3.  ML.NET  Fundamentals

Understanding  ML.NET  Architecture

ML.NET  is Microsoft's open-source, cross-platform machine learning framework specifically designed for .NET developers.

Key Components

  
    // Basic ML.NET Pipeline Structure
public class MLNetBasicPipeline
{
    private readonly MLContext _mlContext;
    
    public MLNetBasicPipeline()
    {
        _mlContext = new MLContext(seed: 0);
    }
    
    public ITransformer TrainModel<TData>(IEnumerable<TData> trainingData) 
        where TData : class
    {
        // Load data
        var dataView = _mlContext.Data.LoadFromEnumerable(trainingData);
        
        // Define pipeline
        var pipeline = _mlContext.Transforms
            .Conversion.MapValueToKey("Label")
            .Append(_mlContext.Transforms.Concatenate("Features", 
                nameof(TData.Features)))
            .Append(_mlContext.MulticlassClassification.Trainers
                .SdcaMaximumEntropy("Label", "Features"))
            .Append(_mlContext.Transforms.Conversion.MapKeyToValue("PredictedLabel"));
        
        // Train model
        return pipeline.Fit(dataView);
    }
}

Data Models for Machine Learning

  
    // Real Estate Price Prediction Model
public class RealEstateData
{
    [LoadColumn(0)]
    public float SizeSqFt { get; set; }
    
    [LoadColumn(1)]
    public float Bedrooms { get; set; }
    
    [LoadColumn(2)]
    public float Bathrooms { get; set; }
    
    [LoadColumn(3)]
    public float YearBuilt { get; set; }
    
    [LoadColumn(4)]
    public float LocationScore { get; set; }
    
    [LoadColumn(5)]
    public float Price { get; set; } // Label
}

public class RealEstatePrediction
{
    [ColumnName("Score")]

}
