FWMode

class paminco.optim.fw.FWMode(value)

Enum defining the update mode of the FW solver.

Possible modes:

STEP_SIZE_DETERIATION

solution is updated as \(\mathbf{x}_{i+1} = (1-\eta)*\mathbf{x}_{i} + \eta * \mathbf{s}_i\) where \(\eta = \frac{2}{2+i}\).

LINESEARCH

solution is updated as \(\mathbf{x}_{i+1} = (1-\eta)*\mathbf{x}_{i} + \eta * \mathbf{s}_i\) where \(\eta\) is found by minimizing \(f\) on a line between \(\mathbf{x}_i\) and \(\mathbf{s}_i\).
