SUMMARY
The positive-only sigmoid function is primarily utilized in neural networks due to its ability to provide a monotonically increasing output, typically ranging from 0 to 1. This characteristic allows for effective modeling of biological systems by introducing non-linearity, which is essential for simulating complex behaviors in neural networks. The standard equation for this function is 1.0 / (1.0 + e^(-x)). Its design facilitates the activation of nodes, enabling them to represent varying degrees of activation, which is crucial for learning and error correction in neural network architectures.
