Applies the Sigmoid Linear Unit (SiLU) function, element-wise. The SiLU function is also known as the swish function. silu ( x) = x ∗ σ ( x), where σ ( x) is the logistic sigmoid. \text {silu} (x) = x * \sigma (x), \text {where } \sigma (x) \text { is the logistic sigmoid.} silu(x) = x∗σ(x),where σ(x) is the logistic sigmoid. Note.

In the context of artificial neural networks, the rectifier or ReLU (Rectified Linear Unit) activation function is an activation function defined as the positive part of its argument: f ( x ) = x + = max ( 0 , x ) {\displaystyle f (x)=x^ {+}=\max (0,x)} where x is the input to a neuron. This is also known as a ramp function and is analogous to ...

Simply put, Swish is an extension of the SILU activation function which was proposed in the paper " Sigmoid-Weighted Linear Units for Neural Network Function Approximation in Reinforcement Learning ". SILU's formula is f (x) = x∗ sigmoid(x) f ( x) = x ∗ s i g m o i d ( x), where sigmoid(x) = 1 1+e−x s i g m o i d ( x) = 1 1 + e − x.

可以看到，ReLU+SiLU相比SiLU低1.1个点左右，比ReLU高1个点，ReLU+SiLU是推理速度与mAP值较好的折中方案。注：虽然Yolov5中没有使用解耦头和SimOTA，但测试模型速度时是带了解耦头的，这里也大概反映出了SiLU和ReLU对mAP值的影响。

Aug 22, 2019 · Leaky ReLU. Leaky Rectified Linear Unit. This activation function also has an alpha $\alpha$ value, which is commonly between $0.1$ to $0.3$. The Leaky ReLU activation function is commonly used, but it does have some drawbacks, compared to the ELU, but also some positives compared to ReLU. The Leaky ReLU takes this mathematical form

Leaky ReLUs allow a small, positive gradient when the unit is not active. Parametric ReLUs (PReLUs) take this idea further by making the coefficient of leakage into a parameter that is learned along with the other neural-network parameters. Note that for a ≤ 1, this is equivalent to and thus has a relation to "maxout" networks.
