These is usually acquired through extractors, if done meticulously. The evaluate of adequate randomness in extractors is min-entropy, a price associated with Shannon entropy by way of Rényi entropy; Rényi entropy is likewise used in evaluating randomness in cryptographic techniques. Despite the fact that linked, the distinctions amongst these actions suggest that a random variable with large Shannon entropy just isn't necessarily satisfactory to be used within an extractor and so for cryptography works by using.

This is due to B-tree indexes lead to query occasions weather proportional to log(n) wherever n is the amount of rows in a very desk and hash indexes cause constant time queries (no measurement dependency providing the suitable Portion of the index fits into memory).

Although it is usually made use of as a 'length metric', KL divergence will not be a real metric due to the fact It's not symmetric and won't fulfill the triangle inequality (which makes it a semi-quasimetric).
