Getting More Randomness

چکیده

Theorem 1.1 (Number of Samples for Class with Bounded VC-Dimension) Suppose (X,C) has VC-dimension at most d. Then, suppose S is a subset obtained by sampling from X independently m times. If m ≥ max{ log 2 δ , 8d log 8d }, then with probability at least 1− δ, S is an -net. Using VC-dimension, we can bound the number of effective boolean functions on the random subset S. However, after conditioning on S, there is no more randomness left. We see how we can introduce extra artificial randomness in the analysis in order to make the proof works.

A Randomness Test for Stable Data

In this paper, we propose a new method for checking randomness of non-Gaussian stable data based on a characterization result. This method is more sensitive with respect to non-random data compared to the well-known non-parametric randomness tests.

Improving Tor security against timing and traffic analysis attacks with fair randomization

The Tor network is probably one of the most popular online anonymity systems in the world. It has been built based on the volunteer relays from all around the world. It has a strong scientific basis which is structured very well to work in low latency mode that makes it suitable for tasks such as web browsing. Despite the advantages, the low latency also makes Tor insecure against timing and tr...

Bertrand’s Paradox Revisited: More Lessons about that Ambiguous Word, Random

The Bertrand paradox question is: “Consider a unit-radius circle for which the length of a side of an inscribed equilateral triangle equals 3 . Determine the probability that the length of a ‘random’ chord of a unit-radius circle has length greater than 3 .” Bertrand derived three different ‘correct’ answers, the correctness depending on interpretation of the word, random. Here we employ geomet...

Entropy, Randomness, and Information

“If only once only once no matter where, no matter before what audience I could better the record of the great Rastelli and juggle with thirteen balls, instead of my usual twelve, I would feel that I had truly accomplished something for my country. But I am not getting any younger, and although I am still at the peak of my powers there are moments why deny it? when I begin to doubt and there is...

Sampling Based EM Algorithm

A sampling based EM algorithm is proposed. The algorithm tries to add some randomness to the likelihood function thereby increasing the chances of the convergence of the EM algorithm to the true maxima as against getting stuck in the local maximum of likelihood manifold. The experiments for the problem of parameter estimation for a mixture of two gaussians are presented. The improved accuracy i...
