Algorithm 1. Single example generator.
1	$S$ ← 32 random identities from 1 random database
2	while$\mathrm{size} \mathrm{of} S$ is less than 32:
3	db ← random database
4	$k$ ← random identity from db
5	if$k \mathrm{is} \mathrm{not} \mathrm{in} S$:
6	$\mathrm{add} \mathrm{identity} \mathrm{to} S$
7	$q\leftarrow \mathrm{random} \mathrm{identity} \mathrm{from} S$
8	$J$ ← empty set
9	$\mathbf{for} \mathrm{each} k \mathrm{in} S$:
10	$\mathbf{if} k \mathrm{is} \mathrm{equal} q$:
11	$G_k$$, G_q$ ← 2 random ECG segments without overlapped
12	else:
13	$G_k$ ← random ECG segment
14	$\mathrm{add} G_k \mathrm{to} J$
15	$\mathrm{filter} J \mathrm{and} G_q$
16	$\mathrm{standardize} J \mathrm{and} G_q$
