Frequently asked questions

What is batch active learning and how does it relate to optimization?

Batch active learning involves iteratively selecting batches of data points for labeling, combined with optimization techniques to refine the model’s parameters based on the newly labeled data.

Can you elaborate on Level 3: Advanced (Weeks 5-6)?

Level 3 focuses on advanced active learning strategies, including exploring more sophisticated query methods and adapting to complex model landscapes during the final weeks of study.

How does active learning apply specifically to deep learning models?

Active learning in deep learning leverages uncertainty estimation to prioritize which data samples contribute most effectively to training, reducing the need for vast amounts of labeled data and accelerating model convergence.

What are cost-sensitive and adaptive strategies within the context of active learning?

Cost-sensitive strategies account for the varying costs associated with labeling different types of data, while adaptive strategies dynamically adjust the query strategy based on model performance and evolving uncertainty.
