qualia_plugin_snn.datamodel.EventDataModel module

Provide data structures for event-based data processing.

class qualia_plugin_snn.datamodel.EventDataModel.EventDataInfoRecord[source]

Bases: record

Container for begin and end index of event sample.

begin: int64
end: int64
class qualia_plugin_snn.datamodel.EventDataModel.EventData[source]

Bases: RawData

Dataset partition with events as x data.

x: recarray[Any, Any]
class qualia_plugin_snn.datamodel.EventDataModel.EventDataChunks[source]

Bases: RawDataChunks

Dataset partition with events as x data.

chunks: Generator[EventData]
classmethod import_data(path: Path) → EventData | None[source]

Load preprocessed dataset from files.

data.npy, labels.npy and info.npy are loaded from the provided folder as memory-mapped NumPy arrays. The returned array is of type :class:EventData since data is loaded from single files and not by chunks.

Parameters:

path (Path) – Location of the preprocessed data folder

Returns:

:class:EventData object with x, y and info pointing to memory-mapped arrays

Return type:

EventData | None

class qualia_plugin_snn.datamodel.EventDataModel.EventDataSets[source]

Bases: Sets[EventData]

Container for event-based dataset partitions.

class qualia_plugin_snn.datamodel.EventDataModel.EventDataModel[source]

Bases: DataModel[EventData, T]

Container for event-based data model.

sets: Sets[EventData]
__init__(name: str, h: int, w: int, sets: Sets[EventData] | None = None) → None[source]

Instantiate the event-based dataset partitions container.

Parameters:

  • sets (Sets[EventData] | None) – Collection of dataset partitions

  • name (str) – Dataset name

  • h (int) – Maximum y coordinate in data

  • w (int) – Maximum x coordinate in data

Return type:

None

h: int

Maximum y coordinate in data

w: int

Maximum x coordinate in data

Parameters:
Return type:

EventDataModel

class qualia_plugin_snn.datamodel.EventDataModel.EventDataChunksSets[source]

Bases: Sets[EventDataChunks]

Container for event-based dataset partitions.

class qualia_plugin_snn.datamodel.EventDataModel.EventDataChunksModel[source]

Bases: DataModel[EventDataChunks, EventData]

Container for event-based data model.

sets: Sets[EventDataChunks]
__init__(name: str, h: int, w: int, sets: Sets[EventDataChunks] | None = None) → None[source]

Instantiate the event-based dataset partitions container.

Parameters:

  • sets (Sets[EventDataChunks] | None) – Collection of dataset partitions

  • name (str) – Dataset name

  • h (int) – Maximum y coordinate in data

  • w (int) – Maximum x coordinate in data

Return type:

None

h: int

Maximum y coordinate in data

w: int

Maximum x coordinate in data
