Speed up kernel discriminant analysis

Deng Cai, Xiaofei He, Jiawei Han
2010 The VLDB journal  
In this paper, we present a new algorithm for kernel discriminant analysis, called Spectral Regression Kernel Discriminant Analysis (SRKDA).  ...  LDA can be performed either in the original input space or in the reproducing kernel Hilbert space (RKHS) into which data points are mapped, which leads to kernel discriminant analysis (KDA).  ...  Our analysis essentially follows our previous idea for speeding up LDA [6] .  ...

Incremental Fast Subclass Discriminant Analysis [article]

Kateryna Chumachenko, Jenni Raitoharju, Moncef Gabbouj, Alexandros Iosifidis
2020 arXiv   pre-print
This paper proposes an incremental solution to Fast Subclass Discriminant Analysis (fastSDA). We present an exact and an approximate linear solution, along with an approximate kernelized variant.  ...  The speed-up given by this solution is two-fold: first, the speed-up is achieved as the inverse calculation is omitted; second, the resulting method does not require recalculation of the full kernel matrix  ...  These methods are referred to as fast Subclass Discriminant Analysis (fastSDA) and fast Kernel Subclass Discriminant Analysis (fastKSDA) for the linear and non-linear cases, respectively.  ...

Precise and stable edge orientation signaling by human first-order tactile neurons [article]

Vaishnavi Sukumar, Roland S Johansson, J. Andrew Pruszynski
2022 bioRxiv   pre-print
Represented in the spatial domain, the sequential structure was strikingly invariant across scanning speeds, especially those naturally used in tactile spatial discrimination tasks.  ...  This speed invariance suggests that neurons' responses are structured via sequential stimulation of their subfields.  ...  Regarding the speed effect, for both neuron types, the discrimination accuracy was fairly uniform for speeds up to 45 mm/s, after which it gradually decreased with increasing speed.  ...
