• Title: On the Inference of Soft Biometrics from Typing Patterns Collected in a Multi-device Environment
• Authors: Vishaal Udandarao and Mohit Agrawal and Rajesh Kumar and Rajiv Ratn Shah
• Abstract summary: In this paper, we study the inference of gender, major/minor, typing style, age, and height from the typing patterns collected from 117 individuals in a multi-device environment. For classification tasks, we benchmark the performance of six classical machine learning (ML) and four deep learning (DL) classifiers. The results are promising considering the variety of application scenarios that we have listed in this work.

• Abstract: In this paper, we study the inference of gender, major/minor (computer science, non-computer science), typing style, age, and height from the typing patterns collected from 117 individuals in a multi-device environment. The inference of the first three identifiers was considered as classification tasks, while the rest as regression tasks. For classification tasks, we benchmark the performance of six classical machine learning (ML) and four deep learning (DL) classifiers. On the other hand, for regression tasks, we evaluated three ML and four DL-based regressors. The overall experiment consisted of two text-entry (free and fixed) and four device (Desktop, Tablet, Phone, and Combined) configurations. 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, respectively. The results are promising considering the variety of application scenarios that we have listed in this work.

  We show that it is possible to achieve significant improvements in performance if both the category-based and the object-identity-based embeddings are learned simultaneously during training. This paper presents an attention-based dual-encoder architecture with specially designed loss functions that optimize the inter- and intra-class distances. We demonstrate the power of our approach with three challenging multi-view datasets.
