Log based formula
Witryna15 lut 2024 · Logarithmic loss indicates how close a prediction probability comes to the actual/corresponding true value. Here is the log loss formula: Binary Cross-Entropy , Log Loss. Let's think of how the linear regression problem is solved. We want to get a linear log loss function (i.e. weights w) that approximates the target value up to … Witryna17 lis 2024 · Log-loss is indicative of how close the prediction probability is to the corresponding actual/true value (0 or 1 in case of binary classification). The more the predicted probability diverges from the actual value, the higher is the log-loss value. Consider the classification problem of spam vs. ham for emails.
