Data Science and Machine Learning (Theory and Projects) A to Z - DNN and Deep Learning Basics: DNN Early Stopping

The video tutorial explains early stopping, a technique used to prevent overfitting in model training by monitoring training and validation losses. It highlights the importance of the validation set and introduces the patience parameter, which helps decide when to stop training. The tutorial concludes with a brief mention of hyperparameters, which will be discussed in the next video.

What is the primary purpose of a validation set in training neural networks?

• To replace the training set when it becomes too large

• To monitor the model's performance and prevent overfitting

• To provide additional data for testing

• To increase the size of the training set

What does it indicate if the training loss decreases but the validation loss starts to increase?

• The model needs more data

• The model is underfitting

• The model is overfitting

• The model is performing optimally

What is the role of the patience parameter in early stopping?

• To increase the batch size

• To decide the number of epochs to wait before stopping

• To determine the initial learning rate

• To adjust the model's architecture

Which of the following is a technique used to prevent overfitting by halting training?

• Early stopping

• Batch normalization

• Data augmentation

• Dropout

What topic is hinted at for discussion in the next video?

• Model evaluation

• Data preprocessing

• Hyperparameters

• Transfer learning
