Let $O_{N,5}$ be the optimized model with approximation order $N$ and entropy-approximation parameter $5$, optimized on the interval $[-5,5]$. Let $O_5(x)$ denote the corresponding…

Let $O_{2K+1}$ denote the optimized polynomial approximation model of degree $2K+1$, and let $\beta_{BS}$ denote the Boltzmann–Shannon entropy function. Fix an interval of the real…

Moment-reconstruction-error conjecture. The moment reconstruction error $E_{\bw}$ would be a more reliable measure for closure accuracy than the multiplier error $E_{\bsalpha}$. Th…

Consider the Markovian SIR model with transmission rate $\tau$ and recovery rate $\gamma$, so that $\tau/\gamma$ is the only dimensionless parameter. Inverse-rate scaling conjectur…
