  Intelligent robots frequently need to explore the objects in their working
  environments. Modern sensors have enabled robots to learn object properties
  via perception of multiple modalities. However, object exploration in the
  real world poses a challenging trade-off between information gains and
  exploration action costs. Mixed observability Markov decision process (MOMDP)
  is a framework for planning under uncertainty, while accounting for both
  fully and partially observable components of the state. Robot perception
  frequently has to face such mixed observability. This work enables a robot
  equipped with an arm to dynamically construct query-oriented MOMDPs for
  multi-modal predicate identification (MPI) of objects. The robot's behavioral
  policy is learned from two datasets collected using real robots. Our approach
  enables a robot to explore object properties in a way that is significantly
  faster while improving accuracies in comparison to existing methods that rely
  on hand-coded exploration strategies.
