There are many different types of stars in the Universe, from Protostars to Red Supergiants. They can be categorized according to their mass and temperature. Stars are also classified by their spectra (the elements they absorb). Along with their brightness (apparent magnitude), the spectral ...
The formation and the evolution of galaxies is one of the main challenges of this decade and probably of the next one. For most extragalactic studies (photometric and spectroscopic surveys), an a priori information on the galaxy types is necessary for we need a good knowledge of the samples ...

Galaxiesgenerally belong to one of two main types that are readily distinguishable.Spiral galaxiesare young and energetic, filled with the gas needed to form newstars, and sport spiral arms hosting hot, bright stars.Elliptical galaxieshave a much more pedestrian look, their light coming from a un...
The results of morphological galaxy classifications performed by humans and by automated methods are compared. In particular, a comparison is made between the eyeball classifications of 454 galaxies in the Sloan Digital Sky Survey (SDSS) commissioning data (Shimasaku et al. 2001) with those of ...
reason, Jocelyn chose to use astep-wise sequential searchfor feature selection for each of the three model types. In all cases overall classification accuracy was used as th fitness function that drove the search. After feature selection, the classification accuracy of the model on the test set...

This research aims to classify images of different types of galaxies into three more general categories: Elliptical, Spiral and Irregular. The research is based on convolutional neural network, specially using inception. The total number of images that were used in this research were 206 images of...
This dataset contains 9 different seafood types collected from a supermarket in Izmir, Turkey for a university-industry collaboration project at Izmir University of Economics, and this work was published in ASYU 2020. The dataset includes gilt head bream, red sea bream, sea bass, red mullet, ho...
The classification of galaxies has significantly advanced using machine learning techniques, offering deeper insights into the universe. This study focuses on the typology of galaxies using data from the Galaxy Zoo project, where classifications are based on the opinions of non-expert volunteers, introdu...
