Web24 okt. 2024 · h (x) gives P (y=1 x; θ), not 1 - P (y=1 x; θ) Our estimate for P (y = 0 x; θ) is 0.8. Since we must have P (y=0 x;θ) = 1 - P (y=1 x; θ), the former is 1 - 0.2 = 0.8. Our estimate for P (y = 1 x; θ) is 0.2. h (x) is precisely P (y=1 x; θ), so each is 0.2. Our estimate for P (y = 0 x; θ) is 0.2. h (x) is P (y=1 x; θ), not P (y=0 x; θ)
WebInstead, our cost function for logistic regression looks like: When y = 1, we get the following plot for : Similarly, when y = 0, we get the following plot for : If our correct answer 'y' is 0, then the cost function will be 0 if our hypothesis function also outputs 0. If our hypothesis approaches 1, then the cost function will approach infinity. Web23 nov. 2016 · Linear regression via gradient descent is conceptually a simple algorithm.
