Field Details

expectedCount

protected long expectedCount

The number of expected events observed.

anomalyCount

protected long anomalyCount

The number of anomalous events observed.

unknownCount

protected int unknownCount

The number of unknown events observed (i.e., those without labels).

Constructor Details

AnomalyInfo

protected AnomalyInfo()

Constructs a new empty anomaly info.

AnomalyInfo

protected AnomalyInfo(AnomalyInfo other)

Copies the supplied anomaly info.

Parameters:

other - The info to copy.

Method Details

getUnknownCount

public int getUnknownCount()

Description copied from interface: OutputInfo

Returns the number of unknown Output instances (generated by OutputFactory.getUnknownOutput()) that this OutputInfo has seen.

Specified by:

getUnknownCount in interface OutputInfo<Event>

Returns:

The number of unknown outputs observed.

getAnomalyCount

public long getAnomalyCount()

The number of anomalous events observed.

Returns:

The number of anomalies.

getExpectedCount

public long getExpectedCount()

The number of expected events observed.

Returns:

The number of normal events.

getDomain

public Set<Event> getDomain()

Returns the set of possible Events.

Each event has the default score of Double.NaN.

Specified by:

getDomain in interface OutputInfo<Event>

Returns:

The set of possible events.

getEventCount

public long getEventCount(Event.EventType type)

Gets the count of the supplied EventType.

Parameters:

type - An EventType.

Returns:

A non-negative long.

outputCountsIterable

public Iterable<com.oracle.labs.mlrg.olcut.util.Pair<String,Long>> outputCountsIterable()

Description copied from interface: OutputInfo

An Iterable over the possible outputs and the number of times they were observed.

Provides similar functionality to an iterator over the entrySet of a Map, though this is a copy of the data and immutable.

Specified by:

outputCountsIterable in interface OutputInfo<Event>

Returns:

Lambda wrapping an iterator over Pairs.

size

public int size()

The number of possible event types (i.e., 2).

Specified by:

size in interface OutputInfo<Event>

Returns:

The number of possible event types.

generateImmutableOutputInfo

public ImmutableOutputInfo<Event> generateImmutableOutputInfo()

Description copied from interface: OutputInfo

Generates an ImmutableOutputInfo which has a copy of the data in this OutputInfo, but also has id values and is immutable.

Specified by:

generateImmutableOutputInfo in interface OutputInfo<Event>

Returns:

An immutable copy of this OutputInfo.

generateMutableOutputInfo

public MutableOutputInfo<Event> generateMutableOutputInfo()

Description copied from interface: OutputInfo

Generates a mutable copy of this OutputInfo.

Specified by:

generateMutableOutputInfo in interface OutputInfo<Event>

Returns:

A mutable copy of this OutputInfo.

toReadableString

public String toReadableString()

Description copied from interface: OutputInfo

Generates a String form of this OutputInfo.

This String can contain newlines, tabs and other formatting.

Specified by:

toReadableString in interface OutputInfo<Event>

Returns:

A formatted String representing this OutputInfo.

copy

public abstract AnomalyInfo copy()

Description copied from interface: OutputInfo

Generates a copy of this OutputInfo, including it's mutability.

Specified by:

copy in interface OutputInfo<Event>

Returns:

A copy of the OutputInfo.
