Small mistakes corrected and added a vignette for doing hyper-parameter tuning with nntrf and mlr
nntrf 0.1.2
Mistake corrected in hyper-parameter tuning vignette. Added Xavier and orthogonal weight initialization.
nntrf 0.1.3
Removed Xavier and orthogonal initialization methods (they do not seem to improve results and make code more complex). Regression problems are now allowed, and a new vignette has been added for regression.
