1. 1. Deep Reinforcement Learning for Adaptive Human Robotic Collaboration

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Johan Fredin Haslum; [2019]
   Keywords : ;

   Abstract : Robots are expected to become an increasingly common part of most humans everyday lives. As the number of robots increase, so will also the number of human-robot interactions. For these interactions to be valuable and intuitive, new advanced robotic control policies will be necessary. READ MORE

3. 2. Detecting Trends on Twitter : The Effect of Unsupervised Pre-Training

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC); KTH/Skolan för teknikvetenskap (SCI)

   Author : Sandra Bäckström; Johan Fredin Haslum; [2016]
   Keywords : ;

   Abstract : Unsupervised pre-training has recently emerged as a method for initializing super- vised machine learning methods. Foremost it has been applied to artificial neural networks (ANN). Previous work has found unsupervised pre-training to increase accuracy and be an effective method of initialization for ANNs[2]. READ MORE

4. 3. Speaker that uses the non-linearity in air to create sound

   University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

   Author : Johan Fredin; [2005]
   Keywords : Parametric loudspeaker; Difference frequency generation; Biharmonic boundary condition; Nonlinear acoustics;

   Abstract : The aim of this work was to investigate theoretically and experimentally the fact that it is possible to create sound by using the nonlinearity in air. A speaker was built verifying the theory that if at least two high frequencies at high amplitude is propagating through a nonlinear medium, for example air, the difference frequency of these two is created in mid air.
