James McCaffrey uses cross entropy error via Python to train a neural network model for predicting a species of iris flower. In this article, I explain cross entropy ...

Let 𝐺 be a sofic group, and let Σ = (𝜎𝑛)𝑛⩾₁ be a sofic approximation to it. For a probability-preserving 𝐺 -system, a variant of the sofic entropy relative to Σ has recently been defined in terms ...
