  1. 1. Combining Machine Learning and Natural Language Processing for Automatic Keyword Extraction

    Författare :Anette Hulth; Lars Asker; Robert Gaizauskas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; automatic keyword indexing; automatic keyword extraction; machine learning; natural language processing; Computer science; Datavetenskap;

    Sammanfattning : Automatic keyword extraction is the task of automatically selecting a small set of terms describing the content of a single document. That a keyword is extracted means that it is present verbatim in the document to which it is assigned. LÄS MER

  3. 2. Diversified Retrieval of Spatial Data with Context

    Författare :Georgios Kalamatianos; Georgios J Fakas; Aristides Gionis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proportionality; Diversity; Keyword Search; Spatial Data; Ranking; Computer Science; Datavetenskap;

    Sammanfattning : The abundance and ubiquity of spatial datasets necessitates their effective and efficient retrieval. For instance, on the web, there are datasets with GIS objects or POIs (e.g. Spatialhadoop datasets), datasets with geo-tagged photographs (e. LÄS MER

  4. 3. Applications of Diversity and the Self-Attention Mechanism in Neural Networks

    Författare :Axel Berg; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; point cloud; self-attention; keyword spotting; deep learning; computer vision; machine learning; label diversity;

    Sammanfattning : This thesis covers three contributions in applications of neural networks. The first is related to diversity and ensemble learning, while the other two cover novel applications of the self-attention mechanism. An important aspect of training a neural network is the choice of objective function. LÄS MER

  5. 4. Performance Testing of Cutting Fluids and Tool Holders in Metal Cutting

    Författare :Varun Nayyar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip Microstructure; Torque; Drilling; Compressed air; Turning; Tool-holding; Force.; Tapping; Keyword: Cutting Fluid;

    Sammanfattning : ABSTRACTThe metal cutting industry has evolved over the last century to the point where an increasing range and complexity of tool holding systems and cutting fluids are available for metal machining in the market. Most of the companies report their cutting fluid cost to be between 7 -17 % of the manufacturing cost. LÄS MER

  7. 5. Development and Evaluation of Web Applications for Investigating Candidate Genes in Rat Models of Complex Diseases

    Författare :Lars Andersson; Göteborgs universitet; []
    Nyckelord :rat; complex disease; rheumatoid arthritis; type 2 diabetes mellitus; QTL; candidate genes; web application; text mining;

    Sammanfattning : Many human diseases, such as rheumatoid arthritis and type 2 diabetes mellitus, have a very complex development, depending on both environmental and multiple genetic factors. By crossing inbred rat strains susceptible to a genetic disorder with strains resistant to the same disorder, genomic regions associated with the disease can be identified, so called quantitative trait loci (QTLs).
