  1. 1. Lakehouse architecture forsimplifying data sciencepipelines

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Nicolas Martin; [2023]
    Nyckelord :;

    Sammanfattning : Data management and pre-processing often consume the majority of time spent by datascientists. The data architecture and the configuration of data pipelines significantly influencethe efficiency of this work. LÄS MER

  3. 2. Decoding communication of non-human species - Unsupervised machine learning to infer syntactical and temporal patterns in fruit-bats vocalizations.

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Luigi Assom; [2023]
    Nyckelord :animal decision making; unsupervised machine learning; UMAP; autoencoders; classifiers; bioacoustics; combinatory syntax; animal communication;

    Sammanfattning : Decoding non-human species communication offers a unique chance to explore alternative intelligence forms using machine learning. This master thesis focuses on discreteness and grammar, two of five linguistic areas machine learning can support, and tackles inferring syntax and temporal structures from bioacoustics data annotated with animal behavior.

  4. 3. CondBEHRT: A Conditional Probability Based Transformer for Modeling Medical Ontology

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Linus Lerjebo; Johannes Hägglund; [2022]
    Nyckelord :Artificial Intelligence; Explainable AI; Machine Learning; Deep Learning; Data Mining; Electronic Health Records; Transformer; Graph Neural Network; Natural Language Processing; Hypertension; Kidney Disease; Heart Failure; Medical Ontology;

    Sammanfattning : In recent years the number of electronic healthcare records (EHRs)has increased rapidly. EHR represents a systematized collection of patient health information in a digital format. EHR systems maintain diagnoses, medications, procedures, and lab tests associated with the patients at each time they visit the hospital or care center. LÄS MER

  5. 4. Czekanowski’s Clustering : Development of Visualization Possibilities of the RMaCzek Package

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Ying Luo; [2022]
    Nyckelord :Cluster Analysis; Graph Visualization; Czekanowski’s Diagram; Seriation Methods; Changing Points Detection;

    Sammanfattning : As one of the most essential data mining tasks, clustering analysis has been widely discussed and employed since its invention. Czekanowski’s diagram, which has been around for over a century as a visualization tool for exploring cluster distributions, is being improved continually. LÄS MER

  7. 5. Pre-training a knowledge enhanced model in biomedical domain for information extraction

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Xi Yan; [2022]
    Nyckelord :bio-nlp; knowledge enhanced language model; pre-training; information extraction. transformer;

    Sammanfattning : While recent years have seen a rise of research in knowledge graph enrichedpre-trained language models(PLM), few studies have tried to transfer the work to the biomedical domain. This thesis is a first attempt to pre-train a large-scalebiological knowledge enriched language model (KPLM). Under the frameworkof CoLAKE (T. Sun et al. LÄS MER
