VectorNorm

Compute a norm of the vectors represented by the given axis.

This node interprets all values along the given axis as a vector, and returns its norm. If the data has more axes, e.g., channels, then the vector length is taken separately for each channel/etc of these axes. The chosen axis will be replaced by a one-element feature axis, unless drop_axis is set. If the data is an array and no numeric axis was specified, the axis defaults to -1 (i.e., the last axis of the data). More Info... Version 1.0.0

Ports/Properties

data

Data to process.

  • verbose name: Data
  • default value: None
  • port type: DataPort
  • value type: AnyNumeric (can be None)
  • data direction: INOUT

axis

Axis along which to take the statistic. This axis will drop out of the data and be replaced by a dummy one-element axis (of type feature). You may specify an axis with its label (i.e., space.mylabel) or in the case of incoming data that is an array instead of a Packet, the index of the axis.

  • verbose name: Act Along Axis
  • default value: space
  • port type: ComboPort
  • value type: str (can be None)

ord

Order of the norm. The default is 2, which corresponds to the Euclidean norm or vector length. Other values are 1 (l1 norm aka Manhattan distance), 0 (number of nonzeros), inf (maximum value), and fractional p-norms for p >= 1.

  • verbose name: Order Of Norm
  • default value: 2
  • port type: FloatPort
  • value type: float (can be None)

drop_axis

Drop the axis from the data.

  • verbose name: Drop Axis
  • default value: False
  • port type: BoolPort
  • value type: bool (can be None)

set_breakpoint

Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.

  • verbose name: Set Breakpoint (Debug Only)
  • default value: False
  • port type: BoolPort
  • value type: bool (can be None)

metadata

User-definable meta-data associated with the node. Usually reserved for technical purposes.

  • verbose name: Metadata
  • default value: {}
  • port type: DictPort
  • value type: dict (can be None)
