In practice, it is often necessary to combine information from different sources. For this task, one of aggregation operators can be used. Probably the best-known of them are the weighted average and the OWA (ordered weighted average) operator. The weighted average makes it possible to assign importances to the individual information sources. On the other hand, with the OWA operator, the import...

In the first part of this lecture, we analyze the noise sensitivity of the Majority function in more detail than last time. In the second part, we discuss the Majority is Stablest theorem, which says that among balanced functions for which each of the individual variables has low influence, the Majority function has the lowest noise sensitivity up to some small error. We also see some applicati...

We describe the problem of decision making under ignorance and discuss the need of introducing a decision attitude or disposition in solving this problem. We show the OWA operators provide a general framework for evaluating the alternatives when the payoffs are numeric values. We then turn to the problem of decision making when the payoffs are linguistic values drawn from an ordinal scale. A so...

We present a novel multi-modal evidence fusion method for highlevel feature (HLF) detection in videos. The uni-modal features, such as color histogram, transcript texts, etc, tend to capture different aspects of HLFs and hence share complementariness and redundancy in modeling the contents of such HLFs. We argue that such inter-relation are key to effective multi-modal fusion. Here, we formulat...

Cell-based Multicriteria Evaluation (MCE) methods are used to analyse the land suitability evaluation. Land evaluation is carried out to estimate the suitability of land for a specific use such as arable farming or irrigated agriculture. land suitability evaluation is a prerequisite for land-use planning and development (Sys 1985; Van Ranst and others 1996). It provides information on the const...

Biomedical signal monitoring and recording are an integral part of medical diagnosis treatment control mechanisms. For this, enhanced signals with appropriate peak preservation required. The OWA (OrderedWeighted Aggregation) Filter used in this paper helps non-linear filtering peaks for accurate diagnosis. Weights important aspect the filter, Gaussian method KDE (Kernel Density Estimation) func...

This study aims at determining the elemental concentrations of Cu, Zn, Cr, Pb, Ni, Co and Cd in the sediment samples from Odo-Owa and Yemoji streams in Ijebu-Ode Local Government Area (L.G.A), South Western (SW) Nigeria, using Atomic Absorption Spectrophotometer and comparing the concentration of these metals in the two streams with other studies and with acceptable concentration values for met...

The wireless industry is rapidly transitioning from proprietary architecture to more flexible, cost effective open wireless architecture (OWA) systems. This transition is creating interesting challenges for developers, manufacturers, integrators, operators and end-users as they wrestle with complexities of open wireless systems. Fourth Generation (4G) Mobile Communications should not focus only...

The standard epistemic justification for inclusiveness in political decision making is the Condorcet Jury Theorem, which states that the probability of a correct decision using majority rule increases in group size (given certain assumptions). Informally, majority rule acts as a mechanism to pool the information contained in the judgements of individual agents. I aim to extend the explanation o...
