New Features

  • New API for exporting models to Onnx. (#5544). A new API has been added to Onnx converter to specify the output columns you care about. This will export a smaller and more performant model in many cases.

Enhancements

  • Perf improvement for TopK Accuracy and return all topK in Classification Evaluator (#5395) (Thank you @jasallen)
  • Update OnnxRuntime to 1.6 (#5529)
  • Updated tensorflow.net to 0.20.0 (#5404)
  • Added in DcgTruncationLevel to AutoML api and increased default level to 10 (#5433)

Bug Fixes

  • AutoML.NET specific fixes.
    • Fixed AutoFitMaxExperimentTimeTest (#5506)
    • Fixed code generator tests failure (#5520)
