A vast majority of L1 vocabulary acquisition occurs through incidental learning during reading (Nation, 2001; Schmitt et al., 2001). We propose a probabilistic approach to generating code-mixed text as an L2 technique for increasing retention in adult lexical learning through reading. Our model that takes as input a bilingual dictionary and an English text, and generates a code-switched text th...
Deep metric learning aims to learn a feature space that models the similarity between images, and normalization is critical step for boosting performance. However directly optimizing L2-normalized softmax loss cause network fail converge. Therefore some SOTA approaches appends scale layer after inner product relieve convergence problem, but it incurs new problem it's difficult best scaling para...
Cheeger, Goresky, and MacPherson conjectured [CGM] an L2-de Rham theorem: that the intersection cohomology of a projective variety V is naturally isomorphic to the L2cohomology of the incomplete manifold V − Sing V , with metric induced by a projective embedding. The early interest in this conjecture was motivated in large part by the hope that one could then put a Hodge structure on the inters...
Given a non-negative n × m real matrix A, the matrix scaling problem is to determine if it is possible to scale the rows and columns so that each row and each column sums to a specified target value for it. The matrix scaling problem arises in many algorithmic applications, perhaps most notably as a preconditioning step in solving linear system of equations. One of the most natural and by now c...
This paper relates the boundary term in the Chern-Gauss-Bonnet formula on 4-manifolds M with the renormalized volume V , as defined in the AdS/CFT correspondence, for asymptotically hyperbolic Einstein metrics on M . In addition we compute and discuss the differential or variation dV of V , or equivalently the variation of the L norm of the Weyl curvature, on the space of such Einstein metrics....
A chromophore in which zinc porphyrin donors are linked through their meso positions by ethynyl bridges to a bis(indolinylidenemethyl) squaraine core has been synthesized using Sonogashira coupling. The chromophore exhibits a two-photon absorption spectrum characterized by a peak cross section of 11,000 GM and, more unusually, also exhibits a large cross section of >780 GM over a photon-wavelen...
We study integral curvature conditions for a Riemannian metric g on S4 that quantify the best bilipschitz constant between (S4,g) and standard S4. Our results show is controlled by L2-norm of Weyl tensor L1-norm Q-curvature, under those quantities are sufficiently small, has positive Yamabe Q-curvature mean-positive. The proof result achieved in two steps. Firstly, we construct quasiconformal m...
When handling fuzzy number data, it is a common practice to make use of a metric to quantify distances between fuzzy numbers. Several metrics have been suggested in the literature for this purpose. When statistically analyzing fuzzy number-valued data, L metrics become especially useful. This paper introduces a new family of generalized L metrics which take into account key features of the invo...
تبخیر و تعرق یکی از مولفه های مهم در چرخه هیدرولوژی و از عوامل تعیین کننده معادلات انرژی در سطح زمین و توازن آب می باشد و برآورد آن در زمینه های مختلف علوم مانند هیدرولوژی، کشاورزی، جنگل و مرتع و مدیریت منابع آب مورد نیاز است. روش های متداول بر آورد تبخیر و تعرق از اندازه گیری های نقطه ای استفاده کرده و لذا فقط برای مناطق و محدوده های محلی مناسب بوده و به مناطق بزرگ تر و حوضه های آبخیز قابل تعم...
Given a compact metric space X and a strictly positive Borel measure ν on X , Mercer’s classical theorem states that the spectral decomposition of a positive self-adjoint integral operator Tk : L2(ν) → L2(ν) of a continuous k yields a series representation of k in terms of the eigenvalues and -functions of Tk. An immediate consequence of this representation is that k is a (reproducing) kernel a...
