Finding Structure in Data: The central goal of unsupervised learning is to discover the underlying structure and patterns in the data. Since the type of structure varies with the data, we instead define a "goal" to extract those patterns which are useful in accomplishing it by constructing a global objective function. In doing so, we internally derive a teaching signal from the data itself through the principle of self organization. With the "goal" embedded in the cost function, these local forces define the rules of interaction between the data particles. Self organization of these particles should then reveal the structure in the data relevant to this goal. In this talk, I will be show how information theoretic learning principles can be used to derive these self organizing rules. A new information theoretic framework for unsupervised learning will be presented. In particular, the mean shift algorithms appear as special cases under this general framework giving them a whole new perspective. We will see how this framework could be applied to wide variety of applications ranging from clustering, principal curves to vector quantization. | |
