Advanced Astroinformatics for Variable Star Classification
TLDR
It is proposed that a complete machine learning strategy for use in the upcoming era of big data from the next generation of big telescopes, such as LSST, must consider this type of design integration.
Automatic Survey-invariant Classification of Variable Stars
TLDR
A full Probabilistic model is proposed that represents the joint distribution of features from two surveys as well as a probabilistic transformation of the features between one survey to the other and to effectively run a variable star classification model in a new survey.
On the use of logistic regression for stellar classification
TLDR
An alternative supervised classification method scarcely exploited in astronomy, Logistic Regression, that has been applied successfully in other scientific areas, particularly biostatistics is applied in this article in order to derive membership probabilities for potential T Tauri star candidates from ultraviolet-infrared colour-colour diagrams.

Population Based Meta Heuristics Algorithm for Performance Improvement of Feed Forward Neural Network
TLDR
The proposed algorithm based on water cycle that includes the evaporation, condensation and precipitation (WC-ECP), which is a population based metaheuristic is used in the paper to improve the accuracy in the feed forward neural network (PNN-probabilistic neural network) and improvise the accuracy of the categorization and the speed of the convergence.
Self-taught Learning: Image Classification Using Stacked Autoencoders
TLDR
Rigorous experiments show that the self-taught learning approach is doing well against the baseline model (where no transfer learning has been used) even when there are limited number of labeled data instances in the target domain.
