This paper presents a new approach to discrete choice analysis for risky prospects. Conventional discrete choice analysis focuses on riskless prospects and does not deal with the scenario where the alternatives that the decision-makers choose from are associated with risk. In this paper, we investigate decisionmakers’ risk perception and choice behaviour in choice experiments when they are faci...

The context-tree weighting algorithm [4] is a universal source coding algorithm for binary tree sources. In [2] the algorithm is modified for byte-oriented tree sources. This paper describes the context-tree branch-weighting algorithm, which can reduce the number of parameters for such sources, without increasing the complexity significantly.

The CHaracteristic-function-Enabled Source Separation (CHESS) method for independent component analysis (ICA) is based on approximate joint diagonalization (AJD) of Hessians of the observations’ empirical log-characteristicfunction, taken at selected off-origin “processing points”. As previously observed in other contexts, the AJD performance can be significantly improved by optimal weighting, ...

Microwave sounders have been used for many years to measure the thermodynamic state of the atmosphere, i.e. the three-dimensional distribution of temperature, water vapor and liquid water, both from space, from aircraft and from the ground. Currently, the most advanced satellite based microwave sounding system is the Advanced Microwave Sounding Unit (AMSU-A and-B) operating on a number of weath...

optimal attributes are useful in interpretation of seismic data. two proposed methods are presented in this paper for finding optimal attributes. regularized discriminate analysis(rda) is based on 2 parameters ë, ? which called regularization parameter. the other method is principal component analysi s(pca).in this paper gas chimney detection is defined as the subject of study for ranking relev...

This study proposed a weighting function for a dynamic (DP) programming approach as the cost function to handle beat tracking. The function is utilized to adapt bandwidth of tempo deviation which reciprocal represents likelihood of relative beat position. The beat tracking surpass those scores of other algorithms for MAZ dataset, in which seven out of ten performance indexes outperforms in MIRE...

Recently, much excitement has been caused in the EUPAS group by the evaluation of the IEEE 1241 draft standard. This draft contains a lot of useful information and several well established facts. However, there are also some details which are not fully clarified, or need further examination. This paper deals with one of these: the possibility of data processing, based on windowed data.
