  1. 1. A computational model of metapopulation dynamics and organism-mediated nutrient flow

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Amanda Hansson; [2023-08-07]
    Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

    Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.

  2. 2. Domain Knowledge and Representation Learning for Centroid Initialization in Text Clustering with k-Means : An exploratory study

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

    Author : David Yu; [2023]
    Keywords : Natural language processing; Sentiment analysis; Clustering; Language model; Transformer; Heuristic; Språkteknologi; Sentimentanalys; Klustering; Språkmodell; Transformer; Heuristik;

    Abstract : Text clustering is a problem where texts are partitioned into homogeneous clusters, such as partitioning them based on their sentiment value. Two techniques to address the problem are representation learning, in particular language representation models, and clustering algorithms. READ MORE

  3. 3. Predicting the Unpredictable – Using Language Models to Assess Literary Quality

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Yaru Wu; [2023]
    Keywords : perplexity; variance; unpredictability; homogeneity; generative pre-trained models; text generation; literary quality;

    Abstract : People read for various purposes like learning specific skills, acquiring foreign languages, and enjoying the pure reading experience, etc. This kind of pure enjoyment may credit to many aspects, such as the aesthetics of languages, the beauty of rhyme, and the entertainment of being surprised by what will happen next, the last of which is typically featured in fictional narratives and is also the main topic of this project.

  4. 4. 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

  5. 5. Investigation of case hardened steel subjected to torsion: An experimental and numerical elastic-plastic material study

    University essay from KTH/Hållfasthetslära

    Author : Jonathan Fridstrand; [2022]
    Keywords : Torsion; Shear stress-strain relation; Elastoplastic material; Case hardened steel; Custom material model; Vridning; Skjuvtöjning och -spänning; Elastiskt-plastiskt material; Sätthärdat stål; Anpassad materialmodell;

    Abstract : There is currently a knowledge gap regarding the plastic material properties of many steel types that Atlas Copco use in their high torque power tools. This makes it difficult to fully utilise the capabilities of the Finite Element Method (FEM) to aid the developmental process. READ MORE
