An ideal observer model of infant object perception
2008
Neural Information Processing Systems
Preserved Fulltext
To illustrate this idea we develop an ideal observer model that incorporates probabilistic principles of rigidity and inertia. ...
Before the age of 4 months, infants make inductive inferences about the motions of physical objects. ...
An ideal observer approach An ideal observer approach to object perception can be formulated in terms of a generative model for scenes. Scenes can be generated in three steps. ...

Infants acquire knowledge by observing objects move in and out of sight, forming associations of these different views. ...
Evidence from computational modeling and from experiments with human infants highlights three kinds of learning that contribute to infants' knowledge of the visual world: learning via association, learning ...

As a function of perception of visual motion, this paper will describe behavioral and brain studies with young infants investigating the development of visual perception for prospective control. ...
During infancy, smart perceptual mechanisms develop allowing infants to judge timespace motion dynamics more efficiently with age and locomotor experience. ...
During visually guided actions, an observer reaches an ideal state when he acts to produce a certain pattern of visual flow. ...

In this study, we recorded electroencephalography (EEG) from infants (ages 4-11 months of age) and adults while they observed three types of actions: (a) reaching for an object; (b) walking; and (c) object ...
There were no group differences in global metric measures for observation of object motion or for observation of actions that are within the repertoire of infants (i.e., reaching). ...
We recently examined the EEG response of young infants while observing three types of actions: (a) reaching for an object; (b) independent walking; and (c) object motion. ...

First, as predicted, infants' COG samples from the occluded-object task are learned by a pool of simple recurrent networks faster than the samples produced by the yoked, artificial-observer models. ...
We conclude by relating our findings to the role of image-saliency and prediction-learning during the development of object perception. ...

Lastly, an ideal-observer model, even with resource and processing constraints, provides only a coarse approximation to the psychological mechanisms of infant cognition. ...

This paper describes a computational model of language acquisition based on meaningful interaction between an infant and its caregivers. ...
In this work, the model is used to study the effects of different attentional factors in learning of word-object paring during learner-caregiver interaction. ...
For example, an infant might hear an utterance from the caregiver, while at the same time not paying attention to exactly those objects referred to in that utterance. ...
