Maneesh Sagar, Pavan Chakraborty, Snigdha Sen · 2023
The main objective of the paper is to evaluate the performance of multiple tree-based algorithms on skewed datasets. Although data in astronomical observation is very huge, still in the high redshift zone, it is very less as target values have very few observations in that area, leading to imbalanced distribution of data. For this purpose, we have chosen a redshift dataset from astronomy that contains photometric redshift data in galaxies and quasars in SDSS in the range (0
