  1. 1. And Action! : A Study of the Semantic Domains of Action through Interpretation of Metaphor

    University essay from

    Author : Henrik Westerdahl; [2023]
    Keywords : Semantic domain; Semantic dimension; Semantic pattern; Metaphor; Body in metaphor;

    Abstract : The aim of this essay is determining and describing some of the semantic domains of the concept of action. Action belongs to the type of abstract nouns with unclear semantic domains. In other words, there are difficulties in determining the precise semantic patterns that the word ‘action’ refers to. READ MORE

  3. 2. Messing With The Gap: On The Modality Gap Phenomenon In Multimodal Contrastive Representation Learning

    University essay from Uppsala universitet/Industriell teknik

    Author : Mohammad Al-Jaff; [2023]
    Keywords : Multimodal machine learning; Representation learning; Self-supervised learning; contrastive learning; computer vision; computational biology; bioinformatics;

    Abstract : In machine learning, a sub-field of computer science, a two-tower architecture model is a specialised type of neural network model that encodes paired data from different modalities (like text and images, sound and video, or proteomics and gene expression profiles) into a shared latent representation space. However, when training these models using a specific contrastive loss function, known as the multimodalinfoNCE loss, seems to often lead to a unique geometric phenomenon known as the modality gap.

  4. 3. Urban Uncertainties

    University essay from KTH/Arkitektur

    Author : Josephine Harold; [2022]
    Keywords : Urban development; threshold; Stockholm; continuity; zine; urban planning; city; biodiversity; contamination; appropriation; re-use; alteration; Bergs Hamn; Bergs gård; Nacka; up-cycling; cistern;

    Abstract : Throughout the last decades the linear urban development in Stockholm can be retraced to the idea of supply and demand, society’s view on the elimination of risk, while increasingly detaching from natural processes. This thesis offers a critical evaluation of the socio-economic situation of space production, while trying to argue for a new semantic recodification of urban organisational processes while reconnecting to a socio-biodiverse narrative.

  5. 4. Trade-offs between Quality and Efficiency in Multilingual Dense Retrieval

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

    Author : Emma Schüldt; [2022]
    Keywords : Dense retrieval; Binary Retrieval; Semantic search; ColBERT; Multilingual; MSMarco; Tät informationssökning; Binär informationssökning; Semantisk sökning; ColBERT; Flerspråkig; MS Marco;

    Abstract : As the amount of content online grows, information retrieval becomes increasingly crucial. Traditional information retrieval does not take the text order into account and is also dependent on exact text matching between the query and the document. READ MORE

  6. 5. Radar Detection Using Deep Learning

    University essay from Lunds universitet/Matematik LTH

    Author : Ziliang Xiong; Leonardo Carrera; [2022]
    Keywords : Deep Learning; Autonomous Driving; Radar; Point Cloud; Technology and Engineering;

    Abstract : This thesis aims to reproduce and improve a paper about dynamic road user detection on 2D bird's-eye-view radar point cloud in the context of autonomous driving. We choose RadarScenes, a recent large public dataset, to train and test deep neural networks. READ MORE
