A Correct answer
Explanation

Early stopping is a technique used to prevent overfitting in machine learning models. It involves monitoring the model's performance on a validation set during training and stopping the training process when the model starts to overfit the training data.

Multiple choice

What is the purpose of batch normalization in deep neural networks?

  1. Accelerating Convergence

  2. Preventing Overfitting

  3. Reducing Internal Covariate Shift

  4. Regularizing the Model

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Batch normalization is a technique used in deep neural networks to reduce internal covariate shift. Internal covariate shift occurs when the distribution of activations in a neural network changes during training, which can make the network more difficult to train. Batch normalization helps stabilize the distribution of activations by normalizing them across each batch of data.

  1. Mean Squared Error

  2. Cross-Entropy Loss

  3. Hinge Loss

  4. Absolute Error

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cross-Entropy Loss is a widely used loss function for multi-class classification tasks in machine learning. It measures the difference between the predicted probability distribution and the true probability distribution of the class labels. Minimizing Cross-Entropy Loss helps the model learn to make accurate predictions for multiple classes.

Multiple choice

What is the purpose of dropout in deep neural networks?

  1. Preventing Overfitting
