Consider the DBSCAN algorithm, where r is the radius and t the threshold. Assume that the threshold value is set to t $=1.$ Obtain the number of clusters that the DBSCAN algorithm identifies in the dataset shown in Figure $2$ for r $=0\mathrm{.}3,$ r $=1\mathrm{.}3$ and r$=2\mathrm{.}3.$

$-$ For r$=0\mathrm{.}3,$ the number of clusters is Answer $1$ Question $11$

$-$ For r$=1\mathrm{.}3,$ the number of clusters is Answer $2$ Question $11$

$-$ For r$=2\mathrm{.}3,$ the number of clusters is
