public interface ExampleTransformer extends com.oracle.labs.mlrg.olcut.config.Configurable, com.oracle.labs.mlrg.olcut.provenance.Provenancable<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>, Serializable
Transforms a SparseVector, extracting the features from it as a OnnxTensor.

This usually densifies the example, so can be a lot larger than the input example.

N.B. ONNX support is experimental, and may change without a major version bump.

      ai.onnxruntime.OnnxTensor transform(ai.onnxruntime.OrtEnvironment env, SparseVector vector) throws ai.onnxruntime.OrtException
      Converts a SparseVector representing the features into a OnnxTensor.

      It generates it as a single example minibatch.

      Parameters:
      env - The OrtEnvironment to create the tensor in.
      vector - The features to convert.
      Returns:
      A dense OnnxTensor representing this vector.
      Throws:
      ai.onnxruntime.OrtException - if the transformation failed.
