  1. 1. Finding Causal Relationships Among Metrics In A Cloud-Native Environment

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

    Författare :Suresh Rishi Nandan; [2023]
    Nyckelord :Causality; Causal Discovery; Bayesian Network; Conditional Independence; Partial Correlation; Ensemble Causal Discovery; Anomaly Detection; Causal Graphs; Causality; Causal Discovery; Bayesian Network; Conditional Indeberoende; partiell korrelation; Ensemble Causal Discovery; Anomali Detektion; kausala grafer;

    Sammanfattning : Automatic Root Cause Analysis (RCA) systems aim to streamline the process of identifying the underlying cause of software failures in complex cloud-native environments. These systems employ graph-like structures to represent causal relationships between different components of a software application. LÄS MER

  3. 2. Towards Causal Discovery on EHR data : Evaluation of current Causal Discovery methods on the MIMIC-IV data set

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

    Författare :Pontus Olausson; [2022]
    Nyckelord :Causal Discovery; Time-Series; MIMIC-IV; EHR; Kasual Upptäckt; Tidsserier; MIMIC-IV; elektroniska patientjournaler;

    Sammanfattning : Causal discovery is the problem of learning causal relationships between variables from a set of data. One interesting area of use for causal discovery is the health care domain, where application could help facilitate a better understanding of disease and treatment mechanisms. LÄS MER

  4. 3. Selection of Sufficient Adjustment Sets for Causal Inference : A Comparison of Algorithms and Evaluation Metrics for Structure Learning

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Agnes Widenfalk; [2022]
    Nyckelord :Causal Inference; Structure Learning; PC-algorithm; Covariate Selection; Causal Graphs;

    Sammanfattning : Causal graphs are essential tools to find sufficient adjustment sets in observational studies. Subject matter experts can sometimes specify these graphs, but often the dependence structure of the variables, and thus the graph, is unknown even to them. In such cases, structure learning algorithms can be used to learn the graph. LÄS MER

  5. 4. Security Countermeasure Selection as a Constraint Solving Problem

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Aya Kathem; [2021]
    Nyckelord :Logical attack graph; Optimization problem; Constraint Solving Problems; Computer Network Security.;

    Sammanfattning : Network systems often contain vulnerabilities that remain unmitigated in a network for various reasons, such as lack of a patch and limited budget. Adversaries can exploit these existing vulnerabilities through different strategies. LÄS MER

  7. 5. The Environmental Effects of Investing in ICT - Evidence from Sweden

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Lisa Grabo; [2021]
    Nyckelord :environment; emission; ICT; technology; distributed-lag model and event study.; Business and Economics;

    Sammanfattning : The potential of Information and Communication Technology (ICT) to reduce greenhouse gas emissions has been increasingly acknowledged as relevant in intergovernmental policy documents. However, the positive and negative environmental effects of ICTs are widely debated and there is a lack of systematic analysis regarding causal links between ICT and the environment. LÄS MER
