1. 16. Semi-supervised Sentiment Analysis for Sentence Classification

   University essay from Uppsala universitet/Institutionen för lingvistik och filologi

   Author : Eirini Tsakiri; [2022]
   Keywords : sentiment analysis; text classification; semi-supervised learning; machine learning;

   Abstract : In our work, we deploy semi-supervised learning methods to perform Sentiment Analysis on a corpus of sentences, meant to be labeled as either happy, neutral, sad, or angry. Sentence-BERT is used to obtain high-dimensional embeddings for the sentences in the training and testing sets, on which three classification methods are applied: the K-Nearest Neighbors classifier (KNN), Label Propagation, and Label Spreading.

3. 17. A comparative evaluation of machine learning models for engagement classification during presentations : A comparison of distance- and non-distance-based machine learning models for presentation classification and class likelihood estimation

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

   Author : Rebwar Ali Omer Bajallan; [2022]
   Keywords : Audience engagement; Engagement quantification; Machine learning; Distance-based models; Few-shot learning; Statistical analysis; Publiksengagemang; Engagemangskvantifiering; Maskininlärning; Distansbaserade modeller; Few-shot inlärning; Statistisk analys;

   Abstract : In recent years, there has been a significant increase in the usage of audience engagement platforms, which have allowed for engaging interactions between presenters and their audiences. The increased popularity of the platforms comes from the fact that engaging and interactive presentations have been shown to improve learning outcomes and create positive presentation experiences.

4. 18. Evaluation of Error Metrics Used for Quality Assessment of Simplified Meshes

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Dennis Udd; [2022]
   Keywords : Level of Detail; Error Metric; Mesh Comparing; Mesh Simplification; 3D Optimisation; Computer Graphics; LOD;

   Abstract : Level of Detail (LOD) is an important area in game development and it is a term used to describe the complexity of 3D models. Complex 3D models that are rendered from a far distance can often be simplified, to minimise rendering costs. The visual appearance of a simplified model should be as close to the original model as possible. READ MORE

5. 19. A comparison of different methods in their ability to compare semantic similarity between articles and press releases

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

   Author : Julius Andersson; [2022]
   Keywords : Semantic similarity; TF-IDF; SBERT; Cosine similarity; Soft-cosine similarity; Sentence mover’s distance; Semantisk likhet; TF-IDF; SBERT; Cosinus likhet; Mjuk-cosinus likhet; Sentence mover’s distance;

   Abstract : The goal of a press release is to have the information spread as widely as possible. A suitable approach to distribute the information is to target journalists who are likely to distribute the information further. READ MORE

6. 20. Geometric comparison of 3D city models for daylight simulations

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Johannes Lande Nyborg; [2022]
   Keywords : Geography; Physical Geography; Ecosystem Analysis; 3D city model; 3D building models; daylight access; daylight simulations; obstruction angle; free and open-source software; sustainable urban development; Geomatics; Earth and Environmental Sciences;

   Abstract : As cities keep densifying, essential resources such as daylight access become increasingly restricted. Therefore, prioritizing energy efficiency and enhancing the energy performance of our buildings is required for obtaining a sustainable urban environment. READ MORE
