ExpRoot+Log is a fast and interpretable function approximation method based on a hybrid linear basis. It combines exponential square-root, polynomial, and logarithmic terms to efficiently approximate ...

When writing custom distributions, it is often helpful to have numerically stable implementations of log_diff_exp(a, b) := log(exp(a) - exp(b)) and particularly log1m_exp(x) := log(1 - exp(x)). The ...
