1. 1. An approach to automate accident scenario generation using recurrent neural networks

   Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Ludvig Oliver Gee; Ian Rhys Jenkins; [2019-11-26]
   Nyckelord :Machine Learning; Recurrent Neural Networks; Active Safety Systems; Scenario Generation; Testing; Time Series Prediction;

   Sammanfattning : There is a need to improve the test procedure of Active Safety Systems through the automation of scenario generation, especially accident scenarios that are critical for testing. The purpose of this thesis is to provide an approach to automate the test generation process using machine learning. LÄS MER

3. 2. City Safety Event Classification using Machine Learning

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Natalia Jurczynska; [2019-11-21]
   Nyckelord :Data Science; machine learning; time series analysis; binary classification; data pre-processing; feature engineering; thesis;

   Sammanfattning : City safety technology aims to reduce vehicle collisions using activated warningsand braking based on automated detection of environmental threats. However, automaticdetection of tentative collisions may differ from driver perception, leadingto false positive activations. LÄS MER

4. 3. Machine Learning for Suicide Risk Assessment on Depressed Patients

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :ARNAUD MOULIS; [2019-11-21]
   Nyckelord :Suicide Risk Assessment; Suicide Detection; Machine Learning; Support Vector Machine;

   Sammanfattning : Suicide is a global phenomena and the leading cause of death in some countriesand age groups, accounting for nearly 1 million deaths and 10 million attempts peryear. It costs society a substantial amount of money both directly and indirectly notto mention the tremendous amount of emotional distress and pain for families andfriends. LÄS MER

5. 4. Department of Computer Science and Engineering UNIVERSITY OF GOTHENBURG CHALMERS UNIVERSITY OF TECHNOLOGY Gothenburg, Sweden 2018 Statistical Model Update Optimization in Industrial Practice

7. 5. Elaborate Operational Requirements to Address Reward Hacking in Reinforcement Learning Agents

   Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Sina Yaghoobzadehtari; Colin Owusu Adomako; Siavash Paidar; [2019-11-18]
   Nyckelord :;

   Sammanfattning : Autonomous agents, in recent times have been used to addressseveral problems, but these agents in their course of achievingtheir task also emit side effects to the environment in which theyoperate. Paramount of these side effects is reward hacking. Inthis report, we try to address reward hacking using elaborateoperational requirements. LÄS MER
