Title: Learning Complex Robotic Skills via Conditional Neural Movement
Primitives
Abstract: Predicting the consequences of one's own actions is an
important requirement for safe human-robot collaboration and its
application to personal robotics. Neurophysiological and behavioral
data suggest that the human brain benefits from internal forward
models that continuously predict the outcomes of the generated motor
commands for trajectory planning, movement control, and multi-step
planning. In this talk, I will present our recent Learning from
Demonstration framework [1] that is based on Conditioned Neural
Processes. CNMPs extract the prior knowledge directly from the
training data by sampling observations from it, and use it to predict
a conditional distribution over any other target points. CNMPs
specifically learn complex temporal multi-modal sensorimotor relations
in connection with external parameters and goals; produce movement
trajectories in joint or task space; and execute these trajectories
through a high-level feedback control loop. Conditioned with an
external goal that is encoded in the sensorimotor space of the robot,
predicted sensorimotor trajectory that is expected to be observed
during the successful execution of the task is generated by the CNMP,
and the corresponding motor commands are executed. After presenting
the basic CNMP framework, I will talk about how to form flexible
skills combining Learning from Demonstration and Reinforcement
Learning via Representation Sharing [2], and the deep modality
blending networks (DMBN) [3], which creates a common latent space from
multi-modal experience of a robot by blending multi-modal signals with
a stochastic weighting mechanism.
