WebThe Frank-Wolfe method is an alternative to Projected Gradient Descent which doesn’t involve projections. The Frank-Wolfe method is also known as conditional gradient method. Instead of using a quadratic ex-pansion as shown above for the projected GD method, it uses a local linear expansion of f. Note that if you were to apply projected …
