Let’s start with the simpler problem: regression. The entire process is three-fold: 1. Calculate the first- and second-order derivatives of the objective function 2. Implement two functions; One returns the derivatives and the other returns the loss itself 3. Specify the defined functions in lgb.train() See more Binary classification is more difficult than regression. First, you should be noted that the model outputs the logit zzz rather than the probability y=sigmoid(z)=1/(1+e−z)y=\mathrm{sigmoid}(z) = 1/(1+e^{ … See more WebMar 16, 2024 · Cambiar a Navegación Principal.
