  "Description": "Fit a predictive model using iteratively reweighted\nboosting (IRBoost) to minimize robust loss functions within the\nCC-family (concave-convex). This constitutes an application of\niteratively reweighted convex optimization (IRCO), where convex\noptimization is performed using the functional descent boosting\nalgorithm. IRBoost assigns weights to facilitate outlier\nidentification. Applications include robust generalized linear\nmodels and robust accelerated failure time models.
