The overall accuracy of the algorithm was 83% and 81% respectively, the researchers said.<\/p>\n<p>According to them, the method&#8217;s advantages are its speed and its ability to generalise.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cAlthough training a CNN may be a costly undertaking in terms of computational power, the speed of galaxy classification after training is several orders of magnitude higher than manual processing,\u201d the study says.<\/p>\n<\/blockquote>\n<p>The neural network could classify more than 100 million galaxies at various distances from Earth and in different environments, they added.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cBut if you put a group of astronomers in a room and ask them to classify several images, there will almost certainly be disagreements. This inherent uncertainty is a limiting factor in any AI model trained on labeled data,\u201d he says.<\/p>\n<\/blockquote>\n<p>Cavana added that the method could deepen understanding of how galaxies transform over time.
