   Sammanfattning : Neural network models such as Transformer-based BERT, mBERT and RoBERTa are achieving impressive performance (Devlin et al., 2019; Lewis et al., 2020; Liu et al., 2019; Raffel et al. LÄS MER

3. 2. Visualization of Relationships in Clustered Text Data

   Magister-uppsats, Institutionen för datavetenskap (DV)

   Författare :Jiayi Liu; [2013]
   Nyckelord :information visualization; text; clustering; relationship; networks; tag clouds; edge bundling;

   Sammanfattning : There exist lots of text data. They are often extracted into topical tags for indexing. They are also connected by relationships like sharing the same authors, created at the same period. The entirety of above yields a big text network. LÄS MER

4. 3. Visualization of Weather Data : Temperature trend visualization

   Kandidat-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

   Författare :Jiayi Liu; [2012]
   Nyckelord :information visualization; pixel-based approach; temperature; weather;

   Sammanfattning : Weather data are huge. Traditional visualization techniques are limited to show temperature trends. Pixel-based approaches could be used to visualize the huge amount of weather data and in process show the temperature trends. A prototype using this approach is built to make temperature data more understandable in changing trends. LÄS MER
