Binary observations
WebNov 29, 2024 · Image by author, using image files from flaticon.com. To produce a binary response, classifiers output a real-valued score that is thresholded. For example, logistic regression outputs a probability (a value between 0.0 and 1.0); and observations with a score equal to or higher than 0.5 produce a positive binary output (many other models … WebJan 26, 2024 · By definition, an RBM with binary visible units can only model binary observations. So in the case of MNIST with integer pixel values in [0, 255], some sort of thresholding can be done to binarize the input. Or, like you suggested, rescale the pixel values to real numbers and use Gaussian visible units to model them.

WebDec 19, 2024 · There isn't really a minimum number of observations. Essentially the more observations you have the more the parameters of your model are constrained by the data, and the more confident the model becomes. How many observations you need depends on the nature of the problem and how confident you need to be in your model. flaming bicycleWebApr 10, 2024 · We demonstrate that combining spectroscopic and interferometric observations of binary stars provides extremely precise and accurate dynamical masses and orbital parallaxes.
