What the specialist will work on

An existing AI is already deployed that aids this process. The CAID Transformation Programme will have 2 AI Classifiers to assess Indecent Images of Children (IIoC). The “1st AI Classifier”, and “The “2nd AI Classifier”.We seek a supplier to deliver a combined AI classifier harness to bring together the predictive outputs of 2 or more classifiers to produce better classification outcomes with significantly less burden on Police Officers.
