Abstract

Robust modeling approaches have received considerable attention due to its practical value to deal with the presence of outliers in data. This paper proposes a probabilistic robust learning algorithm for neural networks with random weights (NNRWs) to improve the modeling performance. The robust NNRW model is trained by optimizing a hybrid regularization loss function according to the sparsity of outliers and compressive sensing theory. The well-known expectation maximization (EM) algorithm is employed to implement our proposed algorithm under some assumptions on noise distribution. Experimental results on function approximation as well as UCI data sets for regression and classification demonstrate that the proposed algorithm is promising with good potential for real world applications.
