Data Formats for k-NN Training Input

All Amazon SageMaker built-in algorithms adhere to the common input training formats described in Common Data Formats - Training. This topic contains a list of the available input formats for the SageMaker k-nearest-neighbor algorithm.

CSV Data Format

content-type: text/csv; label_size=1

4,1.2,1.3,9.6,20.3

The first label_size columns are interpreted as the label vector for that row.

RECORDIO Data Format

content-type: application/x-recordio-protobuf

[
    Record = {
        features = {
            'values': {
                values: [1.2, 1.3, 9.6, 20.3]  # float32
            }
        },
        label = {
            'values': {
                values: [4]  # float32
            }
        }
    }
]
