  1. 21. Automatic and unsupervised methods in natural language processing

    Författare :Johnny Bigert; Viggo Kann; joakim Nivre; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Datalogi; Computer science; Datalogi;

    Sammanfattning : Natural language processing (NLP) means the computer-aided processing of language produced by a human. But human language is inherently irregular and the most reliable results are obtained when a human is involved in at least some part of the processing. However, manual workis time-consuming and expensive. LÄS MER

  2. 22. Distributed optimization for the optimal control of electric vehicle fleets

    Författare :Rémi Lacombe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platooning; Optimal control; Electric vehicles; Public transit; Distributed optimization;

    Sammanfattning : Owing to their absence of tailpipe emissions and their independence from fossil fuels, Electric Vehicles (EVs) are currently experiencing a rapid deployment in an attempt to curb global greenhouse gas emissions. EV operation represents a technical challenge, however, as new control algorithms need to be developed to address their limited driving range and their longer charging times. LÄS MER

  3. 23. Complexity and expressiveness for formal structures in Natural Language Processing

    Författare :Petter Ericson; Henrik Björklund; Frank Drewes; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; graph grammars; formal languages; natural language processing; parameterized complexity; abstract meaning representation; tree automata; deterministic tree-walking transducers; mildly context-sensitive languages; hyperedge replacement; tree adjoining languages; minimally adequate teacher;

    Sammanfattning : The formalized and algorithmic study of human language within the field of Natural Language Processing (NLP) has motivated much theoretical work in the related field of formal languages, in particular the subfields of grammar and automata theory. Motivated and informed by NLP, the papers in this thesis explore the connections between expressibility – that is, the ability for a formal system to define complex sets of objects – and algorithmic complexity – that is, the varying amount of effort required to analyse and utilise such systems.

  4. 24. Composition and maintenance of skin resident T-cells in health and disease

    Författare :Elena Hoffer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tissue-resident memory T cells (TRM) reside in healthy skin at sites of previous infections. Upon re-infection, TRM cells rapidly respond by initiating tissue inflammation and exert effector functions to eliminate pathogens. TRM cells are potent effector cells and as such, they are key players in focal inflammatory skin diseases. LÄS MER

  5. 25. Improving Language Models Using Augmentation and Multi-Modality

    Författare :Tobias Norlund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; natural language processing; contextual augmentation; multimodal language modeling; language models;

    Sammanfattning : Language models have become a core component in modern Natural Language Processing (NLP) as they constitute a powerful base that is easily adaptable to many language processing tasks. Part of the strength lies in their ability to embed associations representing general world knowledge. LÄS MER
