Possible error types when classifying with one of the SVMs.

Fields

index: u32

The index process that was not a direct successor of the previous index. Can be used for easier debugging the model file.

value: f32

The value of the given index. Can be used for debugging in conjunction with index.

last_index: u32

The last index processed. If everything were alright, then index should equal last_index + 1.

This can be emitted when creating a SVM from a ModelFile. For models generated by libSVM’s svm-train, the most common reason this occurs is skipping attributes. All attributes must be in sequential order 0, 1, 2, …, n. If they are not, this error will be emitted. For more details see the documentation provided in ModelFile.

NoProbabilities

This error can be emitted by Predict::predict_probability in case the model loaded by ModelFile was not trained with probability estimates (svm-train -b 1).

IterationsExceeded

Can be emitted by Predict::predict_probability when predicting probabilities and the internal iteration limit was exceeded.

NoGamma

If the model does not have a gamma set this error may be raised.

NoCoef0

If the model does not have a coef0 set this error may be raised.

NoDegree

If the model does not have a degree set this error may be raised.

Parsing(String)

Wrapper for internal parsing error when unifiying error handling.

MissingRequiredAttribute

A required attribute was not found.
