Losing data

[kbotello129]

Hi, I have an inquiry about the Keppler Mapper code. I am using

kmapper.KeplerMapper.map(
projected_data,
original_data,
cover=km.Cover(n_cubes=20, perc_overlap=0.15),
clusterer=sklearn.cluster.DBSCAN(eps=0.129),
)

to obtain my mapper. However, when I look the html file and check in the mapper summary the unique samples amount, I see a less amount of data than the original one. For example, My original data contains 1168 elements but the unique samples in the mapper summary are 859. I thought this was due to the outliers in the clusterer, but the amount of outliers is less than the amount of lost data. I really appreciate any help.
