Anomaly detection from hyperspectral imagery
…, EM Winter, AP Schaum, AD Stocker - IEEE signal …, 2002 - ieeexplore.ieee.org
We develop anomaly detectors, ie, detectors that do not presuppose a signature model of
one or more dimensions, for three clutter models: the local normal model, the global normal …

Noise characteristics and prior expectations in human visual speed perception
AA Stocker, EP Simoncelli - Nature neuroscience, 2006 - nature.com
Human visual speed perception is qualitatively consistent with a Bayesian observer that
optimally combines noisy measurements with a prior preference for lower speeds. Quantitative …

A Bayesian observer model constrained by efficient coding can explain'anti-Bayesian'percepts
XX Wei, AA Stocker - Nature neuroscience, 2015 - nature.com
Bayesian observer models provide a principled account of the fact that our perception of the
world rarely matches physical reality. The standard explanation is that our percepts are …

[HTML][HTML] Visual adaptation: Neural, psychological and computational aspects
The term visual adaptation describes the processes by which the visual system alters its
operating properties in response to changes in the environment. These continual adjustments in …

Sensory adaptation within a Bayesian framework for perception
AA Stocker, E Simoncelli - Advances in neural information …, 2005 - proceedings.neurips.cc
We extend a previously developed Bayesian framework for perception to account for sensory
adaptation. We first note that the perceptual effects of adaptation seems inconsistent with …

Lawful relation between perceptual bias and discriminability
XX Wei, AA Stocker - … of the National Academy of Sciences, 2017 - National Acad Sciences
Perception of a stimulus can be characterized by two fundamental psychophysical measures:
how well the stimulus can be discriminated from similar ones (discrimination threshold) …

Is the homunculus “aware” of sensory adaptation?
Neural activity and perception are both affected by sensory history. The work presented
here explores the relationship between the physiological effects of adaptation and their …

A Bayesian model of conditioned perception
AA Stocker, E Simoncelli - Advances in neural information …, 2007 - proceedings.neurips.cc
We propose an extended probabilistic model for human perception. We argue that in many
circumstances, human observers simultaneously evaluate sensory evidence under different …
