We report results from a human computation study that tests the extent to which output agreement games are better than traditional methods in terms of increasing quality of labels and motivation of voluntary workers on a task with a gold standard. We built an output agreement game that let workers recruited from Amazon’s Mechanical Turks label the semantic textual similarity of 20 sentence pair...

This paper reviews statistical methods for analyzing output data from computer simulations of single systems. In particular, it focuses on the problems of choosing initial conditions and estimating steady-state system parameters. The estimation techniques include the replication/deletion approach, the regenerative method, the batch means method, and the standardized time series method.

The aim of a probabilistic output analysis is to derive a probability distribution of possible output values for a program from a probability distribution of its input. We present a method for performing static output analysis, based on program transformation techniques. It generates a probability function as a possibly uncomputable expression in an intermediate language. This program is then a...

Deep neural networks (NN) are extensively used for machine learning tasks such as image classification, perception and control of autonomous systems. Increasingly, these deep NNs are also been deployed in high-assurance applications. Thus, there is a pressing need for developing techniques to verify neural networks to check whether certain user-expected properties are satisfied. In this paper, ...

Advanced statistical techniques are used to analyze Hong Kong output dynamics. Hong Kong, Japan and the U.S. are found to share some common long-term and short-term cyclical variations. While the Hong Kong economy is susceptible to external shocks and is “Granger-caused” by the other two economies, local factors account for a large proportion of output growth variability and are mainly responsi...

Evaluation of automatic translation output is a difficult task. Several performance measures like Word Error Rate, Position Independent Word Error Rate and the BLEU and NIST scores are widely use and provide a useful tool for comparing different systems and to evaluate improvements within a system. However the interpretation of all of these measures is not at all clear, and the identification o...

In these notes we describe how to measure the confidence we have in our Monte-Carlo estimates. In particular, we use he Central Limit Theorem to construct confidence intervals for the quantity we are truing to estimate. We also describe methods to estimate the number of samples that are required to achieve a given confidence level.

This paper concerns the statistical analysis of output from discrete-event computer simulations. In particular, we discuss problems involving terminating simulations, the initialization of simulations, steady-state point and confidence interval estimation for various system parameters, and comparison among competing system designs.

e xchange rate is an important factor influencing price indices of exported goods of a country in different ways. imported intermediate commodity is one of the important ways by which the change in exchange rate affects price indices of the exported goods. using the input-output table of iran for the year 2001, this paper investigates the impact of exchange rate devaluation on price indices of ...
