Isoelastic Agents and Wealth Updates in Machine Learning Markets

Recently, prediction markets have shown considerable promise for developing flexible mechanisms for machine learning. In this paper, agents with isoelastic utilities are considered. It is shown that the costs associated with homogeneous markets of agents with isoelastic utilities produce equilibrium prices corresponding to alpha-mixtures, with a particular form of mixing component relating to each agent's wealth. We also demonstrate that wealth accumulation for logarithmic and other isoelastic agents (through payoffs on prediction of training targets) can implement both Bayesian model updates and mixture weight updates by imposing different market payoff structures. An iterative algorithm is given for market equilibrium computation. We demonstrate that inhomogeneous markets of agents with isoelastic utilities outperform state of the art aggregate classifiers such as random forests, as well as single classifiers (neural networks, decision trees) on a number of machine learning benchmarks, and show that isoelastic combination methods are generally better than their logarithmic counterparts.Comment: Appears in Proceedings of the 29th International Conference on Machine Learning (ICML 2012

The Effects Of Organization Culture, Leadership And Job Motivation Upon The Employees Performance (Study At PT. Pln Educational And Training Center At Pasar Minggu, Jakarta Selatan)

The research consists of several steps that must be met in order to achieve results that meet the rules o fscientific research.Results of this study is expected to get ideas of the effect of the employee\u27s performance by organizational culture, leadership and motivation to work at PT.PLN (Persero) Education and Training Centre.The method used is quantitative method which examines four variables: three independent variables and one dependent variabel.The hypothesis testing at the 0.05 level with a population of more than 115 employees, the operational level.The result is that there is a direct effect of organizational culture on the performance of β41 = 0,459 with value tcalculate = 5,354 and ttable (α = 0,05) = 1,663 that mean is tcalculate > ttable (5,354 > 1,663). H0 is rejcted and H1 is accepted, which means the effect is significant.There is a direct effect of leadership on the performance of β42 = -0,007 with mean tcalculate = -0,080. and ttable (α = 0,05) = 1,663 wich mean tcalculate ttable (4,807 > 1,663), this H0 is rejected and H1 is accepted, which means the effect is significant.There is a direct effect of organizational culture on employee motivation at β31 = 0,474 which mean tcalculate = 5,508. and ttable (α = 0,05) = 1,663 yang berarti tcalculate > ttable (5,508 > 1,663), So that mean H0 is rejected and H1 is accepted, which means the effect is significant.There is a direct effect of leadership on job motivation for β32 = 0,389 which mean tcalculate = 4,520. and ttable (α = 0,05) = 1,663 that means tcalculate > ttable (4,520 > 1,663), so that mean H0 is rejected and H1 is accepted, which means the effect is significant.Based on the above it can be concluded that employee performance can be improved through organizational culture and work motivation

Real-life performance of protocol combinations for wireless sensor networks

Wireless sensor networks today are used for many and diverse applications like nature monitoring, or process and wireless building automation. However, due to the limited access to large testbeds and the lack of benchmarking standards, the real-life evaluation of network protocols and their combinations remains mostly unaddressed in current literature. To shed further light upon this matter, this paper presents a thorough experimental performance analysis of six protocol combinations for TinyOS. During these protocol assessments, our research showed that the real-life performance often differs substantially from the expectations. Moreover, we found that combining protocols is far from trivial, as individual network protocols may perform very different in combination with other protocols. The results of our research emphasize the necessity of a flexible generic benchmarking framework, powerful enough to evaluate and compare network protocols and their combinations in different use cases

The Effect of Marketing Mix Upon the Consumer's Decision Making to Buy a Product at PT. Griya Pagelaran Bogor,

The purpose of this study is to determine and prove whether the variablesof the marketing mix significantly has influenced the consumer's decision making tobuy the product at PT. Griya Pagelaran Bogor. The population of this study are thenumber of unknown sampling determination using Maximum Likelihood estimationmethod by taking samples of consumers who their needs has met with theresearcher requirement as many as 150 respondents. The analytical method hasused is Structural Equation Modeling (SEM) using AMOS 21 program. The result ofthe research shows that 1) Product Variables have a significance level of 0.05 whichis 1,965 > 1,96 and value (p) probability 0,49 ≤ 0.05. Then Ha is accepted andsignificant effect. 2) Variable Price level of significance 0.05 is 2.023 > 1.96 and hasa probability of 0.43 which is below 0.05. And the value (p) probability ≤ 0.05 then Hais accepted and significant effect. 3) Place Variables significance level of 0.05 is2.251 > 1.96 and has a probability of 0.24 which is below 0.05. And the value (p)probability ≤ 0.05 then Ha is accepted and significant effect. 4) Promotion Variables0.05 level of significance is 3.435 > 1.96 and has a probability in accordance with therecommended. And the value (p) probability ≤ 0.05 then Ha accepted and significanteffect

Pengembangan Pelumas Ramah Lingkungan dengan Ester Borat

This paper reports an attempt to improve the performance of environmentally friendly bio-based lube oil prepared from glycerol and oleic acid. Four variant of boric acid esters, fortified with 2,5dimercapto-1,3,4-thiadiazol, aromatic amine antioxidant, and benzotriazol were used as additives. The oxidation & corrosion test was carried out using the bulk test at 150oC for 24 h. Steel & copper specimens weight losses and kinematic viscosity increase (measured at 40oC and 100oC according to ASTM D-445) were used to measure the effect of formulation to the corrosiveness and oxidation stability of the oil, respectively. Experimental results indicated that nitrogen-containing boric acid esters showed better performance in terms of oxidation stability improvement. Slight increases in corrosiveness were shown for all additive systems. Phenyl-1-naphtylamine showed better performance than diphenylamine antioxidant
