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

    Author : Povel Forsare Källman; [2021]
    Keywords : Anomaly Detection; Root Cause Analysis; Cluster Analysis; k- means; Self- Organizing Map; Gaussian Mixture Model; Dimensionality Reduction; Principal Component Analysis; Hybrid Fiber- Coaxial Network.; Anomalidetektering; Rotfelsanalys; Klusteranalys; k- means; Self- Organizing Map; Gaussian Mixture Model; Dimensionsreducering; Principal Component Analysis; Hybrid Fiber Coax- nät.;

    Abstract : Following the significant transition from the traditional production industry to an informationbased economy, the telecommunications industry was faced with an explosion of innovation, resulting in a continuous change in user behaviour. The industry has made efforts to adapt to a more datadriven future, which has given rise to larger and more complex systems. READ MORE

  3. 12. Incorporating Metadata Into the Active Learning Cycle for 2D Object Detection

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

    Author : Karsten Stadler; [2021]
    Keywords : Active learning; Deep Learning; Object detection; Metadata; Nuscenes Nuimages; Gaussian mixture model; Rejection sampling; Monte-Carlo methods; Aktiv Inlärning; Djupinlärning; Objektdetektering; metadata; Nuscenes Nuimages; Gaussisk blandingsmodell; Rejection sampling; Monte-Carlo metoder;

    Abstract : In the past years, Deep Convolutional Neural Networks have proven to be very useful for 2D Object Detection in many applications. These types of networks require large amounts of labeled data, which can be increasingly costly for companies deploying these detectors in practice if the data quality is lacking. READ MORE

  4. 13. VePMAD: A Vehicular Platoon Management Anomaly Detection System : A Case Study of Car-following Mode, Middle Join and Exit Maneuvers

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

    Author : Weaam Bayaa; [2021]
    Keywords : MDS; GMMHMM; PMP; Machine Learning; Bayesian information Criterion BIC ; Platoon Behavior Recognition; MDS; GMMHMM; PMP; Maskininlärnings; BIC; Plutonbeteendeigenkänning;

    Abstract : Vehicle communication using sensors and wireless channels plays an important role to allow exchanging information. Adding more components to allow exchanging more information with infrastructure enhanced the capabilities of vehicles and enabled the rise of Cooperative Intelligent Transport Systems (C-ITS).

  5. 14. Audio Detection for Preparation of Video Rate Controller

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Olle Axelsson; Tobias Bladh; [2021]
    Keywords : Audio detection; Gaussian Mixture Model; GMM; Video Rate Control; Rate Control; Video Streaming; Technology and Engineering;

    Abstract : Modern video streaming may use the protocol H.264 to encode video in high quality. The protocol takes advantage of similarities between consecutive frames to lower the bit rate. If there are differences between frames the bit rate will therefore rise. READ MORE

  6. 15. Use of Thermal Imagery for Robust Moving Object Detection

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Hannah Bergenroth; [2021]
    Keywords : Moving object detection; background subtraction; convolutional neural network; image fusion;

    Abstract : This work proposes a system that utilizes both infrared and visual imagery to create a more robust object detection and classification system. The system consists of two main parts: a moving object detector and a target classifier. READ MORE
