# Use a simple sequence example
dataset <- examples_motifs$simple
head(dataset)

# Configure discord discovery via SAX
model <- hdis_sax(26, 3, 3)

# Fit the model
model <- fit(model, dataset$serie)

# Run detection
detection <- detect(model, dataset$serie)

# Show detected discords
print(detection[(detection$event),])
