WitrynaOnce a tree has been snedded, cross cut into logs of whatever size is required. It is usually easiest to start at the tip where the tree is lightest. Support the tree so the cuts will open as you saw. When cutting logs, balance them on another trunk. This gives straight logs for stacking or making cords. WitrynaA standard approach is to scale the inputs to have mean 0 and a variance of 1. Also linear decorrelation/whitening/pca helps a lot.
