WebbThe SVM optimization problem can also be solved with lagrange multipliers. ... The reason we would transform the problem in this way is that it allows us to leverage some extremely powerful mathematical techniques. In jargon, we say that the lagrange multiplier solution to the SVM optimization problem re-states the problem in a dual form. Webb10 apr. 2024 · Simplest means you know the answer (or are closer to that answer). After that, simplest means this sub-problem being solved doesn’t depend on others being solved. Once you solved every sub-problem, connect the dots. Connecting all your “sub-solutions” will give you the solution to the original problem.
