“…Hughes noted, "If insufficient sample data are available to estimate the pattern probabilities accurately, then a Bayes recognizer is not necessarily optimal". 53,57 Various researchers correctly criticized Hughes' work by pointing out that the paradoxial peaking phenomenon observed therein was not real and was due to the estimate of unknown cell probabilities from the data. [57][58][59][60] In other words, the peaking phenomenon observed by Hughes was essentially within a frequentist framework, not a Bayesian.…”

“…This relatively small value highlights the conservative character of Hughes' distribution-free approach; for example, in practice, where one deals with a fixed distribution of the data, the optimal number of features would typically be larger than the ones observed in Fig. ( 8 ), so that sample size recommendations based on this analysis tend to be pessimistic --- a fact that was pointed out in [ 37 ]. Nevertheless, the qualitative behavior of the analysis is entirely correct.…”

“…Another major challenge for HS image processing is the large amount of data. An imager can capture tens or hundreds of frames, which can lead to the Hughes phenomenon, whereby the accuracy gradually increases as the number of dimensions increases, but decreases after a certain number of dimensions is reached [ 16 ], as well as producing redundancy among the samples [ 17 ]. These challenges can be avoided computationally, for instance, by employing common feature extraction methods.…”
