Only save the cluster assignment
We'll run the same command again for the
SimpleKMeans
and
Cobweb
clustering algo‐
rithms. We now have three files with cluster assignments. Let's create a t-SNE map‐
ping in order to visualize the cluster assignments:
$
< wine-both-scaled.csv csvcut -C quality,type | body tapkee --method t-sne |
>
header -r x,y > wine-both-xy.csv
Next, the cluster assignments are combined with the t-SNE mapping using
paste
and
a scatter plot is created using
Rio-scatter
(see Figures
9-5
,
9-6
, and
9-7
):
$
parallel -j1
"paste -d, wine-both-xy.csv wine-both-cluster-{}.csv | "
\
>
"Rio-scatter x y cluster | display"
