  1. 1. 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.

  2. 2. An Industrial Application of Semi-supervised techniques for automatic surface inspection of stainless steel. : Are pseudo-labeling and consistency regularization effective in a real industrial context?

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

    Author : Mattia Zoffoli; [2022]
    Keywords : Deep Learning; Computer Vision; Semi-Supervised Learning; Automatic Inspection; Stainless Steel; Djupt lärande; datorseende; Semi-övervakat lärande; Automatisk inspektion; Rostfritt stål;

    Abstract : Recent developments in the field of Semi-Supervised Learning are working to avoid the bottleneck of data labeling. This can be achieved by leveraging unlabeled data to limit the amount of labeled data needed for training deep learning models. READ MORE

  3. 3. Defect classification in LPBF images using semi-supervised learning

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Author : Anton Göransson; [2022]
    Keywords : Additive manufacturing; Laser powder bed fusion; Machine learning; Siamese neural networks; Deep learning; Defect classification;

    Abstract : Laser powder bed fusion is an additive manufacturing technique that is capable of building metallic parts by spreading many layers of metal powder over a build surface and using a laser to melt specific sections of the surface. The part is built by melting consecutive layers on top of each other until the design is completed. READ MORE

  4. 4. Automated Extraction of Data from Insurance Websites

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

    Author : Amar Hodzic; [2022]
    Keywords : Insurance; Semi-structured data; Web data extraction; Deep learning; Försäkring; Semistrukturerad data; Webbdataextraktion; Djupinlärning;

    Abstract : Websites have become a critical source of information for many organizations in today's digital era. However, extracting and organizing semi-structured data from web pages from multiple websites poses challenges. This is especially true when a high level of automation is desired while maintaining generality. READ MORE

  5. 5. A Systematic Study of Semi-Supervised Learning Based on Shapley Value Data Valuation

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Christie Courtnage; [2022]
    Keywords : ;

    Abstract : Semi-supervised learning algorithms seek to train prediction models on both labelled and unlabelled that outperform prediction models trained only on labelled data. Semi-supervised learning is often realised through the selection of unlabelled instances with predicted pseudo-labels. READ MORE
