Dropout
Dropout is a popular technique used in machine learning to prevent AI models from becoming too focused on training data and failing with new information. Think of it like training wheels for AI - it helps the system learn better by temporarily turning off some parts during training, similar to how a teacher might cover parts of a textbook to ensure students truly understand the material rather than just memorizing it. When you see this term in resumes or job descriptions, it usually refers to implementing or working with this learning technique, particularly with neural networks.

Example Interview Questions
Senior Level Questions
Q: How would you decide when and where to implement Dropout in a neural network?
Expected Answer: A senior candidate should explain how they analyze model performance to determine if Dropout is needed, consider the trade-offs between model accuracy and training time, and describe different Dropout rates for different layers based on network architecture.
Q: What alternatives to Dropout have you used for preventing overfitting?
Expected Answer: They should discuss various techniques like data augmentation, early stopping, and regularization, comparing their effectiveness to Dropout in different scenarios.
Mid Level Questions
Q: Explain how Dropout affects model training time and performance?
Expected Answer: Should be able to explain that Dropout might increase training time but improves model reliability, and describe how they've used it in real projects.
Q: What Dropout rate do you typically use and why?
Expected Answer: Should explain common Dropout rates (like 0.5 for hidden layers, 0.2 for input layers) and how they determine appropriate rates for different situations.
Junior Level Questions
Q: What is Dropout and why is it used?
Expected Answer: Should be able to explain that Dropout randomly deactivates neurons during training to prevent overfitting, using simple terms and basic examples.
Q: How do you implement Dropout in a basic neural network?
Expected Answer: Should demonstrate knowledge of adding Dropout layers in common frameworks, even if the understanding is basic.
