The reflectance spectrum of the species in a hyperspectral data can be modelled as an n­dimensional vector. The spectral angle mapper computes the angle between the vectors which is used to discriminate the species. The spectral information divergence models the data as a probability distribution so that the spectral variability between the bands can be extracted using the stochastic measures. ...

Topological data analysis is a noble approach to extract meaningful information from high-dimensional data and is robust to noise. It is based on topology, which aims to study the geometric shape of data. In order to apply topological data analysis, an algorithm called mapper is adopted. The output from mapper is a simplicial complex that represents a set of connected clusters of data points. I...

Motivation: Optimizing seed selection is an important problem in read mapping. The number of non-overlapping seeds a mapper selects determines the sensitivity of the mapper while the total frequency of all selected seeds determines the speed of the mapper. Modern seed-and-extend mappers usually select seeds with either an equal and fixed-length scheme or with an inflexible placement scheme, bot...

Cloud computing refers to applications delivered as services over the Internet. Cloud systems employ policies that are inherently dynamic in nature and that depend on temporal conditions defined in terms of external events, such as the measurement of bandwidth, use of hosts, intrusion detection or specific time events. In this paper, we investigate an optimized resource management scheme named ...

Reeb spaces, as well their discretized versions called Mappers, are common descriptors used in topological data analysis, with plenty of applications various fields science, such computational biology and visualization, among others. The stability quantification the rate convergence Mapper to space has been studied a lot recent works (Brown et al. CoRR. arXiv:1909.03488 , 2019; Carrière Oudot F...

Quantifiability is a concept in MapReduce Analytics based on the following two conditions: (a) a mapper should be cautious, that is, should not exclude any reducer's shuffle and sort strategy from consideration; and (b) a mapper should respect the reducers' shuffle and sort preferences, that is, should deem a reducer's shuffle and sort strategy ki infinitely more likely than k&ap...

We present a new nonconventional approach for designing and organizing register rename mappers that can be applied in modern out-of-order processor chips. A content-addressable memory (CAM) configuration optimal for such a register mapper application was developed. The structure of the CAM and search engine, described in this paper, facilitates the implementation of the register mapper as a gro...
