Abstract. This paper presents a new approach to online multi-class learning with bandit feedback. This algorithm, named PAB (Passive Aggressive in Bandit) is a variant of Online Passive-Aggressive Algorithm proposed by [2], the latter being an e↵ective framework for performing max-margin online learning. We analyze some of its operating principles, and show it to provide a good and scalable sol...
DX dipoles, with an aperture of 18 cm, are located on each side of the six intersection regions of RHIC. All DX dipoles were tested at 4.35 K for quench performance, and trained successfully to at least a 10% margin above the operating field (4.3 T at 6.6 kA). Field quality in these dipoles was measured at room temperature and at 4.35 K using a rotating coil system. The measured harmonics were ...
We reassess the predictability of U.S. recessions at horizons from three months to two years ahead for a large number of previously proposed leading-indicator variables. We employ an efficient probit estimator for partially missing data and assess relative model performance based on the receiver operating characteristic (ROC) curve. While the Treasury term spread has the highest predictive powe...
Some aspects of bank strategic management are defined in the article. Efficiency econometric modelling one leading banks operating at Ukrainian financial market was performed using Statistica and Excel PCs. To establish appropriate correlations, three inputs that were most affected during coronavirus pandemic identified: net interest margin, leverage ratio, profitability personnel costs. There ...
A new algorithm for on-line learning linear-threshold functions is proposed which efficiently combines second-order statistics about the data with the ”logarithmic behavior” of multiplicative/dual-norm algorithms. An initial theoretical analysis is provided suggesting that our algorithm might be viewed as a standard Perceptron algorithm operating on a transformed sequence of examples with impro...
During this year, the configuration of the ring has been defined (cell structure, periodicity, superperiodicity, length of the straight sections). A large number of operating points have been studied to reach, with a fair safety margin, the project's required performances. Special attention was paid to optimizing energy acceptance up to ± 4 %, leading to a maximized beam lifetime even at very h...
BACKGROUND AND PURPOSE Hematoma expansion in intracerebral hemorrhage is associated with higher morbidity and mortality. The computed tomography (CT) angiographic spot sign is highly predictive of expansion, but other morphological features of intracerebral hemorrhage such as fluid levels, density heterogeneity, and margin irregularity may also predict expansion, particularly in centres where C...
This paper presents a validation framework for collateral requirements or margins on a derivatives exchange. It can be used by investors, risk managers, and regulators to check the accuracy of a margining system. The statistical tests presented in this study are based either on the number, frequency, magnitude, or timing of margin exceedances, which are de ned as situations in which the trading...
In this communication, hexapod tripod gaits for straightline motion and crab walking are derived. Mathematical relations that express the stability margin, the stride length, and the duty factor are formulated for straight-line motion and for crab walking, respectively. The derived results provide tripod gaits of the hexapod for walking with a prescribed stability margin either over perfect ter...
Since 2000, Menlo Worldwide Forwarding (formerly Emery Worldwide) has faced a particularly challenging business environment that has been exacerbated by a weakened economy, the events of September 11, and a decreasing demand for airfreight. To meet these challenges, the company and Menlo Worldwide Technologies developed a network-routing-optimization model to optimize Menlo Worldwide Forwarding...
