Quick Start

Install Package

dotnet add package MLoop.Extensibility

Create a Hook

using MLoop.Extensibility;

public class DataValidationHook : IMLoopHook
{
    public string Name => "Data Validation";

    public async Task<HookResult> ExecuteAsync(HookContext ctx)
    {
        var rowCount = ctx.DataView.Preview().RowView.Length;

        if (rowCount < 100)
        {
            return HookResult.Abort("Need at least 100 rows");
        }

        ctx.Logger.Info($"✅ Validation passed: {rowCount} rows");
        return HookResult.Continue();
    }
}

Create a Custom Metric

using MLoop.Extensibility;

public class ProfitMetric : IMLoopMetric
{
    public string Name => "Expected Profit";
    public bool HigherIsBetter => true;

    public async Task<double> CalculateAsync(MetricContext ctx)
    {
        var metrics = ctx.MLContext.BinaryClassification.Evaluate(ctx.Predictions);

        // Optimize for profit instead of accuracy
        return (metrics.PositiveRecall * 100.0) +  // $100 per True Positive
               (metrics.FalsePositiveRate * -50.0); // -$50 per False Positive
    }
}
