Interests

I study Bayesian active sensing in sensorimotor control. Up until now the field has focused primarily on visual search tasks. I aim to go beyond the conventional and explore active sensing in more complex scenarios both experimentally and theoretically. We have recently developed a novel paradigm for visual categorization, in which we presented patterns generated with Gaussian processes as stimuli and controlled the visual information participants could obtain via a gaze-contingent display. We simulated the 'eye movements' of the optimal Bayesian active sensor under the same experimental condition and showed, by comparing the participants' eye movements to the optimal ones, that human active sensing is near-optimal under this setting. I plan to extend the paradigm and model from the visual system to the motor system and eventually to a combination of the two.
