  1. 1. Preprocessing perceptrons

    Author : Lena Kallin Westin; Patrik Eklund; Lothar Gierl; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Preprocessing perceptron; Production line; Neural networks; Backpropagation; Fuzzy logic; ROC and QROC curves; Multivariate decision limits; Datalogi; Computer science; Datalogi; business data processing; administrativ databehandling;

    Abstract : Reliable results are crucial when working with medical decision support systems. A decision support system should be reliable but also be interpretable, i.e. able to show how it has inferred its conclusions. READ MORE

  2. 2. Morphosyntactic Corpora and Tools for Persian

    Author : Mojgan Seraji; Joakim Nivre; Carina Jahani; Jan Hajic; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Persian; language technology; corpus; treebank; preprocessing; segmentation; part-of-speech tagging; dependency parsing; Computational Linguistics; Datorlingvistik;

    Abstract : This thesis presents open source resources in the form of annotated corpora and modules for automatic morphosyntactic processing and analysis of Persian texts. More specifically, the resources consist of an improved part-of-speech tagged corpus and a dependency treebank, as well as tools for text normalization, sentence segmentation, tokenization, part-of-speech tagging, and dependency parsing for Persian.

  3. 3. Adaptive Baseband Pro cessing and Configurable Hardware for Wireless Communication

    Author : Rakesh Gangarajaiah; Integrerade elektroniksystem; []
    Keywords : Wireless receivers; baseband processing; LTE-A; MIMO; OFDM; carrier aggregation; channel preprocessing; adaptive signal processing; non-linearity mitigation; massive MIMO;

    Abstract : The world of information is literally at one’s fingertips, allowing access to previously unimaginable amounts of data, thanks to advances in wireless communication. The growing demand for high speed data has necessitated theuse of wider bandwidths, and wireless technologies such as Multiple-InputMultiple-Output (MIMO) have been adopted to increase spectral efficiency.

  4. 4. Resource Optimized Stereo Matching in Reconfigurable Hardware for Autonomous Systems

    Author : Fredrik Ekstrand; Lars Asplund; Rafael Garcia; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

    Abstract : There is a need for compact, high-speed, and low-power vision systems for enabling real-time mobile autonomous applications. The best approach to achieve this is to implement the bulk of the application in hardware. READ MORE

  5. 5. On performance analysis of subspace methods in system identification and sensor array processing

    Author : Magnus Jansson; Bo Wahlberg; Mats Molander; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subspace methods; system identification; state-space models; linear regression; sensor array processing; performance analysis; EM algorithm; minimum redundancy array;

    Abstract : This thesis addresses the issue of performance analysis of subspace-based parameter estimation methods in two different applications, namely system identification and sensor array processing.  The objective is to study the quality of the estimated models as the amount of data increases, and to suggest improvements and give user guidelines.
