nil_sink

Module: missions.nodes.sink.nil_sink

Store only meta data of dataset

This is useful to save disk space in scenarios, where only the output of any preceding node is desired, and where there is no need to save the whole data set again.

Class Summary

NilSinkNode(\*\*kwargs) Store only meta information and perform training and testing
OnlyTrainSinkNode(\*\*kwargs) Store only meta information and perform training but not testing

Classes

NilSinkNode

class pySPACE.missions.nodes.sink.nil_sink.NilSinkNode(**kwargs)[source]

Bases: pySPACE.missions.nodes.sink.time_series_sink.TimeSeriesSinkNode

Store only meta information and perform training and testing

The node inherits from TimeSeriesSinkNode, but instead of collecting the data, this node passes a DummyDataset.

Parameters

POSSIBLE NODE NAMES:
 
  • NilSink
  • NilSinkNode
  • Nil_Sink
POSSIBLE INPUT TYPES:
 
  • TimeSeries
  • FeatureVector
  • PredictionVector

Class Components Summary

get_result_dataset() Return the empty dummy collection
input_types
process_current_split() Request the data from the input node and count splits.
input_types = ['TimeSeries', 'FeatureVector', 'PredictionVector']
__init__(**kwargs)[source]
process_current_split()[source]

Request the data from the input node and count splits.

get_result_dataset()[source]

Return the empty dummy collection

OnlyTrainSinkNode

class pySPACE.missions.nodes.sink.nil_sink.OnlyTrainSinkNode(**kwargs)[source]

Bases: pySPACE.missions.nodes.sink.nil_sink.NilSinkNode

Store only meta information and perform training but not testing

The node performs only training on the node chain, so that the test procedure can be performed manually, e.g. for debug and testing reasons.

The node is very similar to the NilSinkNode.

Parameters

POSSIBLE INPUT TYPES:
 
  • TimeSeries

  • PredictionVector

Class Components Summary

process_current_split() Request the data from the input node and count splits
request_data_for_testing() Request data for testing, just call the predecessors method
__init__(**kwargs)[source]
process_current_split()[source]

Request the data from the input node and count splits

request_data_for_testing()[source]

Request data for testing, just call the predecessors method

This is possible, since this node does not process any data and slightly shortens processing time.
