Abstract

Sigmoid function and ReLU are commonly used activation functions in neural networks (NN). However, sigmoid function is vulnerable to the vanishing gradient problem, while ReLU has a special vanishing gradient problem that is called dying ReLU problem. Though many studies provided methods to alleviate this problem, there has not been an efficient feasible solution. Hence, we proposed a method replacing the original derivative function with an artificial derivative in a pertinent way. Our method optimized gradients of activation functions without varying activation functions nor introducing extra layers. Our investigations demonstrated that the method can effectively alleviate the vanishing gradient problem for both ReLU and sigmoid function with few computational cost.

  • In high-dimensional feature graphs, the inverted residual structure uses ReLU; in low-dimensional feature graphs, a linear activation function is used to solve information loss caused by ReLU.

    “As shown in Figure 6, in high-dimensional feature graphs, the inverted residual structure uses the ReLU activation function [35], while in low-dimensional feature graphs, in order to solve the problem of information loss caused by the ReLU function when dealing with low-dimensional information, the linear activation function [36] is usually used.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
