Survival analysis results with different feature encoding algorithms

Method	Evaluation I		Evaluation II
	p-value	c-index	p-value	c-index
Cellular voting	0.0290	0.5103	0.0320	0.5739
Aggregate statistic [6, 7]	0.0083	0.6798	0.2200	0.6750
BoW encoding	0.0290	0.6591	0.0045	0.6770
LLC-sum encoding	0.0110	0.6874	0.0260	0.6751
LLC-max encoding	0.0031	0.6911	0.0470	0.6770

Note that lower p-values are better, whereas higher c-index values are better
