Understanding

Understanding and knowledge are both words without unified definitions. Ludwig Wittgenstein looked past a definition of knowledge or understanding and looked at how the words were used in natural language, identifying relevant features in context. It has been suggested that knowledge alone has little value whereas knowing something in context is understanding, which has much higher relative value but it has also been suggested that a state short of knowledge can be termed understanding. Someone's understanding can come from perceived causes or non causal sources, suggesting knowledge being a pillar of where understanding comes from. We can have understanding while lacking corresponding knowledge and have knowledge while lacking the corresponding understanding. Even with knowledge, relevant distinctions or correct conclusion about similar cases may not be made, suggesting more information about the context would be required, which alludes to different degrees of understanding depending on the context. but, it has been argued that knowing how the cause might bring an effect is understanding. The relationships grasped help understanding, but the relationships are not always causal. So understanding could therefore be expressed by knowledge of dependencies. ==As a model==

Gregory Chaitin propounds a view that comprehension is a kind of data compression. In his 2006 essay "The Limits of Reason", he argues that understanding something means being able to figure out a simple set of rules that explains it. For example, we understand why day and night exist because we have a simple model—the rotation of the earth—that explains a tremendous amount of data—changes in brightness, temperature, and atmospheric composition of the earth. We have compressed a large amount of information by using a simple model that predicts it. Similarly, we understand the number 0.33333... by thinking of it as one-third. The first way of representing the number requires five concepts ("0", "decimal point", "3", "infinity", "infinity of 3"); but the second way can produce all the data of the first representation, but uses only three concepts ("1", "division", "3"). Chaitin argues that comprehension is this ability to compress data. This perspective on comprehension forms the foundation of some models of intelligent agents, as in Nello Cristianini's book "The Shortcut", where it is used to explain that machines can understand the world in fundamentally non-human ways. ==References==
