learning_rate
:
string,
optional,
default = ‘optimal’
If learning rate is ‘constant’, eta = eta0;
If learning rate is ‘optimal’, eta = 1.0/(alpha*(t+t0)), where t0 is
chosen by Leon Bottou;
If learning rate = ‘invscalling’, eta = eta0/pow(t, power_t).
If learning rate = ‘adaptive’, eta = eta0.
eta0
:
double,
default = 0.0
It represents the initial learning rate for above mentioned learning rate
options i.e. ‘constant’, ‘invscalling’, or ‘adaptive’.
