Machine learning is an automatic learning technique that is revolutionizing the scientific research with innovative applications. The Artificial Neural Networks (ANN) is a powerful and
fast machine learning method often used in astrophysics. Active Galactic Nuclei (AGNs) of uncertain nature have been classified by ANN algorithms based on data collected at gamma-ray
energies when rigorous multiwavelength analysis is not available. In ten years of operation of the Fermi-LAT gamma telescope, the number of uncertain sources has exceeded 50% of the detected sources.
An efficent ANN algorithm can significantly improve the number of classified AGNs in a short time.
We use a TensorFlow Network and we compare our original algorithm against the existing ANNs algorithm used for previous AGN studies in order to improve and optimize the performances an ANN method.
