Method Detail

isValidValue

public boolean isValidValue(org.nd4j.linalg.api.ndarray.INDArray value)

Validates whether a INDArray conforms to this time series. An INDArray confirms to this value, if its rank is 1 and its length equals the length of this time series.

Specified by:

isValidValue in interface IAttributeType<org.nd4j.linalg.api.ndarray.INDArray>

Parameters:

value - The value to validated.

Returns:

Returns true if the given value conforms

buildAttributeValue

public IAttributeValue<org.nd4j.linalg.api.ndarray.INDArray> buildAttributeValue(java.lang.Object value)

Description copied from interface: IAttributeType

Casts the value to the respective type and returns an attribute value with the creating attribute type as the referenced type.

Specified by:

buildAttributeValue in interface IAttributeType<org.nd4j.linalg.api.ndarray.INDArray>

Parameters:

value - The value of the attribute.

Returns:

An attribute value object holding the value of the attribute and referring to this attribute type.

buildAttributeValue

public IAttributeValue<org.nd4j.linalg.api.ndarray.INDArray> buildAttributeValue(java.lang.String stringDescription)

Description copied from interface: IAttributeType

Builds an attribute value object from a string description. The attribute value references this attribute type.

Specified by:

buildAttributeValue in interface IAttributeType<org.nd4j.linalg.api.ndarray.INDArray>

Parameters:

stringDescription - A String-format description of the attribute's value.

Returns:

The attribute value object holding an attribute value interpreting the string description and referring to this attribute type.

getLength

public int getLength()

Get the length of this time series attribute type.

Returns:

The length respec. the number of datapoints of this time series attribute.

setLength

public void setLength(int length)
