Learning to Estimate Driver Drowsiness from Car Acceleration Sensors using Weakly Labeled Data
This paper addresses the learning task of estimating driver drowsiness from
the signals of car acceleration sensors. Since even drivers themselves cannot
perceive their own drowsiness in a timely manner unless they use burdensome
invasive sensors, obtaining labeled training data for each timestamp is not a
realistic goal. To deal with this difficulty, we formulate the task as a weakly
supervised learning. We only need to add labels for each complete trip, not for
every timestamp independently. By assuming that some aspects of driver
drowsiness increase over time due to tiredness, we formulate an algorithm that
can learn from such weakly labeled data. We derive a scalable stochastic
optimization method as a way of implementing the algorithm. Numerical
experiments on real driving datasets demonstrate the advantages of our
algorithm against baseline methods.Comment: Accepted by ICASSP202
Exploratory study to explore the role of ICT in the process of knowledge management in an Indian business environment
In the 21st century and the emergence of a digital economy, knowledge and the knowledge base economy are rapidly growing. To effectively be able to understand the processes involved in the creating, managing and sharing of knowledge management in the business environment is critical to the success of an organization. This study builds on the previous research of the authors on the enablers of knowledge management by identifying the relationship between the enablers of knowledge management and the role played by information communication technologies (ICT) and ICT infrastructure in a business setting. This paper provides the findings of a survey collected from the four major Indian cities (Chennai, Coimbatore, Madurai and Villupuram) regarding their views and opinions about the enablers of knowledge management in business setting. A total of 80 organizations participated in the study with 100 participants in each city. The results show that ICT and ICT infrastructure can play a critical role in the creating, managing and sharing of knowledge in an Indian business environment
