  1. 1. Machine Learning for Detecting Hate Speech in Low Resource Languages

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : David Rodriguez; Denitsa Saynova; [2020-07-08]
    Keywords : machine learning; natural language processing; BERT; cross-lingual zeroshot learning; data augmentation; hate speech; classification; Twitter;

    Abstract : This work examines the role of both cross-lingual zero-shot learning and data augmentationin detecting hate speech online for low resource set-ups. The proposedsolutions for situations where the amount of labeled data is scarce are to use alanguage with more resources during training or to create synthetic data points. READ MORE

  2. 2. Training a Neural Network using Synthetically Generated Data

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

    Author : Fredrik Diffner; Hovig Manjikian; [2020]
    Keywords : Synthetic data set; Generating synthetic data set; Machine learning; Deep Learning; Convolutional Neural Networks; Machine learning model; Character recognition in natural images; Char74k; ICDAR2003.; Syntetiskt dataset; Generera syntetiskt data; Maskininlärning; Maskininlärningsmodell; Djuplärning; Konvolutionära neurala nätverk; teckenigenkänning i bilder; Char74k; ICDAR2003;

    Abstract : A major challenge in training machine learning models is the gathering and labeling of a sufficiently large training data set. A common solution is the use of synthetically generated data set to expand or replace a real data set. READ MORE

  3. 3. Volatility- An investigation of the relationship between price- and yield volatility

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Samia Nasir; [2020]
    Keywords : Price Volatility; Yield Volatility; Python; Bonds; Zero-Coupon rate; COVID-19;

    Abstract : This report investigates the relationship between the yield volatility and the price volatility in the Swedish market. The method given in our report can be used to analyze any market with appropriate data set. We have used a time-series data of interest rate yield curves from Swedish government bonds. READ MORE

  4. 4. Analysis of stellar spectra with machine learning

    University essay from Lunds universitet/Institutionen för teoretisk fysik; Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Alvaro Segovia Otero; [2020]
    Keywords : Galactic Archaeology; machine learning; chemical abundances; FGK stars; Physics and Astronomy;

    Abstract : Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. READ MORE

  5. 5. Evaluation of Camera Resolution in Optical Flow Estimation Using Event-Based Cameras

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

    Author : Simon Hellberg; Dominik Hollidt; [2020]
    Keywords : ;

    Abstract : Developments in event-based camera technology and their recent increase in pixel count raised the question of whether resolution helps the accuracy and performance of algorithms. This thesis studies the impact of resolution on optical flow estimation for event-based cameras. READ MORE
