WebIt clearly holds for Gaussian vectors and it is not difficult to see that (1.1) is true for subgaussian vectors (see below for definitions) for every p ≥ 1, with C1 and C2 depending only on the subgaussian parameter. Another example of such a class is the class of so-called log-concave vectors. Web2 that the algorithms are robust against noise and an inaccurate initial estimate. Experiments with different initialization schemes show that our initialization algo-rithm signic
