TrustedFilter.JsonMl.ModelKit

Build an ML model for the TrustedFilter json-ml-relay container in one call. The library trains a calibrated text classifier from your own valid/invalid message samples, verifies it satisfies the relay's model contract, and exports the ML.NET .zip the container loads at startup.

One command

using TrustedFilter.JsonMl.ModelKit;

var result = MlModelBuilder.BuildAndExport(
    validDirectory:   "samples/valid",     // files of messages the relay should PASS, one per line
    invalidDirectory: "samples/invalid",   // files of messages the relay should BLOCK, one per line
    new ModelBuildOptions { OutputPath = "models/custom-model.zip" });

Console.WriteLine($"Model: {result.ModelPath}");
Console.WriteLine($"AUC {result.Auc:F4}, suggested Relay:Ml:Threshold {result.SuggestedThreshold:F2}");

An overload accepts IEnumerable<string> collections instead of directories.

Preparing samples

  • One message per line, formatted exactly as it will arrive on the wire (compact single-line JSON — the relay scores raw bytes, so pretty-printed training data produces a model that fails on real traffic).
  • Roughly one invalid sample per valid one. Good negatives decide the model's sharpness: mix near-misses of your format (missing/typo'd keys), other valid JSON envelopes, and garbage.

Reading the result

MinPositiveProbability and MaxNegativeProbability bound the usable threshold: any Relay:Ml:Threshold between them separates the classes cleanly on the held-out data, and SuggestedThreshold is their midpoint. A narrow or inverted gap means the classes overlap — improve the samples rather than shipping the model.

Deploying the model
