pacmann.io © 2022 – Pacmann AI 18 Logistic Regression ● One of the go-to tool in classification ● Also , one of the Generalized Linear Model ● What it tries to predict, binary outcome, either success or failure , or something similar to it. ● For example, user churn
pacmann.io © 2022 – Pacmann AI 19 Logistic Regression : Likelihood ● So given the task we would like to find the likelihood / distribution family that is suitable ● First, should be discrete ● Second, modelling each result independently ● The answer is Bernoulli Distribution θ : probability of event occuring
pacmann.io © 2022 – Pacmann AI 20 Logistic Regression : Linear Model ● So of course we have predictor Xi ● hence our θi result from our linear model ● θ : probability of event occuring
