WebClassification on these systems is fairly robust; experienced observers generally agree on a galaxy's Hubble type to a level D T = 0.7 on the scale where the range from, say, Sa to Sab is one unit (and automated systems can be trained to a similar level). So what is this system "telling" us? The Hubble type (or T) can be shown to correlate with: WebIn this project, Galaxy Image Classification using a Deep Convolution Neural Network is presented. The galaxy can be classified based on its features into three main categories, namely: Elliptical, Spiral, and Irregular. The proposed deep galaxy architecture consists of one input convolutional layer having 16 filters, followed by 3 hidden ...
