loss function summing over regions and data points

Defining Formula: $\ell (\sigma )\equiv \sum _{i=1}^{N_T}\sum _{m=1}^{N_R}\frac{({\omega }_{m,t_i}-\varphi (t_i|\sigma ,{\omega }_{\bullet ,0}){)}^2}{C_{m,t_i}^2}$

$N_R$ symbol represents Number of Regions

$\varphi$ symbol represents Spreading Curve (Approximate)

$\sigma$ symbol represents Contact Network (Time-dependent)

$C$ symbol represents Weight Factor

$N_T$ symbol represents Number of Time Points

$\omega$ symbol represents Romanized Cities Vector

$t_i$ symbol represents Time Point

$\ell$ symbol represents Loss Function (Romanization)
