Robust averaging during perceptual judgment is not optimal.
de Gardelle and Summerfield (1) claimed that, when judging the mean of a set of stimuli, it is optimal to downweight outliers, and that human subjects follow this robust averaging strategy. Here, we show that, in their task, the optimal observer would equally weight all observations. In ref. 1, subjects were presented with a set of eight colors that are denoted by a vector x = (x 1 ,. . ., x 8)...
متن کاملRobust averaging during perceptual judgment.
An optimal agent will base judgments on the strength and reliability of decision-relevant evidence. However, previous investigations of the computational mechanisms of perceptual judgments have focused on integration of the evidence mean (i.e., strength), and overlooked the contribution of evidence variance (i.e., reliability). Here, using a multielement averaging task, we show that human obser...
متن کاملRobust Optimal Control of Flexible Spacecraft During Slewing Maneuvers
In this paper, slewing maneuver of a flexible spacecraft with large angle of rotation is considered and assuming structural frequency uncertainties a robust minimum-time optimal control law is developed. Considering typical bang-bang control commands with multiple symmetrical switches, a parameter optimization procedure is introduced to find the control forces/torques. The constrained minimizat...
متن کاملBeta oscillations reflect supramodal information during perceptual judgment.
Previous work on perceptual decision making in the sensorimotor system has shown population dynamics in the beta band, corresponding to the encoding of stimulus properties and the final decision outcome. Here, we asked how oscillatory dynamics in the medial premotor cortex (MPC) contribute to supramodal perceptual decision making. We recorded local field potentials (LFPs) and spikes in two monk...
متن کاملRobust Averaging Level Control
Frequent inlet flow changes typically cause problems for averaging level controllers. For a frequently changing inlet flow the upsets do not occur when the system is in steady state and the tank level at its set-point. For this reason the tuning of the level controller gets quite complicated, since not only the size of the upsets but also the time in between them relative to the hold up of the ...
