A sequence set is a collection of data sets. Where each individual data set
is one "unbroken sequence" within the sequence set. This allows individual
observations to occur individually, indicating a break between them.
The sequence set, itself, is a data set, so it can be used with any Encog
trainer. However, not all trainers are aware of sequence sets. Further, some
machine learning methods are unaffected by them. Sequence sets are typically
used with Hidden Markov Models (HMM)'s.
