Figure 5.6: False negatives for Feature-based technique.<br />
The feature-based technique finds the exact query sequence in each dataset<br />
match. The results are accurate but are constrained by the fact that the binary<br />
sequence of the query and the data file should be exactly the same. That reduces the<br />
number of matches and results in large number of false negatives (see Fig 5.6). The<br />
remarkable thing about this technique is that it finds all the occurrences of the query<br />
in the data file and not just the best possible match. The number of false positives<br />
is very low (see Fig 5.7).<br />
