Unsupervised learning of features and object boundaries from local prediction
Heiko H. Schütt, Wei Ji Ma
A visual system has to learn both which features to extract from images and how to group locations into (proto-)objects. Those two aspects are usually dealt with separately, althou…
Unbiased and Efficient Log-Likelihood Estimation with Inverse Binomial Sampling
Bas van Opheusden, Luigi Acerbi, Wei Ji Ma
The fate of scientific hypotheses often relies on the ability of a computational model to explain the data, quantified in modern statistical approaches by the likelihood function.…
Optimal allocation of attentional resource to multiple items with unequal relevance
Nuwan de Silva, Wei Ji Ma
In natural perception, different items (objects) in a scene are rarely equally relevant to the observer. The brain improves performance by directing attention to the most relevant…
Loss of information in feedforward social networks
Simon Stolarczyk, Manisha Bhardwaj, Kevin E. Bassler +2
We consider model social networks in which information propagates directionally across layers of rational agents. Each agent makes a locally optimal estimate of the state of the wo…
Visual Decisions in the Presence of Measurement and Stimulus Correlations
Manisha Bhardwaj, Sam Carroll, Wei Ji Ma +1
Humans and other animals base their decisions on noisy sensory input. Much work has therefore been devoted to understanding the computations that underly such decisions. The proble…
