  1. 21. Investigating the Correlation Between Marketing Emails and Receivers Using Unsupervised Machine Learning on Limited Data : A comprehensive study using state of the art methods for text clustering and natural language processing

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Christoffer Pettersson; [2016]
    Keywords : Machine learning; Unsupervised; Natural language processing; nlp; clustering; centroid based; k-means; text clustering; limited data; email clustering; lsa; svd; tf-idf; dimensionality reduction; the gap statistic; Lloyd s algorithm; vectorization; feature extraction;

    Abstract : The goal of this project is to investigate any correlation between marketing emails and their receivers using machine learning and only a limited amount of initial data. The data consists of roughly 1200 emails and 98.000 receivers of these. Initially, the emails are grouped together based on their content using text clustering. READ MORE

  3. 22. Efficient Implementation of 3D Finite Difference Schemes on Recent Processor Architectures

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Frederick Ceder; [2015]
    Keywords : hpc; high performance computing; intel; haswell; xeon phi; knights corner; burgers equation; finite difference methods; fdm; ftcs; parallel programming; vectorization; simd;

    Abstract : Efficient Implementation of 3D Finite Difference Schemes on Recent Processors Abstract In this paper a solver is introduced that solves a problem set modelled by the Burgers equation using the finite difference method: forward in time and central in space. The solver is parallelized and optimized for Intel Xeon Phi 7120P as well as Intel Xeon E5-2699v3 processors to investigate differences in terms of performance between the two architectures.

  4. 23. Parallel implementation of the projected Gauss-Seidel method on the Intel Xeon Phi processor – Application to granular matter simulation.

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Emil Rönnbäck; [2014]
    Keywords : ;

    Abstract : Being able to simulate granular matter is important, because they are ubiquitous both in nature and in industry. Some examples of granular materials are ore, sand, coffee, rice, corn, and snow. Research and development of new, more accurate, and faster methods to simulate even more complex materials with millions of particles are needed. READ MORE

  5. 24. Data-parallel Acceleration of PARSEC Black-Scholes Benchmark

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : August Andrén; Patrik Hagernäs; [2013]
    Keywords : ;

    Abstract : The way programmers has been relying on processor improvements to gain speedup in their applications is no longer applicable in the same fashion. Programmers usually have to parallelize their code to utilize the CPU cores in the system to gain a signicant speedup. READ MORE

  6. 25. HaGPipe : Programming the graphics pipeline in Haskell

    University essay from Akademin för innovation, design och teknik

    Author : Tobias Bexelius; [2009]
    Keywords : Haskell; GPU; graphics; functional programming; shaders;

    Abstract :   In this paper I present the domain specific language HaGPipe for graphics programming in Haskell. HaGPipe has a clean, purely functional and strongly typed interface and targets the whole graphics pipeline including the programmable shaders of the GPU. It can be extended for use with various backends and this paper provides two different ones. READ MORE
