Suppose that for some linear regression problem (say, predicting housing prices as in the lecture), we have some training set, and for our training set we managed to find some θ0, θ1 such that J(θ0,θ1)=0. Which of the statements below must then be true? (Check all that apply.)
For this to be true, we must have y(i)=0 for every value of i=1,2,…,m.
这个答案为什么对？ J(θ0,θ1)=0 和 y(i)=0 for every value of i=1,2,…,m 我怎么觉得一点都扯不上关系啊
