dc.description.abstract | Gamification is known to enhance users’ participation in education and research projects
that follow the citizen science paradigm. The Cosmic Ray Extremely Distributed Observatory
(CREDO) experiment is designed for the large-scale study of various radiation forms that continuously
reach the Earth from space, collectively known as cosmic rays. The CREDO Detector app
relies on a network of involved users and is now working worldwide across phones and other CMOS
sensor-equipped devices. To broaden the user base and activate current users, CREDO extensively
uses the gamification solutions like the periodical Particle Hunters Competition. However, the
adverse effect of gamification is that the number of artefacts, i.e., signals unrelated to cosmic ray
detection or openly related to cheating, substantially increases. To tag the artefacts appearing in the CREDO database we propose the method based on machine learning. The approach involves training
the Convolutional Neural Network (CNN) to recognise the morphological difference between signals
and artefacts. As a result we obtain the CNN-based trigger which is able to mimic the signal vs.
artefact assignments of human annotators as closely as possible. To enhance the method, the input
image signal is adaptively thresholded and then transformed using Daubechies wavelets. In this
exploratory study, we use wavelet transforms to amplify distinctive image features. As a result,
we obtain a very good recognition ratio of almost 99% for both signal and artefacts. The proposed
solution allows eliminating the manual supervision of the competition process. | pl_PL |
