  1. 1. Modelling rare events using non-parametric machine learning classiers - Under what circumstances are support vector machines preferable to conventional parametric classiers?

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Lukas Ma; [2021-04-06]
    Keywords : ;

    Abstract : Rare event modelling is an important topic in quantitative social science research. However, despite the fact that traditional classiers based upon general linear models (GLM) might lead to biased results, little attention in the social science community is devoted to methodological studies aimed at alleviating such bias, even fewer of them have considered the use of machine learning methods to tackle analytical problems imposed by rare events.

  2. 2. Anomaly Detection in Log Files Using Machine Learning Techniques

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : Lakshmi Geethanjali Mandagondi; [2021]
    Keywords : Anomaly Detection; Log Files; Machine Learning; Clustering; Outlier Detection;

    Abstract : Context: Log files are produced in most larger computer systems today which contain highly valuable information about the behavior of the system and thus they are consulted fairly often in order to analyze behavioral aspects of the system. Because of the very high number of log entries produced in some systems, it is however extremely difficult to seek out relevant information in these files. READ MORE

  3. 3. Analysing User Viewing Behaviour in Video Streaming Services

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

    Author : Ioannis Markou; [2021]

    Abstract : The user experience offered by a video streaming service plays a fundamental role in customer satisfaction. This experience can be degraded by poor playback quality and buffering issues. These problems can be caused by a user demand that is higher than the video streaming service capacity. READ MORE

  4. 4. Computational Analysis of Swedish Newspapers  Using Topic Detection and Sentiment Analysis

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Simon Wallbing; [2021]
    Keywords : ;

    Abstract : Newspapers might report on the same event, say a sport event or a political statement, but since they most likely differ in the presentation, are the content and under laying message of the articles actually the same? A human can read two separate articles and determine if they touch similar subjects and if they approach the subject in a positive or negative way. If this comparison would be preformed over several thousand of articles a computer would very much be the preferred method. READ MORE

  5. 5. Deployment failure analysis using machine learning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Joosep Franz Moorits Alviste; [2020]
    Keywords : machine learning; log mining; log parsing; pipedrive; deployment failure analysis; failure analysis; classification; log files;

    Abstract : Manually diagnosing recurrent faults in software systems can be an inefficient use of time for engineers. Manual diagnosis of faults is commonly performed by inspecting system logs during the failure time. READ MORE
