Barnes-Hut-SNE
The paper presents an O(N logN)-implementation of t-SNE — an embedding technique that is commonly used for the visualization of high-dimensional data in scatter plots and that normally runs in O(N). The new implementation uses vantage-point trees to compute sparse pairwise similarities between the input data objects, and it uses a variant of the Barnes-Hut algorithm to approximate the forces be...
متن کاملTheory of Barnes Beta distributions
A new family of probability distributions βM,N , M = 0 · · ·N, N ∈ N on the unit interval (0, 1] is defined by the Mellin transform. The Mellin transform of βM,N is characterized in terms of products of ratios of Barnes multiple gamma functions, shown to satisfy a functional equation, and a Shintani-type infinite product factorization. The distribution log βM,N is infinitely divisible. If M < N...
متن کاملHenry Friesen Award Lecture. Work, the clinician-scientist and human biochemical genetics.
The pursuit of human biochemical genetics has allowed us to understand better how the person with the (genetic) disease differs from the disease the person has and to develop the concept that genetics belongs in all aspects of health care. It is a perspective that comes quite readily to the clinician-scientist, and the restoration of that "species" in the era of functional genomics is strongly ...
متن کاملHalo nevus of the choroid in 150 patients: the 2010 Henry van Dyke Lecture.
OBJECTIVE To evaluate choroidal halo nevus. METHODS We performed a retrospective medical record review on all patients with a clinical diagnosis of choroidal halo nevus treated at the Ocular Oncology Service at Wills Eye Institute from April 1, 1974, through June 30, 2008. Their clinical characteristics and natural history were studied. RESULTS The choroidal halo nevus showed 2 components, ...
متن کاملThe 2006 Henry N . Wagner Lecture : Of Mice and Men ( and Positrons ) — Advances in PET Imaging
There have been major advances in PET technology that cumulatively have helped improve image quality, increased the range of applications for PET, and contributed to the more widespread use of PET. Examples of these technologic advances include whole-body imaging, 3-dimensional imaging, new scintillator materials, iterative reconstruction algorithms, combined PET/ CT, and preclinical PET. New a...
