generate_labels_from_dataframe

edgeimpulse.experimental.util.generate_labels_from_dataframe(
		df,
		label_col='label',
		file_name=None
)
Generates structured labels from a DataFrame based on transitions in the specified label column. This function iterates over the rows of a pandas DataFrame and detects changes in the values of a specified label column. It groups consecutive rows with the same label value, and for each group, it returns a dictionary containing the start index, end index, and the label. Optionally, the result can be returned in a dictionary format, compatible with file saving, including the file name. Parameters
  • df
  • label_col=‘label’
  • file_name=None
