1. 1. Online Dimensionality Reduction

   Författare :Kaito Ariu; Alexandre Proutiere; Mikael Johansson; Richard Combes; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In this thesis, we investigate online dimensionality reduction methods, wherethe algorithms learn by sequentially acquiring data. We focus on two specificalgorithm design problems in (i) recommender systems and (ii) heterogeneousclustering from binary user feedback. LÄS MER

3. 2. Learning from Interactions : Forward and Inverse Decision-Making for Autonomous Dynamical Systems

   Författare :Inês de Miranda de Matos Lourenço; Bo Wahlberg; Sandra Hirche; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intelligent systems; autonomous decision-making; Reinforcement Learning; Markov models; Human-Robot Interaction; Biologically-inspired systems; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Decision-making is the mechanism of using available information to generate solutions to given problems by forming preferences, beliefs, and selecting courses of action amongst several alternatives. In this thesis, we study the mechanisms that generate behavior (the forward problem) and how their characteristics can explain observed behavior (the inverse problem). LÄS MER

4. 3. Holistic Grasping: Affordances, Grasp Semantics, Task Constraints

   Författare :Martin Hjelm; Danica Kragic; Markus Vincze; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; robotics; robotic grasping; grasping; cognition; embodied cognition; computer vision; machine learning; artificial intelligence; AI; Gaussian process; Gaussian process latent variable model; GPLVM; 3D vision; point cloud features; robotik; manipulation; datorseende; maskininlärning; artificiell intelligens; kognition; Computer Science; Datalogi;

   Sammanfattning : Most of us perform grasping actions over a thousand times per day without giving it much consideration, be it from driving to drinking coffee. Learning robots the same ease when it comes to grasping has been a goal for the robotics research community for decades. LÄS MER

5. 4. Developmental Perspectives on Transfer in Third Language Acquisition

   Författare :Susan Sayehli; Allmän språkvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Third language acquisition; second language acquisition; transfer; developmental stages; elicited imitation; syntax; morphology; psychotypology; cross-linguistic influence;

   Sammanfattning : The aim of this thesis is to examine how learner-general developmental stages in syntax and morphology interact with a language-specific factor, the influence of—or transfer from— the language learner’s first (L1) or previously learned second (L2) language on the acquisition of a third language (L3). It thereby aims to bring together two lines of research whose main concepts—transfer and developmental stages—have often been defined as mutually exclusive and generally studied in separate lines of research.

7. 5. Role of Endogenous BDNF and NT3 for Synaptic Transmission and Plasticity in the Dentate gyrus

   Författare :Klara Olofsdotter; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; dentate gyrus; GABA; glutamate; synaptic transmission; synaptic plasticity; Brain-derived neurotrophic factor; neurotrophin 3; Neurologi; neurophysiology; neuropsychology; Neurology; electrophysiology; neurofysiologi; neuropsykologi;

   Sammanfattning : The neurotrophins, notably brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3), modulate synaptic transmission and synaptic plasticity in the adult mammalian brain. Recent data suggest that neurotrophins might be mediators of activity-dependent synaptic plasticity. LÄS MER
