Class ScoringTimePerRow

java.lang.Object

water.Iced<ScoringTimePerRow>

ai.h2o.automl.leaderboard.ScoringTimePerRow

All Implemented Interfaces:

LeaderboardCell<java.lang.Double,ScoringTimePerRow>, java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, water.Freezable<ScoringTimePerRow>

public class ScoringTimePerRow
extends water.Iced<ScoringTimePerRow>
implements LeaderboardCell<java.lang.Double,ScoringTimePerRow>

A cell computing lazily the average time needed to score a single row with the model. If there is a leaderboard frame available, this average time will be computed by scoring the entire frame. Otherwise, the training frame will be used.

Method Detail

getColumn

public LeaderboardColumn getColumn()

Specified by:

getColumn in interface LeaderboardCell<java.lang.Double,ScoringTimePerRow>

Returns:

the column to which this cell belongs.

getModelId

public water.Key<hex.Model> getModelId()

Specified by:

getModelId in interface LeaderboardCell<java.lang.Double,ScoringTimePerRow>

Returns:

the row index of this cell.

getValue

public java.lang.Double getValue()

Description copied from interface: LeaderboardCell

gets the current value of the cell. If the value is not immediately available, this should return null, so that the client code can decide to call LeaderboardCell.fetch(). This is an accessor, it is safe to call LeaderboardCell.getValue() multiple times without triggering any side effect.

Specified by:

getValue in interface LeaderboardCell<java.lang.Double,ScoringTimePerRow>

Returns:

the current cell value.

setValue

public void setValue(java.lang.Double value)

Description copied from interface: LeaderboardCell

sets the cell value. This can be useful for optimization, when the value is expensive to compute and available at some point during the automl run.

Specified by:

setValue in interface LeaderboardCell<java.lang.Double,ScoringTimePerRow>

isNA

public boolean isNA()

Specified by:

isNA in interface LeaderboardCell<java.lang.Double,ScoringTimePerRow>

Returns:

true id the value is not available

fetch

public java.lang.Double fetch()

Description copied from interface: LeaderboardCell

Fetch the value if necessary: this may be a long running task.

Specified by:

fetch in interface LeaderboardCell<java.lang.Double,ScoringTimePerRow>

Returns:
