Entropy estimation
In various science/engineering applications, such as independent component analysis, image analysis, genetic analysis, speech recognition, manifold learning, and time delay estimation it is useful to estimate the differential entropy of a system or process, given some observations. The simplest and most common approach uses histogram-based estimation, but other approaches have been developed and used, each with its own benefits and drawbacks. The main factor in choosing a method is often a trade-off between the bias and the variance of the estimate, although the nature of the (suspected) distribution of the data may also be a factor, as well as the sample size and the size of the alphabet of the probability distribution.
