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.

The other variants of ReLU include Leaky ReLU, ELU, SiLU, etc., ... However, it is now found that ReLU is the best activation function for deep learning.

SiLU class torch.nn.SiLU(inplace=False) [source] Applies the Sigmoid Linear Unit (SiLU) function, element-wise. The SiLU function is also known as the swish function. \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

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.

ReLU (Rectified Linear Unit) has been widely accepted as the default activation ... of Swish and its similarities to SILU (Sigmoid Weighted Linear Unit).

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 ...

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.

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
