  12. Conclusion ● 62% agreement between Zooniverse volunteers and experts, however an extremely pure sample of clusters (99% agreement). ● Our hand-made convolutional neural network achieved the best average accuracy, 90%. ● Future plans: - Galaxy cluster catalogue. - Object detection approach. - Utilisation of other wavelengths, radio, infrared and/or SZ effect. - Conducting cosmological studies. 14/14
