| LarstiQ | matti: no, it is what I do for a living | 00:01 |
|---|---|---|
| matti | Oh. | 00:02 |
| matti | Hehe. | 00:02 |
| matti | So you are an expert then. | 00:02 |
| *** ambv has quit IRC | 00:06 | |
| LarstiQ | uh oh ;) | 00:10 |
| matti | ;] | 00:12 |
| matti | Right. | 00:12 |
| matti | I am building simple Naive Bayes Classifier. A bit of Levenshtein distance here and there. | 00:13 |
| matti | I am looking at using B-spaces (Banach Spaces) at the moment, | 00:13 |
| matti | Hmm... | 00:13 |
| matti | Exciting this is. | 00:13 |
| matti | This data mining. | 00:13 |
| * LarstiQ nods | 00:14 | |
| matti | Oh come on. | 00:15 |
| matti | Its fun! | 00:15 |
| LarstiQ | it is! | 00:15 |
| matti | Tell me. What do you do usually? | 00:17 |
| LarstiQ | matti: algorithm wise? | 00:18 |
| matti | Yep | 00:18 |
| LarstiQ | matti: SVM | 00:18 |
| matti | Support Vector Machine? | 00:20 |
| LarstiQ | yeah | 00:20 |
| matti | How does it work? | 00:20 |
| matti | Ah. | 00:20 |
| matti | A n-dimensional space. | 00:20 |
| matti | I see. | 00:21 |
| LarstiQ | matti: spanning a maximum margin hyperplane | 00:21 |
| LarstiQ | matti: the real fun is in the kernel | 00:21 |
| LarstiQ | matti: whereby you don't have to know how to explicitly map to the higher dimensional space, just know how to calculate dot products | 00:21 |
| matti | Give me a real life example. | 00:22 |
| matti | How can one use this. | 00:22 |
| LarstiQ | matti: a classification problem would be cancer/no cancer on breast scans | 00:23 |
| matti | Yep. | 00:23 |
| LarstiQ | matti: a regression problem: predict the maximum daily electricla load of a network | 00:24 |
| *** ambv has joined #europython | 00:24 | |
| LarstiQ | matti: that one was a EUNITE contest | 00:24 |
| matti | ;] | 00:24 |
| matti | LarstiQ: I am looking at PyML | 00:24 |
| LarstiQ | right | 00:25 |
| * LarstiQ hasn't really used any of the python libraries | 00:25 | |
| matti | ;] | 00:27 |
| matti | Nice. | 00:28 |
| matti | I might bit a bit too old for that already. | 00:28 |
| matti | ;/ | 00:28 |
| LarstiQ | matti: we have our own svmlight bindings though ;) | 00:29 |
| matti | ;] | 00:32 |
| matti | I wish I could live forever. | 00:35 |
| matti | There is so much to learn. | 00:35 |
| * LarstiQ goes to bed | 00:36 | |
| matti | Sleep tight LarstiQ | 00:37 |
