  "Description": "A small multilayer perceptron implementation for 'R'. It\nsupports regression and classification, multiple hidden layers,\nmini-batch training, adaptive moment estimation, stochastic\ngradient descent, momentum, Nesterov acceleration, resilient\nbackpropagation and limited-memory quasi-Newton optimization,\ndropout, squared-weight regularization, early stopping,\nconvergence thresholds, gradient clipping, sample and class\nweights, callback hooks, target scaling and robust Huber loss\nfor regression, 'Rcpp' forward-pass kernels, formula\ninterfaces, model evaluation with balanced classification\nmetrics, cross-validation, compact tuning, permutation\nimportance, model persistence helpers, and standard prediction\nmethods. Methods follow Rumelhart, Hinton and Williams (1986)\n<doi:10.1038/323533a0>, with optimizers including Riedmiller\nand Braun (1993) <doi:10.1109/ICNN.1993.298623>, Nocedal (1980)\n<doi:10.1090/S0025-5718-1980-0572855-7>, and Kingma and Ba\n(2014) <doi:10.48550/arXiv.1412.6980>.",
