We thank the help from the following group members and users.

Chih-Wei Hsu and Jen-Hao Lee give helpful comments in the early
development.

Carl Staelin from HP labs initiated the development of the python
interface.

2.5.

Ting-Fan Wu helps updating the python interface of libsvm 2.5 and 2.6.

Li-lun Wang helps to test libsvm 2.6.

David James (University of Toronto) helps to initiate the stratified
cross validation code (in libsvm 2.7). Fang-Lan Huang helps the
stratified CV implementation in Java.

S V N Vishwanathan (Australian National University) helps to modify

on handling #SV=0 case in loading model.

Rong-En Fan helps to modify many things from 2.71 to 2.8.

Rong-En Fan helps to write part of the script subset.py for 2.81.

Pei-Chin Wang helps to prepare a code of the precomputed kernel in libsvmtools. The code is improved and merged to libsvm 2.82.

Ed Johnson from San Francisco State University helps to point out a memory leak in svm_binary_svc_probability().

Rong-En Fan helps to write the script `tools/checkdata.py' for checking input
data (available after libsvm 2.85).

Alain Lifchitz from LIP6, France suggests some useful changes from
2.85 to 2.86.
