Review: True or False

$2$ points possible $($graded$)$

Consider the classification decision rule

hat$(y)=$sign$(*(x))$

where $xin{R}^d$ represent input data and yin$\{1,-1\}$ is the corresponding predicted labels, and we have

omitted the bias$/$offset term for simplicity.

Given the model above, determine if the following statements are True or False.

The feature map $$ is function from $R^d$ to $R^d.$

Select an option $v$

If $(x)in{R}^D,$ then the classification parameter $$ is also a vector in $R^D.($Answer based on the model

as written.$)$
