Application core

An application core is a utility class to handle all “business logic” for application. It handles communication between dcase_framework.datasets.Dataset(), dcase_framework.features.FeatureExtractor(), dcase_framework.features.FeatureNormalizer(), and dcase_framework.learners.LearnerContainer() classes.

Usage examples:

params = ParameterContainer(filename='parameters.yaml').load().process()

app = AcousticSceneClassificationAppCore(name='Test system',
                                         params=params,
                                         setup_label='Development setup'
                                         )
# Show all datasets available
app.show_dataset_list()

# Show parameters
app.show_parameters()

# Initialize application
app.initialize()

# Extract features
app.feature_extraction()

# Normalize features
app.feature_normalization()

# Train system
app.system_training()

# Test system
app.system_testing()

# Evaluate system
app.system_evaluation()
