UnverifiedThe Spearman correlation coefficient is a non-parametric statistical method for measuring the strength of a monotonic relationship between two variables, ranging from -1 to 1, calculated based on variable rankings (ranks), and it does not require the data to follow a normal distribution nor assume a linear relationship.67% similarUnverifiedCosine similarity measures the cosine of the angle between two vectors, normalizes by the magnitude of the vectors in the denominator, and completely ignores vector magnitude while only caring about direction.66% similarVerifiedWhen feature vectors are L2-normalized, cosine similarity is equivalent to the dot product operation.64% similarUnverifiedMutual information measures the statistical dependence between two random variables, can capture dependencies of any form, including nonlinear and non-monotonic relationships, and is applicable to combinations of categorical and numerical variables.64% similarUnverifiedAll representational similarity metrics share a common implicit assumption: the condition set is accepted as a given, and the condition set is fixed by two decisions—which inputs are included and how they are grouped—both of which occur before the matrix exists.62% similar
