In this video, PCA stands for Principal Component Analysis. It is introduced as the specific dimensionality-reduction method used as the example in this clip.
Conditions: Used as the naming definition for the method discussed in this segment.

A dominant strategy equilibrium is a specific type of Nash equilibrium. It occurs when all players in the game are playing their dominant strategies.
Conditions: All players must have and play a dominant strategy for it to be a dominant strategy equilibrium.; A Nash equilibrium only requires mutual best responses, which may or may not be dominant strategies.

The video states that dimensionality reduction is needed because data can have too many dimensions, which can often become a curse. Reducing the number of dimensions helps make the data more manageable and easier to process.
Conditions: Applies when data has many dimensions.; Presented as an introductory motivation, not as a formal theorem.
