Strategy Change in Vibrissal Active Sensing during Rat Locomotion
During exploration, rats and other small mammals make rhythmic back-and-forth sweeps of their long facial whiskers (macrovibrissae) [1-3]. These "whisking" movements are modulated by head movement [4] and by vibrissal sensory input [5, 6] and hence are often considered "active" in the Gibsonian sense of being purposive and information seeking [7, 8]. An important hallmark of active sensing is t...
متن کاملActive Sensing
Labels are often expensive to get, and this motivates active learning which chooses the most informative samples for label acquisition. In this paper we study active sensing in a multi-view setting, motivated from many problems where grouped features are also expensive to obtain and need to be acquired (or sensed) actively (e.g., in cancer diagnosis each patient might go through many tests such...
متن کاملDifferentiation requires continuous active control.
The problems posed by differentiation that appear most soluble by a passive control mechanism can readily be solved by an active mechanism. Given the need for plasticity in gene expression in different cell types at different stages, an active mechanism may be advantageous, even essential. It is striking how few changes during differentiation are completely irreversible, the gene rearrangements...
