WebFeb 22, 2024 · The most common loss function for training a binary classifier is binary cross entropy (sometimes called log loss). You can implement it in NumPy as a one … In information theory, the binary entropy function, denoted $${\displaystyle \operatorname {H} (p)}$$ or $${\displaystyle \operatorname {H} _{\text{b}}(p)}$$, is defined as the entropy of a Bernoulli process with probability $${\displaystyle p}$$ of one of two values. It is a special case of See more In terms of information theory, entropy is considered to be a measure of the uncertainty in a message. To put it intuitively, suppose $${\displaystyle p=0}$$. At this probability, the event is certain never to occur, and … See more The derivative of the binary entropy function may be expressed as the negative of the logit function: See more The following bounds hold for $${\displaystyle 0
