Instance based learner
NettetThe process of selecting these patients (or more generally instances) based upon the data we have collected so far is called active learning. Scenarios. In active learning, there are typically three scenarios or settings in which the learner will query the labels of instances. The three main scenarios that have been considered in the literature ... In machine learning, instance-based learning (sometimes called memory-based learning ) is a family of learning algorithms that, instead of performing explicit generalization, compare new problem instances with instances seen in training, which have been stored in memory. Because computation is postponed until a new instance is observed, these algorithms are sometimes referred to as "lazy."

Experiential Learning: this is not controlled by teachers and there are no predetermined objectives. What is learned is determined by context, learners¶ PRWLYDWLRQs, the others with whom they come in contact, discoveries made, etc.
