% ANY LINE BEGINNING "%" IS A COMMENT. YOU CAN UNCOMMENT THE BELOW
% TEXT AND FILL IN YOUR OWN.
% \begin{solution}
% Hal has taken all of these classes! (Some of them more years ago
% than he would really like to admit.)
% \end{solution}
\i List a few (research/CS/math/whatever) topics that interest you.
% \begin{solution}
% Hal is interested in language, machine learning and recommender systems!
% \end{solution}
\i How would you rate your programming skills (1-10, 10 best)? How would you rate your math skills?
% \begin{solution}
% Programming: 8
%
% Math: 10
% \end{solution}
\i What are your goals in this class?
% \begin{solution}
% To teach you all about machine learning and have fun doing so!
% \end{solution}
\i I told you what irks me. What irks you?
% \begin{solution}
% You already know!
% \end{solution}
\i Please be sure that you have subscribed to the class mailing list or RSS feed.

\section{Additional Exercises}
The following are true/false questions. You don't need to answer the
questions. Just tell us which ones you can't answer confidently in
less than one minute. (You won't be graded on this.) If you can't
answer at least $6$, you should probably spend some extra time outside
of class beefing up on elementary math.
\bee
\i $\log x + \log y = \log (xy)$
\i $\log [ab^c] = \log a + (\log b) (\log c)$
\i $\ddx [5x^2 + 3x] = 10x + 3$
\i $\ddx \log x = - \frac 1 x$
\i $p(a \| b) = p(a,b) / p(b)$
\i $p(x \| y,z) = p(x \| y) p(x \| z)$
\i $\norm{\al \vec u + \vec v}^2 = \al^2 \norm{\vec u}^2 + \norm{\vec v}^2$, where $\norm{\cdot}$ denotes Euclidean norm, $\al$ is a scalar and $\vec u$ and $\vec v$ are vectors
\i $\ab{\vec u\T\vec v} \geq \norm{\vec u} \times \norm{\vec v}$, where $\ab{\cdot}$ denotes absolute value and $\vec u\T\vec v$ is the dot product of $\vec u$ and $\vec v$
\i $\int_{-\infty}^{\infty} \ud x \exp[-(\pi/2) x^2] = \sqrt{2}$
