This code demonstrates the convex learning formulation from partial label presented in the above paper. It can use the Annotated Faces on TV dataset or your own data. Please cite the dataset if you use it in your work:

Super simple matlab script to download/unpack/compile&run code and data
The matlab script below (it contains unix/mac specific code at the
beginning) will download code and data under the directory:
Simply paste the following into matlab command prompt. That's it !
Alternatively (for example on windows), you can do this manually by downloading the code here: partial_label_learning_toolbox.tar.gz.
fun_curl_and_unzip=@(url,dir_base)(dos(['cd ',dir_base,'; curl ',url,' | tar -zx']));
%% download data
%% rename path
%% do the following only once to compile mex files, including liblinear:
%% run the demos
% run demo for ambiguous faces in the wild with random ambiguity sets
% run demo for ambiguous faces in TV with random ambiguity sets
% run demo for ambiguous faces in TV with ambiguity sets computed from screenplay
