Measurements of how well the MLModel performed on known observations. One of the following metrics is returned, based on the type of the MLModel :

  • BinaryAUC: The binary MLModel uses the Area Under the Curve (AUC) technique to measure performance.

  • RegressionRMSE: The regression MLModel uses the Root Mean Square Error (RMSE) technique to measure performance. RMSE measures the difference between predicted and actual values for a single variable.

  • MulticlassAvgFScore: The multiclass MLModel uses the F1 score technique to measure performance.

For more information about performance metrics, please see the Amazon Machine Learning Developer Guide .

 
 public class PerformanceMetrics implements SerializableCloneable {
 
     private java.util.Map<String,Stringproperties;

    
Returns the value of the Properties property for this object.

Returns:
The value of the Properties property for this object.
 
     public java.util.Map<String,StringgetProperties() {
         
         if ( == null) {

Sets the value of the Properties property for this object.

Parameters:
properties The new value for the Properties property for this object.
 
     public void setProperties(java.util.Map<String,Stringproperties) {
         this. = properties;
     }
    
    
Sets the value of the Properties property for this object.

Returns a reference to this object so that method calls can be chained together.

Parameters:
properties The new value for the Properties property for this object.
Returns:
A reference to this updated object so that method calls can be chained together.
 
     public PerformanceMetrics withProperties(java.util.Map<String,Stringproperties) {
         setProperties(properties);
         return this;
     }

    
Sets the value of the Properties property for this object.

The method adds a new key-value pair into Properties parameter, and returns a reference to this object so that method calls can be chained together.

Parameters:
key The key of the entry to be added into Properties.
value The corresponding value of the entry to be added into Properties.
  public PerformanceMetrics addPropertiesEntry(String keyString value) {
    if (null == this.) {
      this. = new java.util.HashMap<String,String>();
    }
    if (this..containsKey(key))
      throw new IllegalArgumentException("Duplicated keys (" + key.toString() + ") are provided.");
    this..put(keyvalue);
    return this;
  }

  
Removes all the entries added into Properties.

Returns a reference to this object so that method calls can be chained together.

    this. = null;
    return this;
  }
  
    
Returns a string representation of this object; useful for testing and debugging.

Returns:
A string representation of this object.
