Motion codeword generation using selective subsequence clustering for human action recognition
The understanding of human activity is one of the key research areas in human-centered robotic applications. In this paper, we propose complexity-based motion features for recognizing human actions. Using a ti...

Modeling and evaluating Gaussian mixture model based on motion granularity
To model manipulation tasks, we propose a novel method for learning manipulation skills based on the degree of motion granularity. Even though manipulation tasks usually consist of a mixture of fine-grained an...

Motion-Based Learning
In this Chapter, we introduce several learning approaches to generate non-preprogrammed motions for a virtual human. Motion primitives and their causalities should first be learned from a task, which consists ...

Autonomous framework for segmenting robot trajectories of manipulation task
In manipulation tasks, motion trajectories are characterized by a set of key phases (i.e., motion primitives). It is therefore important to learn the motion primitives embedded in such tasks from a complete de...

Skill Learning and Inference Framework
We propose a skill learning and inference framework, which includes five processing modules as follows: 1) human demonstration process, 2) autonomous segmentation process, 3) process of learning dynamic moveme...

Plk2 attachment to NSF induces homeostatic removal of GluA2 during chronic overexcitation
The authors find that the ATPase NSF interacts directly with Polo-like kinase 2 (Plk2), an activity-inducible kinase that is known to homeostatically decrease excitatory synapse number and strength. Plk2 disru...

Learning of Subgoals for Goal-Oriented Behavior Control of Mobile Robots
Subgoal learning is investigated to effectively build a goal-oriented behavior control rule with which a mobile robot can achieve a task goal for any starting task configurations. For this, states of interest ...

Distinct molecular mechanisms and divergent endocytotic pathways of AMPA receptor internalization
Internalization of postsynaptic AMPA receptors depresses excitatory transmission, but the underlying dynamics and mechanisms of this process are unclear. Using immunofluorescence and surface biotinylation, we ...

Growth of the NMDA receptor industrial complex
Grant et. al. use mass spectroscopy to identify new components of the NMDA receptor-associated protein complex, revealing a more complex postsynaptic organization than previously thought.

A new class II rice chitinase, Rcht2, whose induction by fungal elicitor is abolished by protein phosphatase 1 and 2A inhibitor
Among the four classes of chitinase, a class II chitinase had not yet been reported for rice. We have isolated and characterized a class II acidic chitinase, Rcht2, from rice (Oryza sativa L. cv. Cheongcheongb...
