Evaluation Comparison between PCE and DiCE

Metric	Method	Euclidean	Manhattan	Cosine
$d_{mean}$	DiCE	2.48	7.72	0.26
	PCE	1.24	2.80	0.17
$d_{R_{mean}}$	PCE/DiCE	0.54	0.42	0.79
${\text{\%}}_{closer}$	PCE<DiCE	0.62	0.62	0.42

^*The bold number shows the best performance. The smaller the distance metric, the better.
