In this paper they propose two ways to deal with the imbalanced data classification problem using random forest. One is based on cost sensitive learning, and the other is based on a sampling technique. Performance metrics such as precision and recall, false positive rate and false negative rate, F-measure and...
A traffic performance measurement system, PeMS, currently functions as a statewide repository for traffic data gathered by thousands of automatic sensors. It has integrated data collection, processing, and communications infrastructure with data storage and analytical tools. In this paper, they discuss statistical issues that have emerged as we attempt to...
Sparse approximations to Bayesian inference for nonparametric Gaussian Process models scale linearly in the number of training points, allowing for the application of these powerful kernel-based models to large datasets. We show how to generalize the binary classification informative vector machine IVM to multiple classes. In contrast to earlier efficient...
This report describes the results of accelerated pavement tests on full-scale pavements with "wet" base conditions at the Pavement Research Center, located at the University of California Berkeley Richmond Field Station RFS. The report contains a summary of the results and associated analysis of a pavement section comprised of three...
Construction planning is a complex process that involves coordination between many project participants on- and off-site. As projects have been increasing in size and complexity, the number of participants involved in a single project has also increased. This research presents a Distributed Planning and Control (DP&C) method based on a...
This paper proposes a Fisher Efficient estimator in the model of independent component analysis ICA. First, it provides a n-consistent estimator using the empirical characteristic function, and then, shows that by directly estimating the efficient influence function, we can construct a one-step maximum likelihood estimate MLE which reaches asymptotic Fisher...
- John Robbins, a founder of Carpenter/Robbins Commercial Real Estate Inc. in San Ramon, has been named to the University of California, Berkeley's Lawrence Hall of Science advisory council. The council serves as an adviser to the Lawrence Hall of Science in fundraising, committee work and business development. ...
