A class for optimizing budget allocation in a marketing mix model.
The goal of this optimization is to maximize the total expected response by allocating the given budget across different marketing channels. The optimization is performed using the Sequential Least Squares Quadratic Programming (SLSQP) method, which is a gradient-based optimization algorithm suitable for solving constrained optimization problems.
For more information on the SLSQP algorithm, refer to the documentation: https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.minimize.html
- Parameters:
- num_periods
int
Number of time units at the desired time granularity to allocate budget for.
- model
MMMModel
The marketing mix model to optimize.
- response_variable
str
, optional The response variable to optimize. Default is “total_contribution”.
- utility_function
UtilityFunctionType
, optional The utility function to maximize. Default is the mean of the response distribution.
- budgets_to_optimize
xarray.DataArray
, optional Mask defining a subset of budgets to optimize. Non-optimized budgets remain fixed at 0.
- custom_constraints
Sequence
[Constraint
], optional Custom constraints for the optimizer.
- default_constraintsbool, optional
Whether to add a default sum constraint on the total budget. Default is True.
- num_periods
