WebJul 18, 2024 · Logistic regression returns a probability. You can use the returned probability "as is" (for example, the probability that the user will click on this ad is 0.00023) or convert the returned probability to a binary value (for example, this email is spam). ... (also called the decision threshold). A value above that threshold indicates "spam"; a ... WebApr 8, 2024 · By definition, the decision boundary is a set of (x1, x2) such that the probability is even between the two classes. Mathematically, they are the solutions to: b + w1*x1 + w2*x2 + w11*x1^2 + w12*x1*x2 + w22x2^2 = 0. If we fix x1, then this is a quadratic equation of x2, which we can solve analytically. The following function does this job.
