  1. 11. Detection of software incidents from large log material with the use of unsupervised machine learning

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : DIMITRIOS ANASTASIADIS; JAKUB LENART; [2022-06-20]
    Keywords : binary classification; log; anomaly detection; machine learning; Local Outlier Factor; Isolation Forest; PCA; LSTM-Autoencoder;

    Abstract : Computer systems generate log files, which contain information on the various operations performed by these systems. This information can support the process of error/failure detection and debugging. Therefore, anomalies can be spotted in the system through its produced log material. READ MORE

  3. 12. Identifying prognostic biomarkers for severe sepsis disease and 28 days mortality

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Gaprielle Massoud; [2022]
    Keywords : ;

    Abstract : Sepsis is a complex, deadly, and difficult-to-diagnose disease characterized by anomalies in numerous life-threatening organ failures caused by an improper host response to an infecting organism such as bacteria, fungi, or viruses. Patient characteristics such as age and immunologic state, infection factors, and environmental factors such as nutritional status affect sepsis prognosis and make it difficult and a common cause of mortality.

  4. 13. Distance preserving Fermat VAE

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

    Author : Miklovana Tuci; [2022]
    Keywords : ;

    Abstract : Deep neural networks takes their strength in the representations, or features, that they internally build. While these internal encodings help networks performing classification or regression tasks on specific data types, it exists a branch of machine learning that has for only purpose to build these representations.

  5. 14. Classifying Electricity Tower Image Data with Unsupervised Curriculum Learning

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Jacob Wedin; [2022]
    Keywords : ;

    Abstract : The core objective of this thesis is to classify a set of aerial photographs into two categories, those containing an electricity tower and those not containing an electricity tower. While supervised deep learning methods can reach excellent results on such tasks, they require large amounts of labeled data. READ MORE

  6. 15. Study of Automated Step Detection Methods and Dwell Time Analysis of Single-Molecule Data : Case of Study: The Turnover of Single Fluorescent ATP on The Active Site of Myosin

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Lathifa Nur Ramdhania; [2022]
    Keywords : Single-molecule; step detection; dwell time analysis;

    Abstract : Single-molecule methods were developed with the objective to obtain kinetic information of biomolecular processes from a single biomolecule. This objective can be achieved by analyzing the binding events in recordings (“trajectories”) of single molecules (e.g., using fluorescence); the so-called dwell times. READ MORE
