  1. 1. Automating Root Cause Analysis of Anomalies in Ericsson Wallet Platform using Machine Learning

    University essay from Blekinge Tekniska Högskola

    Author : Simron Padhi; Devi Priya Battina; [2023]
    Keywords : Anomaly detection; Isolation forest algorithm; K-means algorithm; Local Outlier Factor algorithm; One class Support Vector Machine;

    Abstract : Background: In this era of mobile wallet platforms, to ensure key requirements like high availability and performance, the company must have mechanisms in place to detect anomalies at any given point in time. Ericsson Wallet Platform(EWP), a mobile wallet platform, is facing the problem of manually analyzing all the logs and reports and taking comprehensive action decisions accordingly. READ MORE

  3. 2. Adaptive random walks on graphs to sample rare events

    University essay from Stockholms universitet/Fysikum

    Author : David Christoph Stuhrmann; [2023]
    Keywords : statistical physics; graphs; random walks; large deviation theory; adaptive power method; dynamical phase transition;

    Abstract : In this thesis, I study fluctuations and rare events of time-additive observables of discrete-time Markov chains on finite state spaces. The observable of interest is the mean node connectivity visited by a random walk running on instances of an Erdős-Rényi (ER) random graph. READ MORE

  5. 4. The State of Software Diversity in the Software Supply Chain of Ethereum Clients

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

    Author : Noak Jönsson; [2022]
    Keywords : Software Supply Chain; Dependency Graphs; Open Source Software; Software Diversity; Ethereum; Blockchain;

    Abstract : The software supply chain constitutes all the resources needed to produce a software product. A large part of this is the use of open-source software packages. READ MORE

  6. 5. Quantum Error Correction Using Graph Neural Networks

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Valdemar Bergentall; [2021-06-17]
    Keywords : Quantum error correction; surface code; graph neural networks;

    Abstract : A graph neural network (GNN) is constructed and trained with a purpose of using it as a quantum error correction decoder for depolarized noise on the surface code. Since associating syndromes on the surface code with graphs instead of grid-like data seemed promising, a previous decoder based on the Markov Chain Monte Carlo method was used to generate data to create graphs.
