Uploaded by Levi

Thesis materials on improving photometric redshifts using a synergy between template-based approaches and machine learning methods. The work situates the research within a structured doctoral framework, beginning with an introduction that states the problem, research objectives, thesis contributions, and overall outline. A literature review covers galaxies, cosmological redshifts, photometric redshift, template-based photo-z methods, machine learning methods, and a comparison between template fitting and machine learning, followed by a review of synergetic methods. The methodology section introduces data samples and the proposed research process.
