Bump Hunting with Non-gaussian Kernels
It is well known that the number of modes of a kernel density estimator is monotone nonincreasing in the bandwidth if the kernel is a Gaussian density. There is numerical evidence of nonmonotonicity in the case of some non-Gaussian kernels, but little additional information is available. The present paper provides theoretical and numerical descriptions of the extent to which the number of modes...
متن کاملBump hunting in high-dimensional data
Many data analytic questions can be formulated as (noisy) optimization problems. They explicitly or implicitly involve ®nding simultaneous combinations of values for a set of (``input'') variables that imply unusually large (or small) values of another designated (``output'') variable. Speci®cally, one seeks a set of subregions of the input variable space within which the value of the output va...
متن کاملTowards Resolution of the Enigmas of P -Wave Meson Spectroscopy
The mass spectrum of P -wave mesons is considered in a nonrelativistic constituent quark model. The results show the common mass degeneracy of the isovector and isodoublet states of the scalar and tensor meson nonets, and do not exclude the possibility of a similar degeneracy of the same states of the axial-vector and pseudovector nonets. Current experimental hadronic and τ decay data suggest, ...
متن کاملRejoinder: Discussion of Bump Hunting in High Dimensional Data
We thank all of the discussants for taking the time to contribute, and for both their compliments and helpful criticism. Before responding in detail, we address two general concerns that ran throughout many of the discussions. 1 Computation Several discussants raised the issue of the computational requirements of the peeling algorithm (Section 7). They were concerned about its ability to scale ...
متن کاملSubgroup Discovery Using Bump Hunting on Multi-relational Histograms
We propose an approach to subgroup discovery in relational databases containing numerical attributes. The approach is based on detecting bumps in histograms constructed from substitution sets resulting from matching a first-order query against the input relational database. The approach is evaluated on seven data sets, discovering interpretable subgroups. The subgroups’ rate of survival from th...
