1 2 3 4 5 |
X |
Matrix, possibly sparse of features. |
y |
Matrix of targets. |
lambdas |
Vector. Vector of L2 regularization parameters. |
maxiter |
Maximum number of iterations. |
w |
Matrix of weights. |
alpha |
constant step-size. Used only when fit_alg == "constant" |
stepSizeType |
scalar default is 1 to use 1/L, set to 2 to use 2/(L + n*myu). Only used when fit_alg="linesearch" |
Li |
Scalar or Matrix.Initial individual Lipschitz approximation. |
Lmax |
Initial global Lipschitz approximation. |
increasing |
Boolean. TRUE allows increase of Lipschitz coeffecient. False allows only decrease. |
d |
Initial approximation of cost function gradient. |
g |
Initial approximation of individual losses gradient. |
covered |
Matrix of covered samples. |
standardize |
Boolean. Scales the data if True |
tol |
Real. Miminal required approximate gradient norm before convergence. |
family |
One of "binomial", "gaussian", "exponential" or "poisson" |
fit_alg |
One of "constant", "linesearch" (default), or "adaptive". |
user_loss_function |
User supplied R or C loss and gradient functions |
... |
Any other pass-through parameters. |
