What are the challenges associated with evaluating the effectiveness of unsupervised learning algorithms, and what are some potential methods for this evaluation?
Evaluating the effectiveness of unsupervised learning algorithms presents a unique set of challenges that are distinct from those encountered in supervised learning. In supervised learning, the evaluation of algorithms is relatively straightforward due to the presence of labeled data, which provides a clear benchmark for comparison.
