Possible error types when classifying with a [SVMCore].

Variants

AttributesUnordered

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].

Fields of AttributesUnordered

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.

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.

ParsingError(String)

Wrapper for internal parsing error when unifiying error handling.
