ee.ConfusionMatrix(array, order) | ConfusionMatrix |
Argumento | Tipo | Detalles |
---|---|---|
array | Objeto | Es un array cuadrado de números enteros que representa la matriz de confusión. Ten en cuenta que, a diferencia del constructor ee.Array, este argumento no puede tomar una lista. |
order | Lista, valor predeterminado: null | Tamaño y orden de las filas y columnas para matrices no contiguas o no basadas en cero. |
