2. 1. Understanding Neural Machine Translation : An investigation into linguistic phenomena and attention mechanisms

   Author : Gongbo Tang; Joakim Nivre; Rico Sennrich; Philipp Koehn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neural machine translation; Linguistic phenomena; Ambiguity; Long-range dependency; Morphology; Negation; Attention mechanisms; Interpretation; Computational Linguistics; Datorlingvistik;

   Abstract : In this thesis, I explore neural machine translation (NMT) models via targeted investigation of various linguistic phenomena and thorough exploration of the internal structure of NMT models, in particular the attention mechanism. With respect to linguistic phenomena, I explore the ability of NMT models to translate ambiguous words, to learn long-range dependencies, to learn morphology, and to translate negation—linguistic phenomena that have been challenging for the older paradigm of statistical machine translation.

4. 2. Discourse in Statistical Machine Translation

   Author : Christian Hardmeier; Joakim Nivre; Jörg Tiedemann; Marcello Federico; Lluís Màrquez; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistical machine translation; Discourse-level machine translation; Document decoding; Local search; Pronominal anaphora; Pronoun translation; Neural networks; Computational Linguistics; Datorlingvistik;

   Abstract : This thesis addresses the technical and linguistic aspects of discourse-level processing in phrase-based statistical machine translation (SMT). Connected texts can have complex text-level linguistic dependencies across sentences that must be preserved in translation. However, the models and algorithms of SMT are pervaded by locality assumptions. READ MORE

5. 3. Machine Learning Concepts for Service Data Interoperability

   Author : Jacob Nilsson; Fredrik Sandin; Jerker Delsing; Marcus Liwicki; Tapio Heikkilä; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; system of systems; system of cyber-physical systems; subsymbolic representations; semantic interoperability; dynamic interoperability; Cyber-Physical Systems; Cyberfysiska system;

   Abstract : Industrial automation is transforming by ongoing digitalization efforts to create a flexible industrial internet of things, turning manufacturing facilities into large-scale systems of cyber-physical systems. This development requires addressing the challenging issue of making heterogeneous systems, data models, and standards interoperable, a core problem in designing sustainable service-oriented automation frameworks.

6. 4. Towards conversational speech synthesis : Experiments with data quality, prosody modification, and non-verbal signals

   Author : Bajibabu Bollepalli; Joakim Gustafsson; Jonas Beskow; Matthew Aylett; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Speech synthesis; MPEG compression; Voice Conversion; Artificial Neural Net- works; Laughter synthesis; HTS; Computer Science; Datalogi;

   Abstract : The aim of a text-to-speech synthesis (TTS) system is to generate a human-like speech waveform from a given input text. Current TTS sys- tems have already reached a high degree of intelligibility, and they can be readily used to read aloud a given text. For many applications, e.g. READ MORE

7. 5. From Sequence to Sorting : Prediction of Signal Peptides

   Author : Henrik Nielsen; Philipp Bucher; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

   Abstract : In the present age of genome sequencing, a vast number of predicted genes are initially known only by their putative nucleotide sequence. The newly established field of bioinformatics is concerned with the computational prediction of structural and functional properties of genes and the proteins they encode, based on their nucleotide and amino acid sequences.
