WebYou have to get the partial derivative with respect θj. Remember that the hypothesis function here is equal to the sigmoid function which is a function of θ; in other words, we need to apply the chain rule. This is my approach: J(θ) = − 1 m m ∑ i = 1yilog(hθ(xi)) + (1 − yi)log(1 − hθ(xi)) WebMar 29, 2015 · 2 Answers. Sorted by: 1. I assume you can exchange partial derivatives, so that: ∂ ∂ θ ∂ z ∂ x = ∂ ∂ x ∂ z ∂ θ. Then you can use your answer form part (i) to plug into ∂ z ∂ θ, and take the partial of that with respect to x.
