| ptizoom | Hi, I have a few Q... is there a "task" force for swigging shogun and perl-module? | 09:52 |
| -!- blackburn [5bdfb203@gateway/web/freenode/ip.91.223.178.3] has quit [Ping timeout: 245 seconds] | 09:53 | |
| ptizoom | also is there a modularity with shogun (like in pybrain)? | 09:54 |
| ptizoom | I am looking also for IO interface with relationnal DB ? | 09:56 |
| wiking | ptizoom: which db would u like to use? | 09:57 |
| wiking | ptizoom: as far as i understand from you question there's a similar modularity with shogun like in pybrain (see modular_python interface of shogun)... but if you meant something else then please specify | 09:58 |
| ptizoom | DB: hi, I am using db through SQL ! nothing fancy! | 09:59 |
| wiking | ptizoom: yeah but which particular db? | 09:59 |
| ptizoom | DB: I am using Class::DBI from perl, and relations has_many, ... to any of SQLite3, Postgres, MySQL. | 10:02 |
| wiking | ah yeah | 10:03 |
| wiking | well afaik it's possible to make a new IO class | 10:03 |
| wiking | only thing is that we'd need to choose a good library that does all the wrapping for the most common DBs | 10:03 |
| wiking | but then again u can do that by your own... i mean to write the whole datafetching in python put the output into a numpy array and use that in shogun | 10:04 |

| ptizoom | db:one shall think of accessing data with a gradiant of efficiency: mmap,io-sockets-ibus-handlers to many block devices, cluserised-netted-devices | 10:17 |
| wiking | ? | 10:19 |
| ptizoom | no worries! | 10:19 |
| wiking | it's up to you how you gather your data | 10:19 |
| wiking | the only time i think you'll need the special IO class for DB | 10:20 |
| ptizoom | ok, it is a good deal! | 10:20 |
| wiking | if u want to use streamingfeatures | 10:20 |
| ptizoom | ah... IO classes for DB! | 10:20 |
| ptizoom | and why so? | 10:20 |
| ptizoom | IO classes for db are a nightmare..... | 10:21 |
| wiking | i'm just saying that for straeamingfeatures you'd need your own implementation of how to fetch data from the DB one-by-one | 10:23 |
| sonne|work | ptizoom: no one attempted that for perl - but given swig is working stably it should not be too hard ... basically writing typemaps for perl arrays etc | 10:23 |
| wiking | but it's not rocketscience at all to write an sql query for that ... | 10:23 |
| ptizoom | well wiking, there is more than sql queries.... db can be quite sofisticated, one need to manage db access, tables, and raw, then those are relationel... etc... | 10:26 |
| wiking | ptizoom: ? we're just talking about accessing features from db | 10:27 |
| ptizoom | the perl-dbx/dbi classes are quite extricated and have been evolving since the begining of it! | 10:27 |
| ptizoom | db are the most sophisticated ways of storing data (and indeed accessing features)... I think these are important to grow machine learning | 10:30 |
| ptizoom | I just wanted to check with you where you put the bundaries of IO? | 10:32 |
| ptizoom | my problem is, parsing one data format to a "shogun" format... really. | 10:34 |
| ptizoom | ok, for perl, I would like to give a go to swig it...see you in a few month! | 10:42 |
