Let’s say, we have two distributions to be compared with each other. Cross entropy uses the idea that we discussed on entropy. Cross entropy measures entropy between two probability distributions. Let’s say the first probability distribution is represented as A, and the second probability distri...
Log loss:Also known as cross-entropy loss or logistic loss, it measures the difference between predicted probabilities and actual outcomes in classification models. For binary classification, it is often called “binary cross-entropy.” At the core of a logistic regression process is the decision o...
Machine learning algorithms learn from data to solve problems that are too complex to solve with conventional programming
When training a CNN, a loss function is used to measure the error between the predicted and actual output. Common loss functions include mean squared error for regression tasks and categorical cross-entropy for multi-class classification tasks. The backpropagation algorithm is then utilized to update...
To train this whole system we just make a sequence of random point mutations to everything, keeping mutations that don’t increase the loss (where the loss is basically the difference between predicted next values and actual next values, or, more precisely, the “categorical...

Machine Learning FAQ Softmax Regression (synonyms: Multinomial Logistic, Maximum Entropy Classifier, or just Multi-class Logistic Regression) is a generalization of logistic regression that we can use for multi-class classification (under the assumption that the classes are mutually exclusive). In ...
With data and a ml model, we calculate the gradient of the error function (RMSE or cross entropy) between what output was expected and what output was predicted. Reply Gokul April 16, 2021 at 1:55 pm # f(x + delta_x) = f(x) + f'(x) * delta_x Reply Gokul April 16, 202...

A loss layer computes how the network training penalizes the deviation between the predicted and true labels, using a Softmax or cross-entropy loss for classification or a Euclidean loss for regression. Natural language processing (NLP) is another major application area for deep learning. ...
