  2. 2. Effect of powder spray drying on catalyst formulation in tablet form

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Kajsa Wahlgren; [2023]
    Keywords : Spray dryer; Catalyst; Powder; Flowability; Chemical engineering; Technology and Engineering;

    Abstract : Heterogenous catalysts consist of a large surface area support material applied with the catalytic active phase, and the activity of a catalyst is often correlated to the surface area per volume. Support materials often need to be processed further to be optimal for specific processes. READ MORE

  3. 3. Artificial Neural Networks and Inductive Biases for Multi-Instance Multi-Modal Tabular Data : A Case Study for Default Probability Estimation in Small-to-Medium Enterprise Lending

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

    Author : Gustav Röhss; [2022]
    Keywords : ;

    Abstract : The success of artificial neural networks in homogeneous data domains such as images, textual data, and audio and other signals has had considerable impact on Machine Learning and science in general. The domain of heterogeneous tabular data, while arguably much more common, remains much less explored with regards to artificial neural networks and deep learning. READ MORE

  4. 4. Real-time Anomaly Detection on Financial Data

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

    Author : Anna Martignano; [2020]
    Keywords : Network Representation Learning; Anomaly Detection; Financial Industry; Graph Neural Networks; Dynamic Graphs; Heterogeneous Graphs; Nätverkiskt Representationsinlärning; Avvikelse av Anomali; Finansiell Industri; Grafiskt Neuralt Nätverk; Dynamiska Grafer; Heterogena Grafer;

    Abstract : This work presents an investigation of tailoring Network Representation Learning (NRL) for an application in the Financial Industry. NRL approaches are data-driven models that learn how to encode graph structures into low-dimensional vector spaces, which can be further exploited by downstream Machine Learning applications.
