We use this positional information to overlay a colored mask over the text that corresponds to the position in the ranking. A word that ranks within the most likely words is highlighted in green (top 10), yellow (top 100), red (top 1,000), and the rest of the words in purple. Thus, we can get a direct visual indication of how likely each word was under the model.Starting Price: Free -
