In information theory, the binary entropy function, denoted or , is defined as the entropy of a Bernoulli process with probability of one of two values. It is a special case of , the entropy function. Mathematically, the Bernoulli trial is modelled as a random variable that can take on only two values: 0 and 1, which are mutually exclusive and exhaustive.

How to interpreter Binary Cross Entropy loss function?

If you are training a binary classifier, chances are you are using binary cross-entropy / log lossas your loss function. Have you ever thought about what exactly does it mean to use this loss function? The thing is, given the ease of use of today’s libraries and frameworks, it is very easy to overlook the true meaning of the … See more I was looking for a blog post that would explain the concepts behind binary cross-entropy / log loss in a visually clear and concise manner, so I … See more Let’s start with 10 random points: x = [-2.2, -1.4, -0.8, 0.2, 0.4, 0.8, 1.2, 2.2, 2.9, 4.6] This is our only feature: x. Now, let’s assign some colors … See more First, let’s split the points according to their classes, positive or negative, like the figure below: Now, let’s train a Logistic Regression to classify our points. The fitted regression is a sigmoid curve representing the … See more If you look this loss functionup, this is what you’ll find: where y is the label (1 for green points and 0 for red points) and p(y) is the predicted probability … See more WebJan 18, 2024 · Figure 1: The binary cross-entropy loss function ( image source ). Binary cross-entropy was a valid choice here because what we’re essentially doing is 2-class classification: Either the two images presented to the network belong to the same class Or the two images belong to different classes Framed in that manner, we have a … WebOur solution is that BCELoss clamps its log function outputs to be greater than or equal to -100. This way, we can always have a finite loss value and a linear backward method. … how is pension paid out
