    Sammanfattning : The objective of this paper is to study cluster analysis to identify similarities. To enhance the accuracy of the analysis, two clustering methodologies were employed. LÄS MER

  3. 2. An Application of Cluster Analysis in Identifying and Evaluating Prognostic Subgroups for Therapy-Related Acute Myeloid Leukemia

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Stefanie Antonilli; [2022]
    Nyckelord :AML; lymphoma; heterogeneous data; cluster analysis; k-prototypes algorithm;

    Sammanfattning : Treatment for lymphoma with alkylating therapy is known to increase the risk of secondary malignancies such as Acute Myeloid Leukemia (AML), although the risk is not fully understood. This study investigates the characteristics of AML that arise after lymphoma treatment in contrastto AML cases without a prior lymphoma. LÄS MER

    Sammanfattning : The analysis of gaining, retaining and maintaining customer trust is a highly topical issue in the e-commerce industry to mitigate the challenges of increased competition and volatile customer relationships as an effect of the increasing use of the internet to purchase goods. This study is conducted at the Swedish online fashion retailer NA-KD with the aim of gaining better insight into customer behavior that determines purchases, returns and churn. LÄS MER

  5. 4. Grouping Similar Bug Reports from Crash Dumps with Unsupervised Learning

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

    Författare :Sara Vestergren; [2021]
    Nyckelord :Unsupervised Learning; Bug Report; Duplicate Detection; Clustering; Software Crash; Oövervakad Inlärning; Felrapport; Dublett-detektering; Klustring; Mjukvarukrasch;

    Sammanfattning : Quality software usually means high reliability, which in turn has two main components; the software should provide correctness, which means it should perform the specified task, and robustness in the sense that it should be able to manage unexpected situations. In other words, reliable systems are systems without bugs. LÄS MER

  7. 5. Identification of Phenotypes in Cardiac Arrest Patient Cohorts

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Rebecca Lütz; [2021]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : In this thesis, it is analysed if cardiac arrest patients can be grouped into similar clusters based on different underlying conditions and clinical variables and if there is a difference between clusters in either mortality or neurological outcome as measured by the Cerebral Performance Categories (CPC) scale. The two data sets both contain a targeted temperature management variable which indicates whether or not patients are cooled down upon arrival as well as a variety of continuous and categorical variables.
