Iam planning to do some literature work on rationale neural networks and functionalities of activation functions like sigmoid and others, please recommend me some effective articles related one
The best-suited activation function for real-time scenarios in neural networks depends on the specific task and the desired performance characteristics. However, some of the most commonly used and effective activation functions for real-time applications include:
Rectified Linear Unit (ReLU): ReLU is a simple and efficient activation function that outputs the input directly if it is positive, or zero otherwise. It is widely used in deep neural networks due to its computational efficiency and non-saturating nature.
Leaky Rectified Linear Unit (Leaky ReLU): Leaky ReLU is a variant of ReLU that allows a small positive output for negative inputs. This helps to prevent the "dying ReLU" problem, where neurons become inactive due to consistently negative inputs.
Exponential Linear Unit (ELU): ELU is another variant of ReLU that introduces a slight exponential curve for negative inputs. This helps to improve the gradient flow and prevent vanishing gradients.
Scaled Exponential Linear Unit (SELU): SELU is a scaled version of ELU that introduces a scaling factor of 1.7515. This helps to stabilize the training process and improve convergence.
Hyperbolic Tangent (tanh): tanh is a sigmoid-like activation function that outputs values between -1 and 1. It is often used in recurrent neural networks (RNNs) for its ability to capture long-range dependencies in sequential data.
The choice of activation function depends on various factors such as the type of neural network, the nature of the task, and the desired trade-off between accuracy and computational efficiency. It is often beneficial to experiment with different activation functions to find the one that performs best for a particular application.
I recommend Sigmoid because the output values between 0 and 1 make it suitable for binary classification problems. Best for the output layer in binary classification problems. They are also used in certain cases for hidden layers in specific scenarios.
