Variation of Dimensional Manipulation. q That A and B are orthogonal is shown by the fact that theta is equal to /2. endobj Need better normalization than individually normalizing each vector otherwise every vector will converge to v 1. 0. This is especially troublesome as speed of teleportation may be too fast to control. Randomly varying the columns used to train each contributing member of the ensemble has the effect of introducing diversity into the ensemble and, in turn, can lift performance over using a single decision tree. v`l+oI(U FH7 Search .
