摘要:By simulating the easy-to-hard learning manners of humans/animals, the learning regimes called curriculum learning (CL) and self-paced learning (SPL) have been recently investigated and invoked broad interests. However, the intrinsic mechanism for analyzing why such learning regi...

摘要:Over past few decades, numerous machine learning algorithms have been developed for solving various problems arising in practical applications. And, loss function is one of the most significant factors influencing the performance of algorithm. Nevertheless, most readers may be co...

摘要:Learning high-quality phrase vector representations is one of important research topics in statistical machine translation (SMT). Towards phrase embeddings, most existing works mainly explore syntactic and semantic clues among internal words within phrases, which are however insu...

摘要:We consider the Helmholtz equation with a complex attenuation coefficient on a bounded, strictly convex domain in $\mathbb{R}^d$. We prove a Hölder conditional stability estimate for identifying attenuation coefficients from phaseless boundary value measurements, when the in...

摘要:We study a stochastic particle system with a logarithmically-singular inter-particle interaction potential which allows for inelastic particle collisions. We relate the squared Bessel process to the evolution of localized clusters of particles, and develop a numerical method...

摘要:We investigate a class of aggregation-diffusion equations with strongly singular kernels and weak (fractional) dissipation in the presence of an incompressible flow. Without the flow the equations are supercritical in the sense that the tendency to concentrate dominates the ...

摘要:In this paper, we study the quasi-neutral limit of the full quantum Navier–Stokes–Maxwell equation as the Debye length tends to zero. We justify rigorously the quasi-neutral limit by establishing rigorous uniform estimates on the error functions with respect to the Debye len...

摘要:Dislocations are the main carriers of the permanent deformation of crystals. For simulations of engineering applications, continuum models where material microstructures are represented by continuous density distributions of dislocations are preferred. It is challenging to captur...

摘要:We address the far field regularity for solutions of the surface quasi-geostrophic equation \[ \begin{array} & \theta_t + u \cdot \nabla \theta + \Lambda^{2 \alpha} \theta = 0 \\ u=\mathcal{R}^{\perp} \theta = (- \mathcal{R}_2 \theta , \mathcal{R}_1 \theta) \end{array} \] in the ...

摘要:We consider here a Fokker–Planck equation with variable coefficient of diffusion which appears in the modeling of the wealth distribution in a multi-agent society. At difference with previous studies, to describe a society in which agents can have debts, we allow the wealth ...
