CSV format
Edge Impulse requires CSV data to be stored in a particular format. You’ll need to create one CSV file per sample (e.g. a machine with a fault state). The first row should be a header describing the sensor axes, and each row should be a single reading at a particular time. For multi-axis, time-series data, the first column name must betimestamp
in millisecond format. It should have constant intervals between lines (ie: 16 below), the data ingestion service will infer the sampling frequency from the intervals. For example, this is data from an accelerometer:
CSV filename
If you prefix the file name with the name of the label, the uploader will automatically assign the right labels to your data. The prefix should end with a period before the sample name in the following format:faultstate1.sample0.csv
will tell the Studio that the containing data should have the label faultstate1
