Class Solver

Parameters:

• type (str or int) - The solver type. One of the keys or values of the SOLVER_TYPES dict. If omitted or None, the default solver type is applied (L2R_L2LOSS_SVC_DUAL == 1)
• C (float) - Cost parameter, if omitted or None, it defaults to 1. C > 0.
• eps (float) - Tolerance of termination criterion. If omitted or None, a default is applied, depending on the solver type. eps > 0
• p (float) - Epsilon in loss function of epsilon-SVR. If omitted or None it defaults to 0.1. p >= 0.
• weights (mapping) - Iterator over label weights. This is either a dict, mapping labels to weights ({int: float, ...}) or an iterable of 2-tuples doing the same ([(int, float), ...]). If omitted or None, no weight is applied.
