DelayEmbedding¶
Perform delay embedding of the given signal.
This will add a new axis of type LagAxis to the data, which has n copies of the signal, each delayed by the respective n'th lag in samples. This axis can subsequently be folded into other axes using the Fold Into Axis node. One use of this filter is to convert filters that regularly combine multiple channels into filters that combine both channels and time points (i.e., to turn spatial filters into spatio-temporal filters). An example is to turn Common Spatial Patterns (CSP) into Common Spatio-Spectral Patterns (CSSP) by preceding CSP with a delay embedding node. Version 1.0.0
Ports/Properties¶
data¶
Data to process.
- verbose name: Data
- default value: None
- port type: DataPort
- value type: Packet (can be None)
- data direction: INOUT
axis¶
Axis along which to compute the delay embedding.
- verbose name: Delay-Embed Along Axis
- default value: time
- port type: ComboPort
- value type: str (can be None)
lags¶
Lags to use. This is a list of offsets, in samples, where positive values refer to past samples. Negative values can be used, but not on streaming data.
- verbose name: Lags
- default value: [0, 1, 2, 3]
- port type: ListPort
- value type: list (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)
