ee.ConfusionMatrix.array

  • Thearray() method returns a confusion matrix as anArray.

  • Thearray() method is called on aConfusionMatrix object.

  • The examples demonstrate how to create aConfusionMatrix and then retrieve its array representation in both JavaScript and Python.

 Returns a confusion matrix as an Array.

UsageReturns
ConfusionMatrix.array()Array
ArgumentTypeDetails
this:confusionMatrixConfusionMatrix

Examples

Code Editor (JavaScript)

// Construct a confusion matrix from an array (rows are actual values,// columns are predicted values). We construct a confusion matrix here for// brevity and clear visualization, in most applications the confusion matrix// will be generated from ee.Classifier.confusionMatrix.vararray=ee.Array([[32,0,0,0,1,0],[0,5,0,0,1,0],[0,0,1,3,0,0],[0,1,4,26,8,0],[0,0,0,7,15,0],[0,0,0,1,0,5]]);varconfusionMatrix=ee.ConfusionMatrix(array);print("ee.ConfusionMatrix",confusionMatrix);print("ee.ConfusionMatrix as ee.Array",confusionMatrix.array());
