Sparse coding of sensory inputs has been observed to be a ubiquitous strategy employed in the nervous system of many species [1], [2], [3]. In these systems, only a small fraction of the neuronal population responds to any specific stimulus, and each neuron exhibits a high level of sele...
Sensorimotor transformation is indispensable to the accurate motion of the human body in daily life. For instance, when we grasp an object, the distance from our hands to an object needs to be calculated by integrating multisensory inputs and our motor system needs to appropriately activate the ...
by the input vector . Therefore, in sparse coding, we introduce the additional criterion of sparsity t o resolve the degeneracy introduced by over-completeness. 过完备的基能发掘出数据的内在结构和模型,但是其系数表示将不唯一 Here, we define sparsity as having few non-zero components or having few...
The dendritic compartment could then estimate the amount of somatic inhibition by comparing its local depolarisation with the somatic activity that it perceives via backpropagating action potentials. The idea has been tried before, although not on a sparse coding task. In Körding and König (...

Sparse coding can be applied to learn overcomplete dictionary, where the number of dictionary elements is larger than the dimension of the input data.
