Visualizing Data using t-SNE - Laurens van der Maaten
lvdmaaten.github.ioFor high-dimensional data that lies on or near a low-dimensional, non-linear manifold it is usu-ally more important to keep the low-dimensional representations of very similar datapoints close together, which is typically not possible with a linear mapping. A large number of nonlinear dimensionality reduction techniques that aim to preserve the ...

Dimensional Modelling by Example - Database Answers
databaseanswers.orgHere we discuss the use of Subject Areas as a techniques for designing Dimensional Models. We take the simple example of Customers, Products and Revenue. This analysis shows that the three dominant Subject Areas are :- 1. Customers 2. Products 3. Revenue from Sales of Products to Customers. Revenue
-dimensional Fourier Transform
see.stanford.edudimensional case and higher dimensions, we want to mimic the one-dimensional setting and arguments as much as possible. It is a measure of the naturalness of the fundamental concepts that the extension to higher dimensions of the basic ideas and the mathematical definitions that we’ve used so far proceeds almost automatically.
Chapter 5 Dimensional Analysis and Similarity
www.pmt.usp.brDimensional analysis can also be useful in theories, as a compact way to present an analytical solution or output from a computer model. Here we concentrate on the pre-sentation of experimental fluid-mechanics data. Basically, dimensional analysis is a method for reducing the number and complexity
Chapter 3. Special Techniques for Calculating Potentials
teacher.pas.rochester.eduChapter 3. Special Techniques for Calculating Potentials Given a stationary charge distribution r()r we can, in principle, calculate the electric field: E ()r = 1 4pe 0 Dr ˆ Ú ()Dr 2 r()r ' dt' where Dr = r '-r . This integral involves a vector as an integrand and is, in general, difficult to calculate.
