<p><b>Title: </b><b>Multi-view Relationships for Analytics and
Inference</b></p>
<p>Abstract:</p>
<p>An interesting area of machine learning is methods for multi-view
data, relational data whose features have been partitioned.
Multi-view learning exploits relationships between views, giving
it certain advantages over traditional single-view techniques,
which may struggle to find these relationships or only learn them
implicitly. These relationships are often especially salient in
understanding the data or performing prediction. This work
explores an underutilized approach in multi-view learning: to
focus on multi-view relationships---the variables that govern
relations between views---themselves as units of analysis. We
investigate how this approach impacts analytics and inference in
ways that standard multi-view and single-view learning cannot. We
hypothesize that by ignoring relations between views or factoring
them in only indirectly, standard approaches risk overlooking key
structure. Accordingly, our goal is to investigate the extent
multi-view relationships can be characterized and employed as
units of analysis in descriptive analytics and inference. We
present novel methods to do so, either using domain knowledge or
by learning from data, which reveal structure that alternative
methods do not or have competitive performance with the state of
the art. Empirical results are presented in several application
domains. First, we use domain knowledge to assume a known form for
multi-view relationships in the task of gamma source detection. We
aggregate the views by filtering their inferences collectively to
perform classification. Second, we assume multi-view relationships
are linear and learn them from data in a different approach toward
gamma source detection. Our method detects anomalies when these
relationships are disrupted. Third, we relax the assumption of
linearity and propose a novel clustering method that finds
cluster-wise linear relationships. This method discovers
explanatory structure in a medical problem. Fourth, we extend this
method to classification and demonstrate its superior performance
on a load monitoring problem.<br>
