Cluster evaluation methods
WebFirstly, based on the traditional FCM clustering algorithm, the entropy method is used to introduce the PFS index and the Vp index in a weighted form to achieve a comprehensive evaluation of the clustering effect. WebMethods & Procedures: A convergent interactive mixed-methods sustainability evaluation was conducted on two previously delivered implementation interventions (AAIMS). The AAIMS interventions were targeted at improving either written aphasia-friendly information provision (Intervention A) or collaborative goal-setting (Intervention B).
