Abstract:
|
During the past several years there has been a serious effort by the community of forensic scientists to move away from subjective conclusions based on the findings from a forensic examination of evidence, by trained and experienced forensic examiners, to a more logical, probabilistic framework for quantifying the weight of such evidence using likelihoods, likelihood ratios, or other appropriate "objective" measures. This talk will give a brief explanation of competing approaches, discuss their pros and cons, and illustrate them using specific application areas such as pattern evidence (fingerprints, shoe-prints, etc.) and trace evidence.
