1. 21. Enhancing person re-identification: leveraging DensePose for improving occlusion handling and generalization

   University essay from Lunds universitet/Matematik LTH

   Author : Björn Elwin; Anton Fredriksson; [2023]
   Keywords : Mathematics and Statistics;

   Abstract : In this master’s thesis we propose a DensePose-based person re-identification (re-ID) machine learning algorithm building upon previous research on this topic. DensePose, a deep neural network that performs human body part segmentation on images, forms the foundation of our approach. READ MORE

3. 22. Methods for Co-Orbital Threat Assessment in Space

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

5. 24. 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.

6. 25. Translation strategies for figurative language in non-fiction : Translating metaphors, idioms, and phrasal verbs from English to Swedish

   University essay from Linnéuniversitetet/Institutionen för språk (SPR)

   Author : Vicky Taylor; [2022]
   Keywords : figurative language; translation; conceptual metaphors; idioms; phrasal verbs; translation strategies; literal translation; transference; meaning translation; omission; addition; Swedish; English;

   Abstract : This thesis examines translation strategies for translating figurative language with a focus on metaphors, idioms, and phrasal verbs. Translators often state that figurative language presents challenges in the translation process. This is mainly because the translator must consider the language’s pragmatic, cognitive, and aesthetic functions. READ MORE
