WebStep 1: Plot at point at the y-intercept Step 2: Write the gradient in the form m = rise/run Step 3: Starting from the y-intercept, move up the number of units suggested by the rise (or move down if the number is negative) Step 4: Move the right the number of units suggested by the run and plot the second point. WebThen there is exactly one vector that minimizes J ( p) and this vector is the solution of the linear equation, (57) A p = b. The proof of this statement is straightforward. Let us compute the gradient of J: ∇ J = A p − b. To get the above expression we have used A = A T. The gradient of J is therefore equal to zero if A p = b.
