    Sammanfattning : In the 21st century, information is the new currency. With the omnipresence of devices connected to the internet, humanity can instantly avail any information. However, there are certain are cybercrime groups which steal the information. LÄS MER

  2. 2. Hybrid Extended Isolation Forest : Anomaly Detection for Bird Alarm

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Viktor Holmér; [2019]
    Nyckelord :;

    Sammanfattning : The Isolation Forest algorithm is a random forest based anomaly detection algorithm utilizing isolation to determine anomality of data. The Hybrid Isolation Forest and Extended Isolation Forest algorithms were independently developed to overcome two separate issues with the Isolation Forest algorithm. LÄS MER

  3. 3. 3D Modelling of TEM Data : from Rajapalot Gold-Cobalt prospect, northern Finland

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Niklas Torikka; [2019]

    Sammanfattning : The Rajapalot gold-cobalt project in northern Finland is an exciting, relatively new discovery, still being explored with hopes to start mining in the future. The area was found by a IP/Resistivity survey in 2013. LÄS MER

  4. 4. Anomaly Detection in Streaming Data from a Sensor Network

    Master-uppsats, KTH/Matematisk statistik

    Författare :Egill Vignisson; [2019]
    Nyckelord :Anomaly Detection; Sequential Data; Semi-supervised Learning; Recurrent Neural Network; Applied Mathematics; Anomalidetektion; sekventiell data; halv-övervakad maskininlärning; återkommande neuralt nätverk; tillämpad matematik.;

    Sammanfattning : In this thesis, the use of unsupervised and semi-supervised machine learning techniques was analyzed as potential tools for anomaly detection in the sensor network that the electrical system in a Scania truck is comprised of. The experimentation was designed to analyse the need for both point and contextual anomaly detection in this setting. LÄS MER
