1. 1. Detection and Analysis of Anomalies in Tactical Sensor Systems through Structured Hypothesis Testing

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

   Author : Fredrik Ohlson; [2023]
   Keywords : Tactical sensor systems; Sensor fusion; Model based diagnostics; Hypothesis testing; Taktiska sensor system; Sensor fusion; Modellbaserad diagnostisering; Hypotesprövning;

   Abstract : The project explores the domain of tactical sensor systems, focusing on SAAB Gripen’s sensor technologies such as radar, RWR (Radar Warning Receiver), and IRST (InfraRed Search and Track). The study employs structured hypothesis testing and model based diagnostics to examine the effectiveness of identifying and isolating deviations within these systems. READ MORE

3. 2. Unsupervised Machine Learning Based Anomaly Detection in Stockholm Road Traffic

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

   Author : Vilma Hellström; [2023]
   Keywords : Anomaly detection; DBSCAN; LSTM; Machine learning; Synthetic anomalies; Unsupervised learning; Anomalidetektering; DBSCAN; LSTM; maskininlärning; syntetiska anomalier; oövervakad inlärning;

   Abstract : This thesis is a study of anomaly detection in vehicle traffic data in central Stockholm. Anomaly detection is an important tool in the analysis of traffic data for improved urban planing. Two unsupervised machine learning models are used, the DBSCAN clustering model and the LSTM deep learning neural network. READ MORE

4. 3. Prediction of industrial machine failure by analysing anomalies

   University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

   Author : Md Abdur Rahman Akash; [2022]
   Keywords : ;

   Abstract : The sudden downtime and unplanned maintenance not only drastically increase the maintenance cost but also decreases the production capacity for the manufacturer industries. This is because the machines on these industries fail suddenly and totally stop the production as the machine should be fixed by maintenance before it can run again. READ MORE

5. 4. Conversational Engine for Transportation Systems

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Albin Sidås; Simon Sandberg; [2021]
   Keywords : Natural Language Processing; Topic Classification; Named Entity Classification; NLP; NER; NERC;

   Abstract : Today's communication between operators and professional drivers takes place through direct conversations between the parties. This thesis project explores the possibility to support the operators in classifying the topic of incoming communications and which entities are affected through the use of named entity recognition and topic classifications.

6. 5. A Review of Anomaly Detection Techniques forHeterogeneous Datasets

   University essay from KTH/Optimeringslära och systemteori

   Author : Shirwan Piroti; [2021]
   Keywords : Anomaly Detection; Heterogeneous; GAN; BiGAN; Autoencoder; Random Forest; Isolation Forest; Anomalidetektering; Heterogen; GAN; BiGAN; Autoencoder; Random Forest; Isolation Forest;

   Abstract : Anomaly detection is a field of study that is closely associated with machine learning and it is the process of finding irregularities in datasets. Developing and maintaining multiple machine learning models for anomaly detection takes time and can be an expensive task. One proposed solution is to combine all datasets and create a single model.
