Estimating dynamic transmission rates with a Black-Karasinski process in stochastic SIHR models using particle MCMC
Compartmental models are effective in modeling the spread of infectious pathogens, but have remaining weaknesses in fitting to real datasets exhibiting stochastic effects. We propose a stochastic SIHR model with a dynamic transmission rate, where the rate is modeled by the Black-Karasinski (BK) process - a mean-reverting stochastic process with a stable equilibrium distribution, making it well-suited for modeling long-term epidemic dynamics. To generate sample paths of the BK process and estima…

Forward Reverse Kernel Regression for the Schrödinger bridge problem
In this paper, we study the Schrödinger Bridge Problem (SBP), which is central to entropic optimal transport. For general reference processes and begin--endpoint distributions, we propose a forward-reverse iterative Monte Carlo procedure to approximate the Schrödinger potentials in a nonparametric way. In particular, we use kernel based Monte Carlo regression in the context of Picard iteration of a corresponding fixed point problem. By preserving in the iteration positivity and contractivity …

Quantum Meets SAR: A Novel Range-Doppler Algorithm for Next-Gen Earth Observation
Synthetic Aperture Radar (SAR) plays a vital role in remote sensing due to its ability to capture high-resolution images regardless of weather conditions or daylight. However, to transform the raw SAR signals into interpretable imagery, advanced data processing techniques are essential. A widely used technique for this purpose is the Range Doppler Algorithm (RDA), which takes advantage of Fast Fourier Transform (FFT) to convert signals into the frequency domain for further processing. However, …

product_space: Atlas of Economic Complexity export network
Two networks of economic products, where a pair of products are connected if they are exported at similar rates by the same countries. The data are a projection from a bipartite network of nations and the products they export. Edges weights represent a similarity score (called "proximity"). Data based on UN Comtrade worldwide trade patterns. SITC network based on the Standard International Trade Classification and HS …

Error Estimates for the Arnoldi Approximation of a Matrix Square Root
The Arnoldi process provides an efficient framework for approximating functions of a matrix applied to a vector, i.e., of the form $f(M)\mathbf{b}$, by repeated matrix-vector multiplications. In this paper, we derive an \textit{a priori} error estimate for approximating the action of a matrix square root using the Arnoldi process, where the integral representation of the error is reformulated in terms of the error for solving the linear system $M\mathbf{x}=\mathbf{b}$. The results extend the er…

Selv om jeg faktisk var medlem i Piratpartiet en periode, ser jeg nå hvor begrenset prosjektet egentlig er fra et anarkistisk perspektiv. Piratpartiet snakker mye om åpenhet, personvern og digital frihet, men de er fortsatt bundet til det parlamentariske spillet. De sŸker makt gjennom valg, partier og representasjon, akkurat som alle andre.
De vil reformere systemet innenfra, men det er nettopp systemet som er problemet. Ekte frihet og selvstyre kan ikke oppnås gjennom Stortinget eller…
