This paper studies robust learning methods for deep neural networks in the presence of outliers. While conventional training based on mean squared error (MSE) is optimal under normality assumptions, it is highly sensitive to anomalous observations commonly encountered in real-world data. To address this limitation, we adopt the minimum density power divergence framework, which enables a flexible trade-off between robustness and statistical efficiency through a tuning parameter. This paper extends the framework to univariate time series settings and shows that the resulting loss function down-weight the contribution of observations with large residuals to the gradient of model parameters during training. In addition, we integrate an outlier detection procedure based on standardized residuals and tail probability estimation. A data-driven strategy for selecting the tuning parameter is also provided. Simulation studies demonstrate the effectiveness of the proposed method in achieving robust estimation and reliable outlier detection.
