| wiking | blackburn: ping? | 17:27 |
| blackburn | wiking: pong | 17:33 |
| wiking | do we have a lasso solver? | 17:34 |
| blackburn | wiking: yes | 17:37 |
| blackburn | regression? binary? multiclass? | 17:37 |
| wiking | multiclass | 17:38 |
| blackburn | wiking: tree guided would work | 17:40 |
| blackburn | MulticlassTreeGuidedLogisticRegression | 17:40 |
| blackburn | wiking: it is not trivial to use though :D | 18:44 |
| blackburn | kinda rocket science and requires a phd | 18:44 |
| blackburn | I mean it is not documented IIRC :D | 18:44 |
| wiking | yeah i can see that | 19:15 |
| blackburn | wiking: it is actually for tree lasso but it works as basic lasso as well | 19:16 |
| blackburn | wiking: hmm actually MulticlassLogisticRegression is L1 reg logistic regression | 19:17 |
| blackburn | is that what you need? | 19:17 |
| wiking | hehehe | 19:17 |
| wiking | i need to optimize | 19:17 |
| wiking | \lambda \sum ||\beta_i||_2 | 19:18 |
| wiking | - f(\lambda) | 19:18 |
| wiking | blackburn: ? | 19:48 |
| blackburn | wiking: what is beta what is f? | 19:48 |
| wiking | \beta is an M lenght vector | 19:49 |
| wiking | while L is a loss function | 19:49 |
| blackburn | well bfgs, etc :) | 19:51 |
| wiking | lol | 19:57 |
| wiking | ookeey face | 19:59 |
| wiking | there's this paper | 20:02 |
| wiking | Heterogeneous Feature Machines for Visual Recognition | 20:02 |
| wiking | has a different approch for mkl | 20:02 |
