1. 1. Workload Detection and Continuous Automatic Bayesian Optimization in Database Management Systems

   University essay from Lunds universitet/Institutionen för datavetenskap

   Author : Jonas Boström; Viktor Olsson; [2022]
   Keywords : Technology and Engineering;

   Abstract : The goal of this thesis has been to investigate the possibility of multi-workload optimization in Database Management Systems and workload detection. A system was successfully constructed to allow for multi-workload testing and data aggregation. READ MORE

3. 2. Generation and Detection of Adversarial Attacks for Reinforcement Learning Policies

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

   Author : Axel Drotz; Markus Hector; [2021]
   Keywords : Deep Reinforcement Learning; Adversarial Attacks; Adversarial Attack Detection; Fast Gradient Sign Method; Deep Deterministic Policy Gradient; Deep Q-Learning; Likelihood Ratio Test; CUSUM;

   Abstract : In this project we investigate the susceptibility ofreinforcement rearning (RL) algorithms to adversarial attacks.Adversarial attacks have been proven to be very effective atreducing performance of deep learning classifiers, and recently,have also been shown to reduce performance of RL agents.

4. 3. Abnormality detection in diagnostics data from network cameras

   University essay from Lunds universitet/Matematik LTH

   Author : André Hedesand; Oliver Dageson; [2021]
   Keywords : machine learning; change detection; anomaly detection; data synthesis; forecasting; gradient boost; Mathematics and Statistics;

   Abstract : For data-driven companies, there is a need to efficiently navigate through big quantities of collected data. In our case; detecting changes in the behaviour of data. We have investigated whether machine learning could be applied to automate the process of finding abnormal behaviour (anomalies) in collected data. READ MORE

5. 4. Detection of Long Term Vibration Deviations in GasTurbine Monitoring Data

   University essay from Linköpings universitet/Fordonssystem

   Author : Johan Hansson; [2020]
   Keywords : Machine Learning; Vibrations;

   Abstract : Condition based monitoring is today essential for any machine manufacturer tobe able to detect and predict faults in their machine fleet. This reduces the maintenancecost and also reduces machine downtime. READ MORE

6. 5. Implementation of improved fat standardization using statistical process control

   University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

   Author : Lovisa Bjenning; [2019]
   Keywords : Milk; Whole milk; Semi-skimmed milk; Fat content; Statistical process control; MilkoScan FT2;

   Abstract : The aim of this project was to apply statistical process control (SPC) and measure the variation of fat content in milk in order to improve the standardization, so that the fat content does not change more than 0.03 percentage units from target. Recommendations of how to adjust the standardization should also be developed. READ MORE
