Introduction to the Special Issue on Machine Learning for Multiple Modalities in Interactive Systems and Robots
This special issue highlights research articles that apply machine learning to robots and other systems that interact with users through more than one modality, such as speech, gestures, and vision. For example, a robot may coordinate its speech with ...
Efficient Interactive Multiclass Learning from Binary Feedback
We introduce a novel algorithm called upper confidence-weighted learning (UCWL) for online multiclass learning from binary feedback (e.g., feedback that indicates whether the prediction was right or wrong). UCWL combines the upper confidence bound (UCB) ...
Interpreting Natural Language Instructions Using Language, Vision, and Behavior
We define the problem of automatic instruction interpretation as follows. Given a natural language instruction, can we automatically predict what an instruction follower, such as a robot, should do in the environment to follow that instruction? Previous ...
Machine Learning for Social Multiparty Human--Robot Interaction
We describe a variety of machine-learning techniques that are being applied to social multiuser human--robot interaction using a robot bartender in our scenario. We first present a data-driven approach to social state recognition based on supervised ...
Nonstrict Hierarchical Reinforcement Learning for Interactive Systems and Robots
Conversational systems and robots that use reinforcement learning for policy optimization in large domains often face the problem of limited scalability. This problem has been addressed either by using function approximation techniques that estimate the ...
