We propose the adoption of a vector extrapolation technique to accelerate convergence of correspondence problems under the quadratic assignment formulation for attributed graph matching (QAP). In order to capture a broad range of matching scenarios, we provide a class of relaxations of the QAP under elastic net constraints. This allows us to regulate the sparsity/complexity trade-off which is i...

We present results of a large-scale simulation for the Kaon B parameter BK in quenched lattice QCD with the Kogut-Susskind quark action. Calculating BK at 1% statistical accuracy for seven values of lattice spacing in the range a ≈ 0.24 − 0.04 fm on lattices up to 563 × 96, we verify a quadratic a dependence of BK theoretically predicted. Strong indications are found that, with our level of acc...

We investigate in this paper the numerical performances of quadratic functional quantization with some applications to Finance. We emphasize the rôle played by the so-called product quantizers and the Karhunen-Loève expansion of Gaussian processes, in particular the Brownian motion. We show how to build some efficient functional quantizers for Brownian diffusions. We propose a quadrature formul...

It is well understood that in ADAS applications, a good estimate of the pose vehicle required. This paper proposes metaphorically named 2.5D odometry, whereby planar odometry derived from yaw rate sensor and four wheel speed sensors augmented by linear model suspension. While core already literature, this fitting quadratic to incoming signals, enabling interpolation, extrapolation, finer integr...

Extrapolation is a well-known numerical technique for raising the approximation order. Several variants of extrapolation can be used for elliptic partial diierential equations. The basic algorithmic variants are Richardson extrapolation, truncation error extrapolation and extrapolation of the functional. In multi-dimensional problems the error can be expanded into multivariate polynomials with ...

Noncentral indefinite quadratic expressions in possibly non- singular normal vectors are represented in terms of the difference of two positive definite quadratic forms and an independently distributed linear combination of standard normal random variables. This result also ap- plies to quadratic forms in singular normal vectors for which no general representation is currently available. The ...

In this paper, first the limitations of the ray-based method and the one-way wave-field extrapolation migration (WEM) in imaging steeply dipping structures are discussed by some examples. Then a new method of the reverse time migration (RTM), used in imaging such complex structures is presented. The proposed method uses a new wave-field extrapolator called the Leapfrog-Rapid Expansion Method (L...

Fredrich Froebel was a scientist, both in instinct and training, his life coincided with an important dynamic period of scientific growth. I take this opportunity to delve into some history futurology examine the heritage legacy work. The usual interpolation is reading data: where there exist consistent trends within broad set data then reader can reasonably infer value intervening points, ‘rea...
