Syntax

public class RankingMetrics : IDirectResponseSchema

Properties

AverageRank

Determines the goodness of a ranking by computing the percentile rank from the predicted confidence and dividing it by the original rank.

Declaration

[JsonProperty("averageRank")]
public virtual double? AverageRank { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

ETag

The ETag of the item.

Declaration

public virtual string ETag { get; set; }

Property Value

Type	Description
System.String

MeanAveragePrecision

Calculates a precision per user for all the items by ranking them and then averages all the precisions across all the users.

Declaration

[JsonProperty("meanAveragePrecision")]
public virtual double? MeanAveragePrecision { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

MeanSquaredError

Similar to the mean squared error computed in regression and explicit recommendation models except instead of computing the rating directly, the output from evaluate is computed against a preference which is 1 or 0 depending on if the rating exists or not.

Declaration

[JsonProperty("meanSquaredError")]
public virtual double? MeanSquaredError { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

NormalizedDiscountedCumulativeGain

A metric to determine the goodness of a ranking calculated from the predicted confidence by comparing it to an ideal rank measured by the original ratings.

Declaration

[JsonProperty("normalizedDiscountedCumulativeGain")]
public virtual double? NormalizedDiscountedCumulativeGain { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>
