Boosting the margin: A new explanation for the effectiveness of voting methods
- IN PROCEEDINGS INTERNATIONAL CONFERENCE ON MACHINE LEARNING
, 1997
"... One of the surprising recurring phenomena observed in experiments with boosting is that the test error of the generated classifier usually does not increase as its size becomes very large, and often is observed to decrease even after the training error reaches zero. In this paper, we show that this ..."

The effect of national culture on the choice of entry mode
- Journal of International Business Studies
, 1988
"... Abstract. Characteristics of national cultures have frequently been claimed to influence the selection of entry modes. This article investigates this claim by developing a theoretical argument for why culture should influence the choice of entry. Two hypotheses are derived which relate culture to en ..."

, wholly owned greenfield, and joint venture. Empirical support for the effect of national culture on entry choice is found. Foreign direct investment into the United States has grown dramatically since the early 1970s. Accompanying this increase has been a growth of academic work studying the phenomenon.1
Split States, Entropy Enigmas, Holes and Halos
, 2007
"... We investigate degeneracies of BPS states of D-branes on compact Calabi-Yau manifolds. We develop a factorization formula for BPS indices using attractor flow trees associated to multicentered black hole bound states. This enables us to study background dependence of the BPS spectrum, to compute e ..."

We point out a likely breakdown of the OSV conjecture at small gtop (in the large background CY volume limit), due to the surprising phenomenon that for sufficiently large background Kähler moduli, a charge ΛΓ supporting single centered black holes
Surprising Harmonies
, 1999
"... Understanding surprise is a key to the cognition of music, at all levels of musical structure: rhythm, melody, harmony, timbre. This paper addresses the modeling of surprise in particular music sequences: Jazz harmonic progressions. Most of the works in music cognition relate surprise to the phenome ..."

to the phenomenon of musical expectation: a surprise is seen as something unexpected. Furthermore, unexpected more or less means "unheard before". In this paper, we emphasize the importance of the rich algebraic structure underlying Jazz chord sequences, and suggest that harmonic surprise may not only
Earnings surprises, growth expectations, and stock returns or don’t let an earnings torpedo sink your portfolio. Working Paper
, 1999
"... It is well established that the realized returns of ‘growth ’ stocks have been low relative to other stocks. We show that this phenomenon is explained by a large and asymmetric response to negative earnings surprises for growth stocks. After controlling for this effect, there is no longer evidence o ..."

The Power of Testing Memory -- Basic Research and Implications for Educational Practice
-
, 2006
"... A powerful way of improving one’s memory for material is to be tested on that material. Tests enhance later retention more than additional study of the material, even when tests are given without feedback. This surprising phenomenon is called the testing effect, and although it has been studied by c ..."

Surprises in aperiodic diffraction

"... Abstract. Mathematical diffraction theory is concerned with the diffraction image of a given structure and the corresponding inverse problem of structure determination. In recent years, the understanding of systems with continuous and mixed spectra has improved considerably. Moreover, the phenomenon ..."

Secrets of Optical Flow Estimation and Their Principles
, 2010
"... The accuracy of optical flow estimation algorithms has been improving steadily as evidenced by results on the Middlebury optical flow benchmark. The typical formulation, however, has changed little since the work of Horn and Schunck. We attempt to uncover what has made recent advances possible throu ..."

through a thorough analysis of how the objective function, the optimization method, and modern implementation practices influence accuracy. We discover that “classical” flow formulations perform surprisingly well when combined with modern optimization and implementation techniques. Moreover, we find
Regaining our capacity for surprise

. • Microbiologists who are not computationally inclined – the vast majority – are therefore confronted with difficult choices as to how to pursue a phenomenon with the same zeal and creativity as before the age of mass bioinformation. • We must develop more intelligent interfaces between humans and bioinformation so
The Surprising Crab Nebula
"... We will present our study of the flux and spectral variability of the Crab above 100 MeV on different timescales ranging from days to weeks. In addition to the four main intense and day-long flares detected by AGILE and Fermi-LAT between Sept. 2007 and Sept. 2012, we find evidence for week-long and ..."

Most likely, flares and waves are the product of the same class of plasma
