  1. 6. Unauthorised Session Detection with RNN-LSTM Models and Topological Data Analysis

    University essay from KTH/Matematik (Avd.)

    Author : Nazar Maksymchuk Netterström; [2023]
    Keywords : Recurrent Neural Network; Long-Short-Term-Memory; Topological Data Analysis; Session based data; Anomaly detection; Time-series analysis; Imbalanced data; Master thesis; Neurala nätverk; Topologisk data analys; Detektion av avvikelse; Sessionsbaserad data; Tidserieanalys; Inbalancerad data; Masteruppsats;

    Abstract : This thesis explores the possibility of using session-based customers data from Svenska Handelsbanken AB to detect fraudulent sessions. Tools within Topological Data Analysis are employed to analyse customers behavior and examine topological properties such as homology and stable rank at the individual level. READ MORE

  3. 7. Regression with Bayesian Confidence Propagating Neural Networks

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

    Author : Raghav Rajendran Bongole; [2023]
    Keywords : Machine Learning; Neural Networks; Brain-like computing; Bayesian Confidence Propagating Neural Networks; Maskininlärning; neurala nätverk; hjärnliknande datorer; Bayesian Förtroendespridande neurala nätverk;

    Abstract : Bayesian Confidence Propagating Neural Networks (BCPNNs) are biologically inspired artificial neural networks. These networks have been modeled to account for brain-like aspects such as modular architecture, divisive normalization, sparse connectivity, and Hebbian learning. READ MORE

  4. 8. Neural functional connections of pragmatics : A potential pragmatic network in development

    University essay from Stockholms universitet/Institutionen för lingvistik

    Author : Ronja Forsgren Roll; [2023]
    Keywords : Pragmatics; development; adolescence; networks; functional connectivity; theory of mind; executive functions; Pragmatik; utveckling; ungdomar; nätverk; funktionell konnektivitet; theory of mind; exekutiva funktioner;

    Abstract : Pragmatic ability is crucial in everyday interactions. In populations of neurotypical individuals, pragmatic skill varies greatly. The neural mechanisms behind the variety, and the neural development of pragmatics remain to be explained. READ MORE

  5. 9. Observability in Machine Learning based Intrusion Detection Systems for RPL-based IoT

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Malin Strand; [2023]
    Keywords : ;

    Abstract : As IoT devices become more and more present in our daily lives, security in IoT networks has become a major concern. A promising approach for detecting attacks is the use of machine learning based Intrusion Detection Systems (IDSs). The attack studied in this thesis is the blackhole attack, an attack causing parts of the network to disconnect. READ MORE

  6. 10. Investigating the Neural Activity Behind Rhythm-Keeping : An Exploratory Mass Univariate Study

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Moses Griffith; [2023]
    Keywords : rhythm; tempo; electroencephalography; mass univariate analysis; cognitive neuroscience;

    Abstract : Many of the skills that are considered noteworthy in our societies are either acquired through training and dedication or granted to those lucky enough to have the right genetics and environment. But one skill that is often overlooked is the ability to keep rhythm. This skill is both remarkable in temporal accuracy and common. READ MORE
