Abstract:

The choice of an input representation for machine learning can have a profound impact on the accuracy of the learned model in classifying novel instances. A reliable method of rapidly estimating the value of a representation, independent of the learner, would be a powerful tool in the search for better representations. We introduce a fast representation- quality measure that is more accurate than Rendell and Ragavan's blurring metric in rank ordering input representations for neural networks on two difficult, real-world datasets. This work constitutes a step forward both in representation quality measures and in our understanding of the characteristics that engender good representations.
