A survey of ground-truth in emotion data annotation

Layale Constantine, Hazem Hajj
2012 2012 IEEE International Conference on Pervasive Computing and Communications Workshops  
This paper aims to solve the problem of lack of ground-truth in emotion data and consequently to advance the accuracy of emotion recognition systems.  ...  Then, it digs in deep into the data acquisition and annotation stage and reveals the major criteria for obtaining a ground-truth emotion set.  ...  The lack of ground-truth occurs in the training data collected where the validity of the labels provided for each measurement is doubtful.  ...

How Laboratory Experiments Can Be Exploited for Monitoring Stress in the Wild: A Bridge Between Laboratory and Daily Life

Can, Gokay, Kılıç, Ekiz, Chalabianloo, Ersoy
2020 Sensors  
We investigated the effect of different labeling techniquesand different training and test environments.  ...  However, the performance of these systems is notsufficiently accurate when they are used in unrestricted daily life compared to the systems testedin controlled real-life and laboratory conditions.  ...  However, for everyday life, the self-reports are the closest labels to the ground truth.  ...

We get the algorithms of our ground truths: Designing referential databases in digital image processing

Florian Jaton
2017 Social Studies of Science  
In the project being studied, problematization processes lead to the constitution of referential databases called 'ground truths' that enable both the effective shaping of algorithms and the evaluation  ...  Working as important common touchstones for research communities in image processing, the ground truths are inherited from prior problematization processes and may be imparted to subsequent ones.  ...  Acknowledgements I am immensely grateful to the members of the computer science laboratory who let me follow their activities and more generally helped me with the research.  ...
