   summary: "Update relevant entries in \'*var\' according to the Ftrl-proximal scheme."
   description: <<END
 That is for rows we have grad for, we update var, accum and linear as follows:
-accum_new = accum + grad * grad
-linear += grad + (accum_new^(-lr_power) - accum^(-lr_power)) / lr * var
-quadratic = 1.0 / (accum_new^(lr_power) * lr) + 2 * l2
-var = (sign(linear) * l1 - linear) / quadratic if |linear| > l1 else 0.0
-accum = accum_new
+$$accum_new = accum + grad * grad$$
+$$linear += grad + (accum_{new}^{-lr_{power}} - accum^{-lr_{power}} / lr * var$$
+$$quadratic = 1.0 / (accum_{new}^{lr_{power}} * lr) + 2 * l2$$
+$$var = (sign(linear) * l1 - linear) / quadratic\ if\ |linear| > l1\ else\ 0.0$$
+$$accum = accum_{new}$$
