The hierarchical agglomerative clustering algorithm is tocluster data from bottom to up. Here is the pseudo-code for it.Please implement hierarchical agglomerative clustering algorithm on2‐dimensional numerical data by C++, which should be fairly easy toderive from this.
SIMPLEHAC(d1, . . . , dN)
for o ← 1 to N
for p ← 1 to N
C[o][p] ← SIM(do, dp)
end
I[o] ← 1 (keeps track of active clusters)
end
A ← [] (assembles clustering as a sequence of merges)
for k ← 1 to N − 1
<i,m> ← argmax{:i≠m∧I[i]=1∧I[m]=1} C[i][m]
A.APPEND(<i,m>) (store merge)
for j ← 1 to N
C[i][j] ← SIM(i,m, j)
C[j][i] ← SIM(i,m, j)
End
I[m] ← 0 (deactivate cluster)
end
return
