It addresses the aforementioned updating issue by converting the problem to that of minimizing several quadric functions iteratively, in which energies can be expressed in a simpler manner and their derivatives form a linear system.
At the core of this conceptualization, one may find the tension between dialectical dimensions, concrete/abstract and active/reflective, which is solved by mental operations of grasping experience and its transformation, by considering learning as a spiral quadric cycle where people learn through experience, which support the translation of experiences into concepts, allowing their application in new experiences: concrete experience, abstract conceptualization, reflective observation and active experimentation.
