| 13:31.06 | hippieindamakin8 | brlcad, havent registered for summer school. i took up a summer job |
| 13:31.23 | brlcad | anything technical/interesting? |

| 13:34.33 | hippieindamakin8 | and then probably we ll be using a beagleboard and a screen to develop a handheld |
| 13:35.37 | hippieindamakin8 | apart from that a literature study at the university with a prof on the geometric coresets and their applications |
| 13:35.53 | brlcad | coresets? |
| 13:36.34 | _clock_ | corsets? |
| 13:37.05 | hippieindamakin8 | coresets are this geometric approximations we work on . they are the subsets of the actual sets with an /epsilon error |
| 13:37.16 | brlcad | eh? |
| 13:38.18 | brlcad | you've still not said what that means :) |
| 13:38.33 | brlcad | .. coresets are geometric approximations (of what?) |
| 13:38.35 | hippieindamakin8 | suppose we have a clustering problem, and the point set is very huge, now we develop a coreset which is an approximation of the point set and then using this coreset we obtain we get |
| 13:39.16 | hippieindamakin8 | *we obtain this new point set to work on to reduce the computational costs |
| 13:39.44 | brlcad | ah okay |
| 13:39.47 | hippieindamakin8 | coresets in this case is an approximate point set the geometric approximations of the point sets |
| 13:40.00 | hippieindamakin8 | of the actual point sets. |
| 13:40.56 | hippieindamakin8 | but the end of it all its an approximate solution. :) |
| 13:42.10 | hippieindamakin8 | brlcad, i ll just put the patch in soon. |
| 13:42.35 | brlcad | no rush, was just wondering if you were still working on it or stuck on some problem or busy, etc :) |
| 13:42.39 | brlcad | hadn't seen you in a while |
