چکیده
c) (The advantage of the statistical formulation is that makes the assumptions explicit. We will now challenge some of these.) Assume that instead of a fixed variance σ we now have a variance that depends on the sample point, i.e. zi = f(xi, θ) + ǫi, (3) where ǫi ∼ N (0, σ i ). This means that our sample is independent but no longer identically distributed. It also means that we have different degrees of confidence in the different measurements (zi, xi). Redo b) under these conditions.

In the last homework, the DLT algorithm was used to find the homography which minimized an algebraic cost function. In this homework, we wish to find the homography H which minimizes the geometric cost function given by Equation 4.6 in the textbook (pg. 94) (1) where d() is Euclidean distance. Equation (1) can be rewritten as a nonlinear least squares problem with the form C(p) = X − F (p) 2 (2...

There seems to be a general consensus in the literature that doing homework is beneficial for students. Thus, the current challenge is to examine the process of doing homework to find which variables may help students to complete the homework assigned. To address this goal, a path analysis model was fit. The model hypothesized that the way students engage in homework is explained by the type of...

The difficulty of learning depends on the type of task involved. Remembering new terminology is relatively easy, while applying the ideas underlying design decisions shown by example to new problems posed as human tasks is relatively hard. In this short summary, we give you lists at several levels of difficulty of what we expect you to be able to do as a result of the last few weeks of studying...
