WebWith logistic regression, we were in the binary classification setting, so the labels were y ( i) ∈ {0, 1}. Our hypothesis took the form: hθ(x) = 1 1 + exp( − θ⊤x), and the model parameters θ were trained to minimize the cost function. J(θ) = − [ m ∑ i = 1y ( i) loghθ(x ( i)) + (1 − y ( i))log(1 − hθ(x ( i)))] Web1 jul. 2016 · 2 Answers Sorted by: 2 It is the same way that we graph the linear equations. Let us assume h (x) as y and θ as some constant and x as x. So we basically have a …

WebWhat is cost function: The cost function “J( θ 0,θ 1)” is used to measure how good a fit (measure the accuracy of hypothesis function) a line is to the data. If the line is a good fit, then your predictions will be far better. The idea is to minimize the value of J by calculating it from given values of θ 0 and θ 1. WebWith logistic regression, we were in the binary classification setting, so the labels were y ( i) ∈ {0, 1}.
