Learning to Selectively Attend
How is reinforcement learning possible in a high-dimensional world? Without making any assumptions about the structure of the state space, the amount of data required to effectively learn a value function grows exponentially with the state space’s dimensionality. However, humans learn to solve highdimensional problems much more rapidly than would be expected under this scenario. This suggests t...
متن کاملLearning to Attend Selectively: The Dual Role of Intersensory Redundancy.
Selective attention is the gateway to perceptual processing, learning, and memory, and is a skill honed through extensive experience. However, little research has focused on how selective attention develops. Here we synthesize established and new findings assessing the central role of redundancy across the senses in guiding and constraining this process in infancy and early childhood. We highli...
متن کاملDeep Learning to Attend to Risk in ICU
Modeling physiological time-series in ICU is of high clinical importance. However, data collected within ICU are irregular in time and often contain missing measurements. Since absence of a measure would signify its lack of importance, the missingness is indeed informative and might reflect the decision making by the clinician. Here we propose a deep learning architecture that can effectively h...
متن کاملLearning to Attend - From Bottom-Up to Top-Down
The control of overt visual attention relies on an interplay of bottom-up and top-down mechanisms. Purely bottom-up models may provide a reasonable account of the looking behaviors of young infants, but they cannot accurately account for attention orienting of adults in many natural behaviors. But how do humans learn to incorporate topdown mechanisms into their control of attention? The phenome...
متن کاملLearning to Attend to Threat Accelerates and Enhances Memory Consolidation
Practice on a procedural task involves within-session learning and between-session consolidation of learning, with the latter requiring a minimum of about four hours to evolve due to involvement of slower cellular processes. Learning to attend to threats is vital for survival and thus may involve faster memory consolidation than simple procedural learning. Here, we tested whether attention to t...
