Conditional Similarities
Conditional probabilities P(j|i) in high-dimensional space calculated according to a Gaussian distribution centered on each point.
Begriffe
Joint Similarities
Symmetrized probabilities P(i,j) used to measure mutual similarities between pairs of points in the original space.
Begriffe
Distance Metric
Dissimilarity function used to calculate distances in high-dimensional space, typically Euclidean distance but can be adapted.
Begriffe
Parametric t-SNE
Variant using a neural network to learn a mapping function from high to low-dimensional space, allowing projection of new data.
Begriffe
UMAP
Alternative dimensionality reduction algorithm offering better preservation of global structure and faster computation times than t-SNE.
