Abstract:
|
Despite the great success of applications of neural networks in many different fields, such as natural language processing and image recognition, lack of research focuses on the interpretation of neural network models. In this paper, we propose a sieve quasi-likelihood ratio test based on neural networks with one hidden layer to conduct significance tests of input features. The test statistic has asymptotic chi-squared distribution so that it is easy to apply in real data analysis. The validity of the asymptotic distribution is investigated via simulation and we applied our proposed test to perform genetic association analysis on the sequencing data from Alzheimer's Disease Neuroimaging Initiative (ADNI).
