  1. 1. Using Semi-Supervised Learning for Email Classification

    University essay from KTH/Matematik (Avd.)

    Author : Anders Inde; [2022]
    Keywords : applied mathematics; semi-supervised learning; self-training; doc2vec; classification; tillämpad matematik; semi-vägledd inlärning; self-training; doc2vec; klassificering;

    Abstract : In this thesis, we investigate the use of self-training, a semi-supervised learning method, to improve binary classification of text documents. This means making use of unlabeled samples, since labeled samples can be expensive to generate. More specifically, we want to classify emails that are retrieved by Skandinaviska Enskilda Banken (SEB). READ MORE

  3. 2. Evaluating an Automated Method for Digitizing Detailed Plans : Using a Swedish Municipality as Test Case

    University essay from KTH/Geoinformatik

    Author : Linnea Bergmark; [2022]
    Keywords : GIS; digitization; maps; georeferencing; vectorization; detailed plans; automated digitization; GIS; digitalisering; kartor; georeferering; vektorisering; detaljplaner; automatiserad digitalisering;

    Abstract : Frågan om digitala detaljplaner är mer relevant än någonsin i Sverige efter nya direktiv från svenska myndigheter som ålägger kommunerna att digitalisera delar av sina planarkiv. Att digitalisera redan existerande detaljplaner är en tidskrävande process, vilket innebär att effektiva automatiserade metoder kan bli värdefulla för att kunna spara tid. READ MORE

  4. 3. Vectorization of the Jacobi method with single- and multiple right-hand sides

    University essay from Lunds universitet/Matematikcentrum; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Patrik Paaso; [2022]
    Keywords : C ; Vectorization; SIMD; DUNE; VCL; Vc; Jacobi method; Jacobi iteration; discrete Poisson s equation; Stationary iterative methods; Computational science; Optimization; Numerical analysis; Mathematics and Statistics;

    Abstract : Vectorization has been an important consideration for scientific com- puting performance for a long time. Early super computers were designed around vectorization, the so called ”vector computers”, but recent trends point toward favouring other computer architectures, and vector comput- ers are much more rare than they used to be.

  5. 4. Spatiotemporal change of stream and wetland features over 140 years in an agricultural catchment in southern Sweden : an assessment of historical maps in GIS

    University essay from SLU/Dept. of Soil and Environment

    Author : Linnea Lindelöf; [2021]
    Keywords : historical map; wetland; stream; GIS; sinuosity index; land cover change; georeferencing; vectorizing;

    Abstract : The Swedish agricultural landscape has historically changed by draining wetlands and hydromorphological impacts by straightening and redirect watercourses. Drainage has been a part of Sweden’s agricultural history, dating back to the 13th century with its peak in the 19th and 20th centuries. READ MORE

  6. 5. Idiom-driven innermost loop vectorization in the presence of cross-iteration data dependencies in the HotSpot C2 compiler

    University essay from Linköpings universitet/Programvara och system

    Author : William Sjöblom; [2020]
    Keywords : compiler; vectorization; SIMD; Java; HotSpot; code optimization; reductions; prefix sums; parallel programming; data-level parallelism;

    Abstract : This thesis presents a technique for automatic vectorization of innermost single statement loops with a cross-iteration data dependence by analyzing data-flow to recognize frequently recurring program idioms. Recognition is carried out by matching the circular SSA data-flow found around the loop body’s φ-function against several primitive patterns, forming a tree representation of the relevant data-flow that is then pruned down to a single parameterized node, providing a high-level specification of the data-flow idiom at hand used to guide algorithmic replacement applied to the intermediate representation.
