That's the meaning of "exponential" in EWMA: each weight is a constant multiplier (i.e. lambda, which must be less than one) of the prior day's weight. This ensures a variance that is weighted or biased toward more recent data. The difference between simply volatility and EWMA for Goog...
We report the longitudinal evolutionary analysis of 126 non-small cell lung cancer (NSCLC) tumours from 421 prospectively recruited patients in TRACERx who developed metastatic disease, compared with a control cohort of 144 non-metastatic tumours. In 25% of cases, metastases diverged early, before ...

The meaning of DP is intuitive only to a superficial analysis. For example, one may at first think that removing the sensitive attribute from the decision making process is enough to guarantee independence and thus demographic parity. In general, this is not the case. Take the credit lending ...
In this paper the physical meaning of the empirical Kohlrausch-Williams-Watts (KWW) function is explained in terms of the linear oscillator theory. It is shown that the KWW function is a solution of the non-autonomous linear first order equation for an overdamped linear oscillator. From the ...
Only datasets consisting of features extracted in tabular form were included. All datasets were high-dimensional, meaning there were more features than samples, except for two datasets, Carvalho2018 and Saha2018. Table 1 Overview of the datasets Full size table Preprocessing For this study, the ...
error term and exp() denotes the exponential function (see Supplementary Information: "Ansatz functions" where we discuss other ansatz functions and different error specifications that have been suggested in the literature31,32,114 and justify our choice). Since we want A and b to be positive, ...
