two different methods of bayesian segmentation algorithm were used with different band combinations. sequential maximum a posteriori (smap) is a bayesian image segmentation algorithm which unlike the traditional maximum likelihood (ml) classification attempts to improve accuracy by taking contextual information into account, rather than classifying pixels separately. landsat 7 etm+ data with pa...

knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. the method, however, presents some deficiencies, including labor-intensive proced...

Millions of people search daily for movies, music, and books on the Internet. Unfortunately, non-personalized exploration of items can result in an infeasible number of costly interaction steps. We study the problem of efficient, repeated interactive search. In this problem, the user is navigated to the items of interest through a series of options and our objective is to learn a better search ...

Biography Dr. Dan Cornford is a lecture in Computer Science and works in the Neural Computing Research Group at Aston University. Research interests are in the field of spatial statistics, space-time modelling and data assimilation. Lehel Csato is a post-doc in the same group working on an EPSRC grant (GR/R61857/01) looking at applying sparse sequential Gaussian processes to data assimilation. ...

This paper studies an extended Bayesian Persuasion model in which multiple senders persuade one Receiver sequentially and the subsequent players can always observe previous signaling rules and their realizations. In the spirit of Harris (1985), I develop the recursive concavification method to characterize the Subgame Perfect Equilibrium, which summarizes the multiplicity of possible strategic ...

This paper studies a Bayesian Persuasion model in which multiple senders sequentially persuade one Receiver. Players can always observe signaling rules of prior players and their realizations. I develop a recursive concavification method to characterize the set of SPEa. I prove the existence of a special type of equilibrium, called the Silent Equilibrium, where at most one sender designs a nont...

Sequential change diagnosis is the joint problem of detection and identification of a sudden and unobservable change in the distribution of a random sequence. In this problem, the common probability law of a sequence of i.i.d. random variables suddenly changes at some disorder time to one of finitely many alternatives. This disorder time marks the start of a new regime, whose fingerprint is the...

Assume that at the beginning of game t, the system's belief in the user's preference is P t. Then, the certainty-equivalet user preference during game t is π * t (i) = E π∼Pt [π(i)] ∀i ∈ I. Recall we define π * min = min i∈I π * (i), Lemma A-1 formalizes the result that if π * t is " close " to π * , then for any decision tree T , E i∼π * t [N (T, i)] is " close " to E i∼π * [N (T, i)]: Lemma A...
