Abstract(in English) | We propose fast receptive eld(RF) inference. The RF describes how a neuron sums up its inputs acrossspace and time. The traditional RF estimators such as the spike-triggered average, converge slowly and often requirelarge amounts of spike data. Previous research introduce a family of prior distribution to low cost estimation, byutilizing an approach known as empirical Bayes. In this study, we estimate the accurate RF by using regressionanalysis and variable selection based on the least absolute shrinkage and selection operator (Lasso) with respect tothe Fourier coefficients of the STA data. On the assumption that the RF has sparsity in the Fourier representation, the Lasso gives the denoised RF estimator. We compare our proposed method with the previous Bayesian methods, in the experiments of RF estimation by using articial and real data sets. We show that our method is robusterthan the previous method and can estimate fast and accurately, in the case that the observed spike data are few. |
