  How can I use particle swarm optimization for classification?

  I need to classify raw data and hope I could use particle swarm optimization method to classify part of the data. I hope to predict the remaing data.

  Can anybody help me on Computational Creativity?

  I am a PG student and taken computational creativity as a study topic. My guide has asked me to pursue a problem in this field. I am not able to find a problem which can be tackled at my level, asI am a PG student and taken computational creativity as a study topic. My guide has asked me to pursue a problem in this field. I am not able to find a problem which can be tackled at my level, as this is a new field and most of the research work belongs to domain of art, music, maths, etc. I am looking for a problem which is not very fundamental. The problem should help me to explore application side of computational creativity.

  I want to look for a method for detecting faces from images, which are most effective currently. Thank for your good proposal. I have been using the method of opencv to train a classifier recently. However, no good results are obtained. Most importantly, I set numbers of stage to 20. But the train terminates before 20. I use 19998 positive Samples and 32000 negative samples. I want to listen your option.

    Hi farid, for a good comparison in EAs you have to compare 2 significants: 1) time elapsed for each algorithm 2) the correct rate of each algorithm for the defined function
