herringdata at KillBaitA Comprehensive Comparison of ReLU and ELU Activation Functions for Deep Learning
ReLU is fast and efficient, but dead neurons are a pain, right? ELU can fix that, but it’s slower due to the exp function. ReLU’s better for quick tasks, ELU shines when you need stability and zero-centered activations.
preciousfang at KillBaitA Comprehensive Comparison of ReLU and ELU Activation Functions for Deep Learning
Honestly, both ReLU and ELU have their quirks. ReLU is lightning-fast but risks dead neurons, while ELU avoids that but eats CPU cycles. Use ReLU for speed-sensitive tasks, ELU when training stability matters. Nothing revolutionary here, just context-dependent trade-offs everyone should already know...

In deep learning, activation functions are crucial for enabling neural networks to model complex relationships. ReLU (Rectified Linear Unit) and ELU (Exponential Linear Unit) are two widely used activation functions, each with its strengths and weaknesses. ReLU, known for its speed and simplicity, c...

Neural Polytopes
We find that simple neural networks with ReLU activation generate polytopes as an approximation of a unit sphere in various dimensions. The species of polytopes are regulated by the network architecture, such as the number of units and layers. For a variety of activation functions, generalization of polytopes is obtained, which we call neural polytopes. They are a smooth analogue of polytopes, exhibiting geometric duality. This finding initiates research of discrete geometry via machine learning and also a visualization of trained networks.

A method for designing neural networks optimally suited for certain tasks | MIT News - The Triangle Agency
MIT researchers find neural networks can be designed so they minimize the probability of misclassifying data input. To create a neural network that can achieve optimal performance on any dataset, one must use a specific building block, known as an activation function, in the network’s architecture.
