ClassesClassDescriptionTransforms a && b into if(a, b, false) and a || b into if(a, true, b) to avoid computing b if a is false and true respectively.Transforms named references to constant tensors with the rank feature 'constant'.The transformations done on ranking expressions done at config time before passing them on to the Vespa engine for execution.Inlines functions in ranking expressionsTransforms function nodes to reference nodes if a rank profile function shadows a built-in function.Analyzes expression to figure out what inputs it needsReplaces instances of the lightgbm(model-path) pseudofeature with the native Vespa ranking expression implementing the same computation.Recognizes pseudo-functions and creates global-phase normalizersReplaces instances of the onnx(model-path, output) pseudofeature with the native Vespa ranking expression implementing the same computation.Transforms ONNX model features of the forms: onnx(config_name) onnx(config_name).output onnx("path/to/model") onnx("path/to/model").output onnx("path/to/model", "path/to/output") onnx("path/to/model", "unused", "path/to/output") // signature is unused To the format expected by the backend: onnx(config_name).outputExtends the transform context with rank profile informationConvenience feature transforms for inputs to Transformer type models.Replaces instances of the xgboost(model-path) pseudofeature with the native Vespa ranking expression implementing the same computation.
