  1. 1. Principal Word Vectors

    Author : Ali Basirat; Joakim Nivre; Hinrich Schütze; Uppsala universitet; []
    Keywords : HUMANITIES; HUMANIORA; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; HUMANIORA; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; HUMANITIES; word; context; word embedding; principal component analysis; PCA; sparse matrix; singular value decomposition; SVD; entropy;

    Abstract : Word embedding is a technique for associating the words of a language with real-valued vectors, enabling us to use algebraic methods to reason about their semantic and grammatical properties. This thesis introduces a word embedding method called principal word embedding, which makes use of principal component analysis (PCA) to train a set of word embeddings for words of a language.

  2. 2. Digital Hardware Aspects of Multiantenna Algorithms

    Author : Fredrik Edman; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; MIMO; FPGA; Implementation; Hardware; Matrix; Inversion; QR-decomposition; SVD; Capon; Signal processing; Signalbehandling; Electronics; Elektronik och elektroteknik; Elektronik; Telecommunication engineering; Telekommunikationsteknik; Electronics and Electrical technology;

    Abstract : The field of wireless communication is growing rapidly, with new requirements for the next generation of mobile and wireless communications technology. In order to achieve the capacities needed for future wireless systems, the design and implementation of advanced communications techniques such as multiantenna systems is required. READ MORE

  3. 3. Multi-LSTM Acceleration and CNN Fault Tolerance

    Author : Stefano Ribes; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Machine Learning; Fault Tolerance; LSTMs; Caffe; CNNs; SVD; Roofline Model; Compression; HLS; FPGA;

    Abstract : This thesis addresses the following two problems related to the field of Machine Learning: the acceleration of multiple Long Short Term Memory (LSTM) models on FPGAs and the fault tolerance of compressed Convolutional Neural Networks (CNN). LSTMs represent an effective solution to capture long-term dependencies in sequential data, like sentences in Natural Language Processing applications, video frames in Scene Labeling tasks or temporal series in Time Series Forecasting.

  4. 4. Crocodiles, Masks and Madonnas : Catholic Mission Museums in German-Speaking Europe

    Author : Rebecca Loder-Neuhold; Magnus Lundberg; Kajsa Ahlstrand; Hermann Mückler; Uppsala universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Mission museums; mission collections; mission exhibitions; mission history; Catholic mission; mission congregations; missionary networks; history of anthropology; anthropological objects; exhibits; history of collecting; Missionary Sisters of St. Peter Claver SSPC ; Society of the Divine Word SVD ; Sacred Heart Missionaries MSC ; Missionsmuseen; Missionssammlungen; Missionsausstellungen; Missionsgeschichte; Katholische Mission; Missionskongregationen; missionarische Netzwerke; Anthropologiegeschichte; anthropologische Objekte; Ausstellungsstücke; Geschichte des Sammelns; Missionsschwestern vom heiligen Petrus Claver SSPC ; Gesellschaft des göttlichen Wortes SVD ; Herz-Jesu-Missionare MSC ; Historia; History;

    Abstract : This dissertation examines mission museums established by Catholic mission congregations in Germany, Austria, and Switzerland from the 1890s onwards. The aim is to provide the first extensive study on these museums in a way that contributes to current blind spots in mission history, and the history of anthropology and museology. READ MORE

  5. 5. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies

    Author : Afshin Samadi; Lennart Söder; Olof Samuelsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. READ MORE
