The Jubatus library is a online machine learning framework which runs in distributed environment.

See http://jubat.us for details.

Jubatus publicly supports Ubuntu >= 12.04 , Redhat Linux >= 6.2 . In other platforms, some may work if they have gcc >= 4.4 .

For minimal standalone mode, Jubatus requires libevent >= 1.4 , pficommon >= 1.3.1 , google-glog , libmsgpack, python >= 2.6 . Please install these softwares with headers before installation.

$ git clone git://github.com/jubatus/jubatus.git
$ cd jubatus
$ ./waf configure --disable-re2
$ ./waf build
$ sudo ./waf install
$ jubaclassifier

Here Jubatus classifier server have started. Enjoy!

LGPL 2.1

Improvements

• RPC enhances to many exceptions and provide new error handling interface (#49)

Bugfix

• #73, #69, #66, #65

Improvements

• #47, #50, #34, #36, #37, #31, #19, and other small bugfix

Improvements

• Simpler interfaces at classifier, regression and recommender
  • Clients are NOT COMPATIBLE with previous releases
• Now mix works concurrently in multiple threads (except tf-idf counting)
• Asynchronous RPC to multiple servers at once
• Add --version option
• Interface description language changed from C++-like to Annotated MessagePack-IDL
• Minor error handling
• A bit more tested than previous releases

Bugfix

• #30, #29, #22

Bugfix release: #28

New Features

• recommender
  • support fast similar item search, real-time update, distributed data management
  • inverted index : exact result, fast search
  • locality sensitive hash : approximate result, fast search, small working space
• regression
  • online SVR using passive agressive algorithm
  • as fast as current classifier
• stat
  • a Key(string)-Value(queue<double>)
  • O(1) cost of getting sum, standard deviation, max, min, statistic moments for each queue
• server framework
  • less-tightly coupled distributed processing framework with each ML implementation
  • idl & code generator - make it easy to write own jubatus system
  • removed public release of client libraries (so easy to generate!)
  • multiple mix - mutiple data objects can be mixed in one jubatus system

Bugfix

• duplicate key entry in fv_converter breaks the parameter

Bugfix release

Hello Jubatus!

First release: including classifier, and mix operation
