Uses of BaseTransform in org.datavec.api.transform.ndarray

Subclasses of BaseTransform in org.datavec.api.transform.ndarray

Modifier and Type	Class and Description
class	NDArrayMathFunctionTransform A simple transform to do common mathematical operations, such as sin(x), ceil(x), etc. Operations are performed element-wise on each value in the INDArray; operations are specified by MathFunction
class	NDArrayScalarOpTransform Perform an NDArray/scalar element wise operation, such as X.addi(scalar).

Modifier and Type	Class and Description
class	CategoricalToIntegerTransform Created by Alex on 4/03/2016.
class	CategoricalToOneHotTransform Created by Alex on 4/03/2016.
class	IntegerToCategoricalTransform Convert an integer column to a categorical column, using a provided Map<Integer,String>
class	PivotTransform Pivot transform operates on two columns: - a categorical column that operates as a key, and - Another column that contains a value Essentially, Pivot transform takes keyvalue pairs and breaks them out into separate columns.
class	StringToCategoricalTransform Convert a String column to a categorical column

Uses of BaseTransform in org.datavec.api.transform.transform.column

Uses of BaseTransform in org.datavec.api.transform.transform.doubletransform

Subclasses of BaseTransform in org.datavec.api.transform.transform.doubletransform

Modifier and Type	Class and Description
class	BaseDoubleTransform
class	ConvertToDouble Convert any value to an Double
class	DoubleMathFunctionTransform A simple transform to do common mathematical operations, such as sin(x), ceil(x), etc. Operations are specified by MathFunction
class	DoubleMathOpTransform Double mathematical operation. This is an in-place operation of the double column value and a double scalar.
class	Log2Normalizer Normalize by taking scale * log2((in-columnMin)/(mean-columnMin) + 1) Maps values in range (columnMin to infinity) to (0 to infinity) Most suitable for values with a geometric/negative exponential type distribution.
class	MinMaxNormalizer Normalizer to map (min to max) -> (newMin-to newMax) linearly.
class	StandardizeNormalizer Normalize using (x-mean)/stdev.
class	SubtractMeanNormalizer Normalize by substracting the mean
