fingermarks Bayesian Networks
Description
Using case specific experiments to evaluate fingermarks on knives given activity level propositions.
Format
A discrete Bayesian network for the evaluation of fingermarks given activity level propositions. The probabilities were given within the referenced paper. The vertices are:
- C1
Propositions (Hp, Hd);
- C2
Suspect stabbed the victime with the knife (True, False);
- C3
Suspect cut food with the knife (True, False);
- C4
Marks on handle - stabbing (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
- C5
Marks on back - stabbing (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
- C6
Marks on blade - stabbing (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
- C7
Marks on handle - cutting (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
- C8
Marks on back - cutting (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
- C9
Marks on blade - cutting (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
- C10
Findings - Marks on handle (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
- C11
Findings - Marks on blade (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
- C12
Findings - Marks on back (P, F, P_F, P_T, F_T, P_F_T, Undetermined, None);
