Resumen
Statistical inference is at the heart of the probabilistic programming approach to artificial intelligence; as far as statistical inference is concerned, the Gibbs sampler is one of the most widely applicable and popular random sampling techniques. On the flip side, deterministic sampling is still nascent and has yet to be widely accepted into the field of Bayesian inference. In this thesis, we advance the domain of deterministic sampling by discussing and evaluating two deterministic sampling techniques inspired by the Gibbs sampler. The first technique is the recently-introduced herded

Texto completo
Resumen
In questa tesi studiamo l'effetto Gibbs. Tale fenomeno si manifesta tramite la presenza di sovra-oscillazioni nei polinomi di Fourier di funzioni che presentano discontinuità di prima specie. La differenza tra il massimo ed il minimo del polinomio di Fourier di tali funzioni, in prossimità di un punto di discontinuità della funzione, è strettamente maggiore del salto della funzione in quel punto, anche per n che tende all'infinito. Per attenuare le sovra-oscillazioni delle somme parziali di Fourier si utilizzano le serie di Fejer e si vede come effettivamente il fenomeno di Gibbs scompaia.

Resumen
L'effetto Gibbs è un fenomeno oscillatorio che riguarda i polinomi di Fourier. In particolare, ogni volta che si approssima una funzione periodica e regolare a tratti con il suo polinomio di Fourier associato, si può notare che, in prossimità dei punti di discontinuità di tipo salto di tale funzione, il polinomio presenta delle sovraelongazioni che non si attenuano all'aumentare del grado. Lo studio di questo fenomeno è stato diviso in tre parti. Nel primo capitolo vengono studiati i polinomi e le serie di Fourier e vengono forniti i principali risultati di convergenza.

Resumen
The Gibbs sampler is one of the most popular algorithms for inference in statistical models. In this thesis, we introduce a herding variant of this algorithm that is entirely deterministic. We demonstrate, with simple examples, that herded Gibbs exhibits better convergence behavior for approximating the marginal distributions than Gibbs sampling. In particular, image denoising exemplifies the effectiveness of herded Gibbs as an inference technique for Markov Random Fields (MRFs). Also, we adopt herded Gibbs as the inference engine for Conditional Random Fields (CRFs) in Named Entity Recognitio

L'argomento di questa tesi è il fenomeno di Gibbs, un fenomeno che riguarda dei particolari polinomi trigonometrici, i polinomi di Fourier: questi ultimi sono molto utilizzati per approssimare funzioni periodiche in quanto tra tutti i polinomi trigonometrici sono quelli che minimizzano l'errore in norma quadratica. Il fenomeno di Gibbs si può descrivere in questo modo: siano date una funzione f periodica che presenta punti di discontinuità di prima specie e la sua approssimazione tramite serie di Fourier; quando si tronca questa serie si avranno delle forti oscillazioni in prossimità dei punti

In the present thesis, we close a methodological gap of optimising the basic Markov Chain Monte Carlo algorithms. Similarly to the straightforward and computationally efficient optimisation criteria for the Metropolis algorithm acceptance rate (and, equivalently, proposal scale), we develop criteria for optimising the selection probabilities of the Random Scan Gibbs Sampler. We develop a general purpose Adaptive Random Scan Gibbs Sampler, that adapts the selection probabilities, gradually, as further information is accrued by the sampler.

Resumen
Gibbon classification at the species and subspecies levels has been hotly debated for the last 200 years. This thesis explores the reasons for this debate. Authorities agree that siamang, concolor, kloss and hoolock are species, while there is complete lack of agreement on lar, agile, moloch, Mueller's and pileated. The disagreement results from the use and emphasis of different character traits, and from debate on the occurrence and importance of gene flow.

Resumen
It is well known that given an arbitrary continuous and periodic function f(x), it is possible to represent it as a Fourier series. However, attempting to approximate a discontinuous or non periodic function, using a Fourier series, yields very poor results. Large oscillations and overshoots appear around the points of discontinuity. Regardless of the number of terms that are included in the series, these overshoots do not disappear, they simply move closer to the point of discontinuity. This is known as the Gibbs phenomenon.

Summary The paper investigates the Gibbs’ phenomenon at a jump discontinuity for Fourier–Bessel series expansions. The unexpected thing is that the Gibbs’ constant for Fourier–Bessel series appears to be the same as that for Fourier series expansions. In order to compute the coefficients for Fourier–Bessel functionsefficiently, several integral formulasare derived and the Struve functions and their asymptotic expansions discussed, all of which significantly ease the computations.

In order to see how non deterministic a parallel execution can extend up to, creates the need of the ensemble of executions.

This thesis examines Lewis Grassic Gibbon/James Leslie Mitchell's promotion of the transformative power of the feminine and its offshoot of freer sexuality as a basis for new relationships among individuals, their societies and the world. As a result of Gibbon's revaluation of gender values, the feminine becomes identified as innate human "good," largely subsumed under, and set in opposition to, the evil perpetrated by the masculine historical process. Distinct from actual women, the feminine can be reclaimed by men too, affecting Gibbon's representations of both sexes. The feminine emerges as

We exploit this formalism to deduce the conclusion of the Hammersley-Clifford Theorem for a family of Markov random fields which are outside the theorem's purview (including Markov random fields whose support is the d-dimensional "3-colored chessboard").

Resumen
On introduit un formalisme de mécanique statistique pour l'étude des processus stochastiques discrets(chaînes) pour lesquels on prouve : (i) des propriétés générales de chaînes extrémales, incluant la trivialité de la tribu queue, les corrélations à courtes portées, la réalisation via des limites à volumes infinis et l'ergodicité, (ii) deux nouvelles conditions pour l'unicité de la chaîne cohérente, (iii) des résultats de perte de mémoire et des propriétés de mélange pour des chaînes sous le régime de Dobrushin. On considère des systèmes à alphabet fini, pouvant avoir une grammaire. On établit

Resumen
The Critically Endangered Hainan gibbon (Nomascus hainanus) is the world’s rarest ape, with a single population of an estimated 25 individuals surviving in approximately 15 km² of suboptimal forest within Bawangling National Nature Reserve, Hainan, China. The existing biological evidence-base for the species is inadequate for conservation planning, precluding evaluation of appropriate recovery actions. I derived comprehensive new baseline data on Hainan gibbon ecology, behaviour and genetics to clarify the species’ biology and population status, and inform urgently required conservation manage
