  • Mean Squared Error vs Cross Entropy Loss Function
    An example of the usage of cross-entropy loss for multi-class classification problems is training the model using the MNIST dataset Cross entropy loss for binary classification problem In a binary classification problem, there are two possible classes (0 and 1) for each data point The cross-entropy loss for binary classification can be
  • Why is cross entropy loss better than MSE for multi-class . . .
    The cross entropy loss is 0 74, and MSE loss is 0 08 If we change the predicted probabilities to: [0 4, 0 6, 0, 0], the cross-entropy loss is 1 32, and MSE loss 0 12 As expected, the cross-entropy loss is higher in the 2nd case because the predicted probability is lower for the true label
  • A comparison between MSE, Cross Entropy, and Hinge Loss
    Cross Entropy Loss: An information theory perspective As mentioned in the CS 231n lectures, the cross-entropy loss can be interpreted via information theory In information theory, the Kullback
  • NLP Interview Must-Ask: Why Do Large Models Use Cross-Entropy . . .
    Additionally, cross-entropy penalizes incorrect predictions more effectively than MSE For example, when y=1 but the model predicts p=0 1: MSE loss: (1–0 1)² = 0 81; Cross-entropy loss: −log⁡0 1=2 3; Clearly, cross-entropy imposes a higher penalty, allowing the model to adjust incorrect predictions more effectively
  • Understanding Technology Loss Functions: Cross-Entropy MSE
    Cross-entropy loss shines in such scenarios It measures the difference between the predicted probability distribution over classes and the true distribution How it works: Cross-entropy calculates the average "information gain" achieved by using the predicted probabilities compared to knowing the true class
