Data-driven approach to Type Ia supernovae: variable selection on the peak luminosity and clustering in visual analytics

Type Ia supernovae (SNIa) have an almost uniform peak luminosity, so that they are used as "standard candle" to estimate distances to galaxies in cosmology. In this article, we introduce our two recent works on SNIa based on data-driven approach. The …

Variable selection for modeling the absolute magnitude at maximum of Type Ia supernovae

We discuss what is an appropriate set of explanatory variables in order to predict the absolute magnitude at the maximum of Type Ia supernovae. In order to have a good prediction, the error for future data, which is called the "generalization error," …
