configs |
Mapping configuration for this SliceSpec. The key is the name of the feature. By default, the key will be prefixed by "instance" as a dictionary prefix for Vertex Batch Predictions output format. |
SliceConfig
Specification message containing the config for this SliceSpec. When kind
is selected as value
and/or range
, only a single slice will be computed. When allValues
is present, a separate slice will be computed for each possible label/value for the corresponding key in config
. Examples, with feature zip_code with values 12345, 23334, 88888 and feature country with values "US", "Canada", "Mexico" in the dataset:
Example 1:
{
"zip_code": { "value": { "floatValue": 12345.0 } }
}
A single slice for any data with zip_code 12345 in the dataset.
Example 2:
{
"zip_code": { "range": { "low": 12345, "high": 20000 } }
}
A single slice containing data where the zip_codes between 12345 and 20000 For this example, data with the zip_code of 12345 will be in this slice.
Example 3:
{
"zip_code": { "range": { "low": 10000, "high": 20000 } },
"country": { "value": { "stringValue": "US" } }
}
A single slice containing data where the zip_codes between 10000 and 20000 has the country "US". For this example, data with the zip_code of 12345 and country "US" will be in this slice.
Example 4:
{ "country": {"allValues": { "value": true } } }
Three slices are computed, one for each unique country in the dataset.
Example 5:
{
"country": { "allValues": { "value": true } },
"zip_code": { "value": { "floatValue": 12345.0 } }
}
Three slices are computed, one for each unique country in the dataset where the zip_code is also 12345. For this example, data with zip_code 12345 and country "US" will be in one slice, zip_code 12345 and country "Canada" in another slice, and zip_code 12345 and country "Mexico" in another slice, totaling 3 slices.

Union field
|
|
value |
A unique specific value for a given feature. Example: |
range |
A range of values for a numerical feature. Example: |
allValues |
If allValues is set to true, then all possible labels of the keyed feature will have another slice computed. Example: |
Value
Single value that supports strings and floats.
