Use the initialized Arize client to call arize.log() with a predicted label, predicted actual, their feature inputs, their shap values, and a corresponding prediction id. Once records are sent to Arize’s platform, you’ll be able to visualize and analyze data holistically or within aggregated slices. arize.log() returns a Response. You can await on the Response to complete to ensure successful delivery of records. When logging a prediction for the first time for a new model, we classify the model in the Arize platform based on the data type of the prediction.

API Arguments

ArgumentType(s)DescriptionRequired
modelIdStringCostumer provided unique identifier for a given model.Y
modelVersionStringUsed to group together a subset of predictions and actuals for a given model_id. If null is passes, a prediction will only be associated with a model id with no version.Y
predictionIdStringUnique string identifier for specific label. Must match a previously sent Prediction record.Y
featuresMap<String, ?>Where value can be oneOf: String, int, long, short, double, float, boolean, List<String>Map containing human readable and debuggable model features. Map keys must be String and values one of: String, int, long, short, double, float, boolean, List<String>Optional
embeddingFeaturesMap<String, Embedding>Map containing human readable and debuggable model embedding features. Map keys must be String and values Embedding
tagsMap<String, ?> Where value can be oneOf: String, int, long, short, double, float, boolean, List<String>Map containing human readable and debuggable model features. Map keys must be String and values one of: String, int, long, short, double, float, boolean, List<String>Optional
predictionLabelString, boolean, int, long, short, float, doubleThe predicted label for a given model input (associated via predictionId).Optional
actualLabelString, boolean, int, long, short, float, doubleThe actual label for a given model input (associated via predictionId)Optional
shapValuesMap<String, Double>Map keys must be String and match the names of the features used in the prediction; values must be Double.Optional
predictionTimestamplongIf long representing Unix epoch time in seconds, set overwrite the timestamp for prediction.If null, default to current timestamp.Important: Future and Historical predictions are supported up to 1 year from current wall clock time.Optional

Sample Code - Sending in Numeric Sequences for Ranking Models

The following code snippet highlights the use of the ScoredCategorical constructor for including a numeric sequence in the actualScoreLabel 
import com.arize.ArizeClient.ScoredCategorical;

Map<String, String> features = new HashMap<>();
features.put("key", "value");

// Score Categorical Label
ScoredCategorical predictionScoreLabel = new ScoredCategorical("Categorical Label", 20.21);
ScoredCategorical actualScoreLabel = new ScoredCategorical("relevant", 4.13, Arrays.asList(0.12, 0.23, 0.34))

Response response = client.log("modelId", "modelVersion", "predictionId", features, predictionScoreLabel, actualScoreLabel, null, 0);

// This is a blocking call similar to future.get()
asyncResponse.resolve();
