Piecewise Linear Unit:分段线性激活函数 激活函数在神经网络里是一个重要的组件,大家最常用的是ReLU,其变种在各种任务/模型中都有较好的效果。Swish这种搜索得到的激活函数,在部分数据集上也能超越ReLU,但是搜索效率不够高。 为此我们提出了PiecewiseLinearUnit,分段线性激活函数,通过公式设计+可学习参数,能够达到SOTA的...
piecewise linear differential systemsPoincare mapBIFURCATIONCIRCUITIn this paper we present a relationship between the algebraic notion of proper system, the geometric notion of contact point and the dynamic notion of Poincare map for piecewise linear differential systems. This allows to present sufficient...
As a powerful modelling method, piecewise linear neural networks (PWLNNs) have proven successful in various fields, most recently in deep learning. To apply PWLNN methods, both the representation and the learning have long been studied. In 1977, the canonical representation pioneered the works of ...
