Randomness Tests for Binary Sequences
… digital world. Though sometimes underestimated, randomness plays a key role in cryptography, generating unpredictable keys and other related material. Hence, high-quality random number generators are a crucial element in building a secure cryptographic system. In dealing with randomness, two key …

Randomness In Tree Ensemble Methods
Tree ensembles have proven to be a popular and powerful tool for predictive modeling tasks. The theory behind several of these methods (e.g. boosting) has received considerable attention. However, other tree ensemble techniques (e.g. bagging, random forests) have attracted limited theoretical …

Distributed computing with imperfect randomness
Randomness is a critical resource in many computational scenarios, enabling solutions where deterministic ones are elusive or even provably impossible. However, the randomized solutions to these tasks assume access to a pure source of unbiased, independent coins. Physical sources of randomness, on …

Players with Bounded Randomness Capabilities
In this thesis I study the effect of bounded randomness capabilities on the outcomes of games, and their payoffs to the players. I study this subject from two perspectives. The first perspective is the ability to share randomness across team members playing against an opposing team. The second …

Uncertainty's Impact on Perceptions Toward Randomness
The current study examined the effects that perceived uncertainty and success in a financial decision task had on participant’s attitudes toward uncertainty. One hundred and fifty-three participants were randomly assigned to read one of three possible vignettes in which varying levels of …

Separability within alternating groups and randomness
This thesis promotes known residual properties of free groups, surface groups, right angled Coxeter groups and right angled Artin groups to the situation where the quotient is only allowed to be an alternating group. The proofs follow two related threads of ideas. The first thread leads to …

On quantum randomness and quantum resources
… The first part is on entanglement, quantum randomness, and complexity beyond scrambling. More explicitly, we study the Rényi entanglement entropies of quantum designs. The results lay the mathematical foundation for studying the hierarchy of complexities in between scrambling and Haar …

Trading isolation for certifiable randomness expansion
… which we will refer to broadly as Certifiable Randomness Expansion (CRE). CRE refers generally to a process by which a source of information-theoretically certified randomness can be constructed based only on two simple assumptions: the prior existence of a short random seed and the ability to …

Algebraic methods in randomness and pseudorandomness
Algebra and randomness come together rather nicely in computation. A central example of this relationship in action is the Schwartz-Zippel lemma and its application to the fast randomized checking of polynomial identities. In this thesis, we further this relationship in two ways: (1) by compiling …

Quantum randomness expansion : upper and lower bounds
… a source of information-theoretically certified randomness can be constructed based only on two simple assumptions: the prior existence of a short random seed and the ability to ensure that two black-box devices do not communicate (i.e. are non-signaling). We call protocols achieving such …

Value Indefiniteness, Randomness and Unpredictability in Quantum Foundations
… to be random, but despite the fact that this randomness is an important element in quantum information theory, its nature is not well understood. In this thesis, we study several issues relating to the origin and certification of quantum randomness and unpredictability. One of the key results …

Algorithmic randomness on computable metric spaces and hyperspaces
… we shall be focusing on generalizing Martin-Löf randomness to computable metric spaces with arbitrary measure (for examples of this type of generalization see Gács [14], Rojas and Hoyrup [15]. The aim of this generalization is to define algorithmic randomness on the hyperspace of non-empty …

Trading structure for randomness in wireless opportunistic routing
… mixes packets before forwarding them. This randomness ensures that routers that hear the same transmission do not forward the same packets. Thus, MORE needs no special scheduler to coordinate routers and can run directly on top of 802.11. We analyze the theoretical gains provided by …

Flow randomness and tip losses in transonic rotors
… with data from the three rotors. Also, randomness calculations are performed for each rotor. The flowfield randomness of the two fans is shown to correlate well with their respective high tip losses. The core compressor is shown to have a very random flowfield, with no identifiable blade …
