Efficient Sparse Coding in Early Sensory Processing: Lessons from Signal Recovery
Sensory representations are not only sparse, but often overcomplete: coding units significantly outnumber the input units. For models of neural coding this overcompleteness poses a computational challenge for shaping the signal processing channels as well as for using the large and sparse representations in an efficient way. We argue that higher level overcompleteness becomes computationally tr...
متن کاملAdaptive sensory processing for efficient place coding
This work presents a neural model of self-localisation implemented on a simulated mobile robot with a realistic visual input. A population of modelled place cells with overlapping receptive fields is constructed online during exploration. In contrast to similar models of place cells, parameters of neurons in the sensory pathway adapt online to the environments statistics in order to maximise in...
متن کاملSparse Signal Recovery from Nonadaptive Linear Measurements
The theory of Compressed Sensing , the emerging sampling paradigm ‘that goes against the common wisdom’ , asserts that ‘one can recover signals in R from far fewer samples or measurements , if the signal has a sparse representation in some orthonormal basis, from m ≈ O(klogn), k ≪ n nonadaptive measurements . The accuracy of the recovered signal is as good as that attainable with direct knowled...
متن کاملSparse coding of sensory inputs.
Several theoretical, computational, and experimental studies suggest that neurons encode sensory information using a small number of active neurons at any given point in time. This strategy, referred to as 'sparse coding', could possibly confer several advantages. First, it allows for increased storage capacity in associative memories; second, it makes the structure in natural signals explicit;...
متن کاملEnergy-Efficient Sensor Censoring for Compressive Distributed Sparse Signal Recovery
To strike a balance between energy efficiency and data quality control, this paper proposes a sensor censoring scheme for distributed sparse signal recovery via compressive-sensing based wireless sensor networks. In the proposed approach, each sensor node employs a sparse sensing vector with known support for data compression, meanwhile enabling making local inference about the unknown support ...
