CLOP is a software package containing several ready-to-use machine learning algorithms which is developed during Performance Prediction Challenge, as a part of Model Selection Workshop in IEEE World Congress on Computational Intelligence, Vancouver, BC, Canada, July 2006. For more information and for related citations, please refer to the following paper:

Isabelle Guyon, Amir Saffari, Gideon Dror, and Joachim Buhmann, Performance Prediction Challenge, In Proceedings of International Conference on Neural Networks (IJCNN), IEEE World Congress on Computational Intelligence (WCCI) 2006, Pages: 2958-2965, Vancouver, British Columbia, Canada, July 2006.

CLOP is based on SPIDER package from Department of Empirical Inference for Machine Learning and Perception, Max Planck Institute for Biological Cybernetics, Tuebingen, Germany. CLOP has more algorithms provided by challenge organizers compared to Spider and it runs on MATLAB, but it does not depend on any particular toolbox of MATLAB.

  1. Hi,

    I tried to use your package however I wonder what is the data file format. I could not find in any documents that how the files and file formats should be. I am actually try to use your package for feature selection. I almost check all feature dataset fie format but non of them works. I got the following error and so far I couldn\’t find what is the reason.

    ??? Error using ==> fscanf
    Invalid file identifier. Use fopen to generate a valid file identifier.

    Error in ==> read_parameters at 12
    p.data_type=fscanf(fp, \’Data type: %s\\n\’);

    Error in ==> create_data_struct at 19
    p = read_parameters(filename);

    1. Hi Diego,

      As far as I know, it’s been designed for binary, but you can easily write a 1-vs-all multi-class classifier for it.

      Cheers, Amir

  2. Hi,
    I wanted to know if CLOP is machine dependent? For instance if I am using a 64-bit processor and someone else is using a 32-bit one, is the same CLOP program supposed to give different results on both the machines?
