| Nov 18, 2013 at 15:19 | comment | added | rlbond | Also, what norm are you using? | |
| Nov 18, 2013 at 14:50 | comment | added | rlbond | I'm a little confused about that statement. Is $P_V$ a projection matrix? Is it an operator? How do you compute $P_V - P_W$? | |
| Nov 18, 2013 at 5:08 | comment | added | Qiaochu Yuan | How about $\| P_V - P_W \|$ where $P_V$ is the projection onto $V$? This is more of a distance and less of a similarity, but at least it's a reasonably canonical choice. | |
