Learning to stand with unexpected sensorimotor delays

چکیده
Human standing balance relies on self-motion estimates that are used by the nervous system to detect unexpected movements and enable corrective responses adaptations in control. These must accommodate for inherent delays sensory motor pathways. Here, we a robotic simulate human about ankles anteroposterior direction impose sensorimotor into control of balance. Imposed destabilized standing, but through training, participants adapted re-learned with delays. Before imposed attenuated vestibular contributions triggered perceptions motion, suggesting increased uncertainty internal estimates. After partially returned baseline levels larger were needed evoke motion. Through learning, accommodates causally linking whole-body feedback (initially interpreted as motion) self-generated commands.

Accessing data from numerous widely distributed sources poses signi cant new challenges for query opti mization and execution Congestion and failures in the network can introduce highly variable response times for wide area data access This paper is an initial ex ploration of solutions to this variability We introduce a class of dynamic run time query plan modi cation techniques that we call qu...
متن کاملDealing with delays does not transfer across sensorimotor tasks.
It is known that people can learn to deal with delays between their actions and the consequences of such actions. We wondered whether they do so by adjusting their anticipations about the sensory consequences of their actions or whether they simply learn to move in certain ways when performing specific tasks. To find out, we examined details of how people learn to intercept a moving target with...
متن کاملOnline Learning with Adversarial Delays
We study the performance of standard online learning algorithms when the feedback is delayed by an adversary. We show that online-gradient-descent [1] and follow-the-perturbed-leader [2] achieve regret O( √ D) in the delayed setting, where D is the sum of delays of each round’s feedback. This bound collapses to an optimal O( √ T ) bound in the usual setting of no delays (where D = T ). Our main...
