2.5 Nonparametric Methods - Pattern Recognition and Machine Learning

In this video, we start our discussion of nonparametric methods for estimating an unknown probability distribution from samples. We discuss the method of histograms, in which we model the distribution as bins of constant probability. This method is useful in 1 or 2 dimensions for visualizing the data, but is ineffective in high dimensions because the number of data points required to meaningfully occupy the bins becomes enormous, an example of the curse of dimensionality.
