Multivariate Data Analysis via Matrix Decompositions. This course is about using matrix computations to infer useful information from observed data. One may view it as an "applied" version of Stat although it is not necessary to have taken Stat ; the only prerequisite for this course is basic linear algebra. The data analytic tools that we will study will go beyond linear and multiple regression and often fall under the heading of "Multivariate Analysis" in Statistics.
The algorithm improves the asymptotic runtime compared to the prior methods based on pruning e. However, the reference implementation is not optimized for modern hardware features such as the cache hierarchy, vector instruction sets, or multithreading.
We have analyzed the performance of the reference implementation and performed several optimizations .
The resulting code is two to five times faster than the original and provided below. Benchmarks Here are a few example benchmarks.
The complete set can be found in the Master thesis below. The SFFT performance was increased significantly by applying different optimizations and is now about equally efficient as the high- performance FFTW library for large input sizes.
The SFFT implementations are in almost all cases faster than the FFTs; especially version 3 outperforms the other algorithms for all input sizes.
The plot shows speedups of the different optimized SFFT versions compared to their reference implementations. It shows that the most gain was achieved in SFFT v3.
The maximum speedup is above 5. The inventors of the SFFT have generously provided us with a prototype of the code for exact sparse case version 3which is included in the optimized version. The optimized code has the same constraints as the original and is distributed under a GNU public license.Machine Learning Risi Kondor Networks Borja Sotomayor Operating Systems Haryadi Gunawi Note that, except in joint programs, the department will not issue waivers for non-core courses.

For example, if the program reads in "Every good boy deserves fruit", then I would get a table that converts '. However, perhaps the main value of the thesis is its catholic presentation of the field of sequential data modelling.
