Resource pressures, heavy workloads and improving service delivery are among drivers for policing to adopt machine learning algorithms to increase capacity and capability; but Research Fellow Hazel Sayer, machine learning specialist Dr Tamara Polajnar and Senior Research Fellow Dr Ruth Spence warn that key stakeholders need to be involved in determining the problem to be addressed, whether the algorithm is the right solution, and whether the force has the capacity to develop the technology and respond to its output.
