In an unsupervised learning application, there is no outcome variable to predict; rather, the goal is to use the variable values to identify relationships between observations. Without an explicit outcome variable, there is no definite measure of accuracy. Instead, qualitative assessments, such as how well the results match expert judgment, are used to assess unsupervised learning methods.
