They provide a coordinate system that allows us to express any vector as a linear combination of basis vectors. In ai models, basis vectors are used to represent data points and input features, forming the foundation for training and inference.
• Spanning and linear independence: Vector spaces can be spanned by a set of vectors, meaning that any vector within the space can be expressed as a linear combination of these vectors. Linear independence refers to a set of vectors that are not redundantly dependent on each other. Spanning and linear independence are fundamental concepts for understanding the structure and dimensionality of data in ai models.
• Norms and distances: Norms are functions that assign a non-negative value to a vector, representing its magnitude or length. Distances are measures of how far apart two vectors are within a vector space. Norms and distances are crucial for assessing the similarity or dissimilarity between data points, enabling algorithms to make decisions based on their proximity.
