WebMore specifically, consider a binary regression model which can be used to classify observations into two possible classes (often simply labelled and ). The output of the model for a given observation, given a vector of input features , can be interpreted as a probability, which serves as the basis for classifying the observation. WebDanilov, Vladimir M. Binary stars are present in all stellar systems, yet their role is far from being fully understood. We investigate the effect of unresolved binaries in the derivation of open clusters’ mass by star counts. We start from the luminosity functions of five open clusters: IC 2714, NGC 1912, NGC 2099, NGC 6834, and NGC 7142.
