Interface Summary
*Model*	An interface for introspective models.
*Model.Delta*	A summary of the knowledge learned by a `Model`.
*Model.Prediction*	A summary of the current state predicted by the `Model`.
*SegmentedModel*	An interface for introspective models which participate as part of large, distributed models.
*SegmentedModel.Segment*	A single, tagged portion of the global `Model` state.

Class Summary

Array A sparse array of doubles.

EventCountMsg EventCountMsg is an event that tells you how many times a specified event has been counted by EventCountStage.

EventCountRequestMsg EventCountRequestMsg is an event requesting to know how many times a certain event has been counted by EventCountStage.

EventCountStage EventCountStage watches for events of certain types, and counts them.

HMM Hidden Markov Model: a statistical tool which models a chain of observed variables as the output of a chain of hidden states.

HMM.Delta A HMM.Delta object contains a diff of the sufficient statistics for an HMM.

HMM.Prediction A Prediction object contains an array of states and a matching array of weights.

HMM.Segment A Segment object contains the internal model state associated with a single state.

HMMBuilder A stage which automatically fits a Hidden Markov Model to a monitored event stream.

HMMPredictor A stage which uses a Hidden Markov Model to predict the future of a monitored event stream.

HMMStage A superclass for stages which employ HMMs.

Matrix A sparse array of Arrays.

NetSync A test file used to determine clock skew between machines.

Screen A model that filters a stream of QuickSerializable objects.

SegmentPager A stage which fetches model segments to/from remote carriers.

SegmentPager.Request

SegmentPager.ReverseRequest

TestFileEvent A simple class to signal file operation events.

TraceReader A SandStorm stage which reads trace files and generates events for each trace entry.

Exception Summary

HMMStage.InvalidTypeException An exception thrown when a config file supplies the name of a class or field that does not satisfy type restrictions.

HMMStage.UnsupportedConfigurationException An exception thrown when a config file requests an operation (e.g. emit_predictions) that a particular Builder does not provide.
