Abstract Value Members

  1. abstract def feature(index: Int)(implicit ev: TensorNumeric[T]): Tensor[T]

    Get feature tensor for given index

    Get feature tensor for given index

    index

    index of specific sample

  2. abstract def feature()(implicit ev: TensorNumeric[T]): Tensor[T]

    Get feature tensor, for one feature Sample only.

    Get feature tensor, for one feature Sample only. You don't need to override this, because we have add a default implement to throw exception.

    returns

    feature tensor

  3. abstract def featureLength(index: Int): Int

    First dimension length of index-th feature.

    First dimension length of index-th feature. This function could be used to sort samples in DataSet.

    returns

  4. abstract def getData(): Array[T]

    Get data

    Get data

    returns

    data

  5. abstract def getFeatureSize(): Array[Array[Int]]

    Get feature sizes

    Get feature sizes

    returns

    feature sizes

  6. abstract def getLabelSize(): Array[Array[Int]]

    Get label sizes

    Get label sizes

    returns

    label sizes

  7. abstract def label(index: Int)(implicit ev: TensorNumeric[T]): Tensor[T]

    Get label tensor for given index

    Get label tensor for given index

    index

    index of specific sample

  8. abstract def label()(implicit ev: TensorNumeric[T]): Tensor[T]

    Get label tensor, for one label Sample only.

    Get label tensor, for one label Sample only. You don't need to override this, because we have add a default implement to throw exception.

    returns

    label tensor

  9. abstract def labelLength(index: Int): Int

    First dimension length of index-th label.

    First dimension length of index-th label. This function could be used to find the longest label.

    returns

  10. abstract def numFeature(): Int

    Number of tensors in feature

    Number of tensors in feature

    returns

    number of tensors in feature

  11. abstract def numLabel(): Int

    Number of tensors in label
