Linear and Logistic Regression ==== * input format: LibSVM * Example: [run-linear.sh](run-linear.sh) Parameters === All the parameters can be set by param=value #### Important Parameters * objective [default = logistic] - can be linear or logistic * base_score [default = 0.5] - global bias, recommended set to mean value of label * reg_L1 [default = 0] - l1 regularization co-efficient * reg_L2 [default = 1] - l2 regularization co-efficient * lbfgs_stop_tol [default = 1e-5] - relative tolerance level of loss reduction with respect to initial loss * max_lbfgs_iter [default = 500] - maximum number of lbfgs iterations ### Optimization Related parameters * min_lbfgs_iter [default = 5] - minimum number of lbfgs iterations * max_linesearch_iter [default = 100] - maximum number of iterations in linesearch * linesearch_c1 [default = 1e-4] - c1 co-efficient in backoff linesearch * linesarch_backoff [default = 0.5] - backoff ratio in linesearch
