Hi,

1. In page 2 - If we assume that each sample is a scalar, shouldn't the linear relation assumption be with x and a as scalars (rather than vectors)?

2. The inequality $n \leq d$ at the end of page 5 - shouldn't it be a strict inequality?

3. In the case in page 6 where $v_{i}=v_{j}$:

$\space$ a. Are we putting weight of 0 to j in the case we are putting weight w on i?

$\space$ b. Why are we limiting alpha to be in (0,1)?

4. In page 6, before 10.5 - What is exact non-singularity and won't we have it?

5. Equation 10.9 in page 7 - Shouldn't there be $\lambda \|\mathbf{a}\|^{2}$ at the beginning of the equation?

Thank you very much
