2020 arXiv   pre-print
On the other hand, for regression tasks, we evaluated three ML and four DL-based regressors.  ...  The best arrangements achieved accuracies of 96.15%, 93.02%, and 87.80% for typing style, gender, and major/minor, respectively, and mean absolute errors of 1.77 years and 2.65 inches for age and height  ...  Likewise, Li et al. ] analyzed stylometry and keystroke dynamics to predict the gender of the person from 15 minutes of chat with 72% accuracy.

Ranking to Learn and Learning to Rank: On the Role of Ranking in Pattern Recognition Applications [article]

Giorgio Roffo
2017 arXiv   pre-print
For example, in pattern classification tasks, different data representations can complicate and hide the different explanatory factors of variation behind the data.  ...  In such a case feature selection is used, that, by producing ranked lists of features, helps to filter out the unwanted information.  ...  Data needed to analyze keystroke dynamics is obtained by keystroke logging.  ...

We propose a candidate ranking model for "this-issue" anaphora resolution that explores different "issue"-specific and general abstract-anaphora features. The model is not restricted to nominal  ...  To maximize the utility of the injected knowledge, we deploy a learning-based multi-sieve approach and develop novel entity-based features.  ...  We exploit the latent semantic information among users, topics, and social connections as features for prediction. Our framework is evaluated on real data collected from public domain.  ...
