Selecting the Best Picker: Neo K Sigma


Experiments were conducted for 3 different types of pickers: Old Picker, the HMM Picker and New K-Sigma Picker.

The HMM Picker and New Picker showed multitudes of reduction in false positive. However, HMM suffered rise in false negatives as well. The table below makes this fact more clear:


Old Picker
HMM Picker
Neo Picker
True Positives
1,084
991
1,070
False Negatives
116
209
130
False Positives
72,874
39,280
1,808

Considering this data, and considering the computation cost, New K-Sigma picker appeared to be best experiment for the remainder of the project.
