Data minimization is the principle of collecting, processing and storing only the necessary amount of personal information required for a specific purpose. The principle emanates from the realisation that processing unnecessary data is creating unnecessary risks for the data subject without creating any current benefit or value.
The assumption here is that third-parties cannot be trusted. Data protection goals include data minimization and the reduction of trust in third-parties. [2] Examples of such technologies include onion routing, the secret ballot, and VPNs [6] used for democratic elections.
Collection Limitation - Collection of data must be fair, lawful, and limited to the stated purpose. [18] Data minimization - Collection of data should be minimized as much as possible, and technologies should default to have users be non-identifiable and non-observable or minimized if absolutely necessary. [18]
For example, to aid in debugging of minified code, by "mapping" this code to the original unminified source code instead. The original format was created by Joseph Schorr as part of the Closure Inspector minification project. [9] Version 2 and 3 of the format reduced the size of the map files considerably. [9]
Powell's method, strictly Powell's conjugate direction method, is an algorithm proposed by Michael J. D. Powell for finding a local minimum of a function. The function need not be differentiable, and no derivatives are taken.
Although data minimisation is a requirement, with pseudonymisation being one of the possible means, the regulation provides no guidance on how or what constitutes an effective data de-identification scheme, with a grey area on what would be considered as inadequate pseudonymisation subject to Section 5 enforcement actions.
Also, the gain factor, +, depends on our confidence in the new data sample, as measured by the noise variance, versus that in the previous data. The initial values of x ^ {\displaystyle {\hat {x}}} and C e {\displaystyle C_{e}} are taken to be the mean and covariance of the aprior probability density function of x {\displaystyle x} .
The following is the skeleton of a generic branch and bound algorithm for minimizing an arbitrary objective function f. [3] To obtain an actual algorithm from this, one requires a bounding function bound, that computes lower bounds of f on nodes of the search tree, as well as a problem-specific branching rule.
