The ADAM Algorithm for gMIC Optimization (experimental)
1 2 |
X |
Design matrix. |
y |
The response vector. |
a |
The approximation parameter for gMIC. |
lambda |
The penalization parameter for gMIC, e.g., 2 for AIC and long(n) for BIC. |
gamma |
The optimization parameter gamma. |
group |
The group structure of the model. For example, assume that X has 4 columns and group=c(1,1,2,2). It means the first 2 features form a group of variables and the last 2 features form another group of variables. |
family |
The type of glm model, should be one of "gaussian", "binomial" or "poisson". |
stepsize |
Stepsize for group coordinate descent. |
tol |
Convergence tolerance. |
maxit |
Maximum number of iterations. |
b1 |
ADAM hyperparameter, default is 0.9. |
b2 |
ADAM hyperparameter, default is 0.999. |
e |
ADAM hyperparameter, default is to 1e-8. |
