abstract: >-
The classification of galaxy morphology plays a crucial
role in understanding galaxy formation and evolution.
Traditionally, this process is done manually. The
emergence of deep learning techniques has given room for
the automation of this process. As such, this paper offers
a comparison of deep learning architectures to determine
which is best suited for optical galaxy morphology
classification. Adapting the model training method
proposed by Walmsley et al in 2021, the Zoobot Python
library is used to train models to predict Galaxy Zoo
DECaLS decision tree responses, made by volunteers, using
EfficientNet B0, DenseNet121 and ResNet50 as core model
architectures. The predicted results are then used to
generate accuracy metrics per decision tree question to
determine architecture performance. DenseNet121 was found
to produce the best results, in terms of accuracy, with a
reasonable training time. In future, further testing with
more deep learning architectures could prove beneficial.
