Here is yet another exciting data mining application: detecting fake paintings. According to NewScientist, researchers from the Maastricht University (Netherlands) are using data mining techniques to discover whether paintings are original or not. For example, they train a neural network on some Van Gogh’s painting to discover the trends let by its famous author. Even if this technique seems promising, the human intervention cannot be avoided. The human is still involved in the process of the training set establishment. Indeed, a human expert has once to say to the machine which painting really is an authentic one.
