Discrimination (PsychologyBehavior, AnimalNeural InhibitionUp-RegulationFeedback, PhysiologicalSparse coding may be a general strategy of neural systems for augmenting memory capacity. In Drosophila melanogaster, sparse odor coding by the Kenyon cells of the mushroom body is thought to generate a large ...

Moreover, a multi-hypergraph learning framework to automatically select the optimal manifold structure is integrated into the objective of sparse coding learning, resulting in multi-hypergraph incidence Consistent Sparse Coding (MultiCSC). We show that the MultiCSC objective function can be optimized ...
First of all, representing an item as a distribution rather than a point in space connects with population coding in neural populations (Pouget, Dayan, & Zemel, 2000). The width of these distributions then also represents the strength of the modulation that is exerted on neighbouring neurons, ...
we address the problem of recognizing the user under different activities. In the proposed Gait-watch, we first present a feature extraction technique that can extract discriminative features from user’s gait signal. Then we employ sparse coding to build different training dictionaries for different ...

For better comparability, SampEn estimates from successive data points (with equating the number of pattern comparisons, see Methods) are also provided [color coding as in (A)]. Note. Error bars indicate the SD of the SampEn values across 1,000 randomly generated time series, hence represent ...
a sparse constraint denoising algorithm in the curvelet domain is proposed based on compressed sensing (CS) and is applied to the denoising of OVT gathers with a low signal-to-noise ratio (SNR).First, the seismic data are represented in the curvelet domain.Then, noise-related information is ...
