Learning with Mandelbrot and Julia
V. R. Tjahjono, S. F. Feng, E. R. M. Putri +1
Recent developments in applied mathematics increasingly employ machine learning (ML)-particularly supervised learning-to accelerate numerical computations, such as solving nonlinea…
How many can you infect? Simple (and naive) methods of estimating the reproduction number
H. Susanto, V. R. Tjahjono, A. Hasan +5
This is a pedagogical paper on estimating the number of people that can be infected by one infectious person during an epidemic outbreak, known as the reproduction number. Knowing…
A new estimation method for COVID-19 time-varying reproduction number using active cases
A. Hasan, H. Susanto, V. R. Tjahjono +4
We propose a new method to estimate the time-varying effective (or instantaneous) reproduction number of the novel coronavirus disease (COVID-19). The method is based on a discrete…
Snakes and ghosts in a parity-time-symmetric chain of dimers
H. Susanto, R. Kusdiantara, N. Li +4
We consider linearly coupled discrete nonlinear Schrödinger equations with gain and loss terms and with a cubic-quintic nonlinearity. The system models a parity-time ()-s…
