Toolbox
Product: Fedora
Version: rawhide

Description:
The SHOGUN machine learning toolbox's focus is on large scale kernel
methods and especially on Support Vector Machines (SVM). It provides
a generic SVM object interfacing to several different SVM implementations,
among them the state of the art LibSVM. Each of the SVMs can be combined
with a variety of kernels. The toolbox not only provides efficient
implementations of the most common kernels, like the Linear, Polynomial,
Gaussian and Sigmoid Kernel but also comes with a number of recent string
kernels as e.g. the Locality Improved, Fischer, TOP, Spectrum, Weighted
Degree Kernel (with shifts). For the latter the efficient LINADD
optimizations are implemented. Also SHOGUN offers the freedom of working
with custom pre-computed kernels. One of its key features is the "combined
kernel" which can be constructed by a weighted linear combination of a
number of sub-kernels, each of which not necessarily working on the same
domain. An optimal sub-kernel weighting can be learned using Multiple
Kernel Learning. Currently SVM 2-class classification and regression
problems can be dealt with. However SHOGUN also implements a number of
linear methods like Linear Discriminant Analysis (LDA), Linear Programming
Machine (LPM), (Kernel) Perceptrons and features algorithms to train hidden
Markov-models. The input feature-objects can be dense, sparse or strings
and of type int/short/double/char and can be converted into different
feature types. Chains of "pre-processors" (e.g. subtracting the mean) can
be attached to each feature object allowing for on-the-fly pre-processing.
SHOGUN is implemented in C++ and offers interfaces for
* CLI
* Lua
* Mono (C#)
* Octave
* Python
* Ruby
Koji Builds:
el5: no build ---> missing dependencies
el6: no build ---> missing dependencies
F18: no build ---> will be soon EOL
F19: no build ---> only scratch-build for rawhide, because srpm is huge
F20: no build ---> only scratch-build for rawhide, because srpm is huge
Frh: currently uploading, will post url during today
Issues:
fedora-review shows no obvious issues. AFAIK there might be some false
positives from rpmlint.

SRPM URL:
http://besser82.fedorapeople.org/review/shogun-3.0.0-0.1.fc20.src.rpm
Additional Information:
SRPM is ~250 MBytes. Build takes ~15 mins on i7-2860QM (4-core with HT =
8 Threads). BuildRequires are ~1 GByte. Parallel-make will use ~1.5
GBytes of RAM per thread. BuildDir needs ~15 Gbytes of disk-space.
Thanks for review in advance!
