UMAP
UMAP is a dimensionality reduction technique used to visualize high-dimensional data in lower dimensions.
Undersampling
Undersampling is a technique used in data analysis to balance datasets by reducing the number of majority class examples.
Unsupervised Learning
Unsupervised learning is a type of machine learning where a model finds patterns and structure in data without using labeled examples.
Upper Confidence Bound
Upper Confidence Bound (UCB) is an algorithmic approach used in multi-armed bandit problems to balance exploration and exploitation by selecting options with the highest potential reward.
