  1. 11. Machine learning to detect anomalies in datacenter

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Filip Lindh; [2019]
    Keywords : machine learning; anomaly detection; server; support vector machine; performance data;

    Abstract : This thesis investigates the possibility of using anomaly detection on performance data of virtual servers in a datacenter to detect malfunctioning servers. Using anomaly detection can potentially reduce the time a server is malfunctioning, as the server can be detected and checked before the error has a significant impact. READ MORE

  3. 12. Paleoclimate reconstructionfrom climate proxiesby neural methods

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Marie Déchelle-Marquet; [2019]
    Keywords : sparse reconstruction; GCM; self-organizing maps; recurrent neural networks; climate natural variability;

    Abstract : In the present work, we investigate the capacity of machine learning to reconstruct simulated large scale surface temperature anomalies given a sparse observation field. Several methods are combined: self-organizing maps and recurrent neural networks of the temporal trajectory. READ MORE

  4. 13. Using Self-Organizing Maps to Identify Operational Risk

    University essay from Lunds universitet/Matematisk statistik

    Author : Lukas Ljungblom; Jonatan Berggren; [2018]
    Keywords : Self-organizing Map; Machine Learning; Neural Network; Clustering; Operational Risk; Audit Change; Mathematics and Statistics;

    Abstract : In recent years, the awareness and concern for operational risk in financial institutions have increased, and several disastrous events in the last two decades been caused by human error. With this, the regulatory demands have increased on the financial institutions to control operational risk. READ MORE

  5. 14. A comparative study on a practical use case for image clustering based on common shareability and metadata

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

    Author : Erik Dackander; [2018]
    Keywords : clustering; cluster analysis; machine learning; degoo; image clustering; comparative study; klustring; klusteranalys; maskininlärning; degoo; bildklustring; jämförande studie;

    Abstract : As the amount of data increases every year, the need for effective structuring of data is a growing problem. This thesis aims to investigate and compare how four different clustering algorithms perform on a practical use case for images. READ MORE

  6. 15. Investigating the Potential of Using SOM on Audit Changed Trades

    University essay from KTH/Teknisk informationsvetenskap

    Author : Thomas Montzka; [2018]
    Keywords : ;

    Abstract : During the last 20 years, operational risk has been identified as an considerablerisk that needs to be tracked and handled, particular in the financial industry.The Basel Committee on banking supervision is a global cooperation thatsets standard regulations for banking corporations.
