Model-based reasoning involves using a working model and real-world observations to draw conclusions. It is important in artificial logical systems and scientific reasoning. Model building is time-consuming, but once established, it can be used for a wide range of applications. It can also be the basis of scientific thought, allowing researchers to draw conclusions based on observations and a working model. Developing models requires input from various sources and can be updated as new observations arrive.
Model-based reasoning is the use of a working model and the accompanying real-world observations to draw conclusions. It plays an important role in artificial logical systems and reasoning in the sciences. Model building is the time-consuming aspect of this approach, as you need to make the model as deep, complex, and detailed as possible to get the best results. Once a working model is established, it may also require periodic updates.
In an example of model-based reasoning, a company might develop a working neurological model of the human body. The model would normally include information about the network of connections present in the central and peripheral nervous systems. Data on symptoms of neurological problems could be integrated into the system, using observations to create a matrix of known information. A user could potentially interact with the model by inputting patient symptoms, such as slurred speech and unevenly dilated pupils, and would return a potential diagnosis, such as stroke.
Such systems can have a wide range of applications in the sciences. Artificial systems can allow researchers to explore and test hypotheses. Model-based reasoning can also be the backbone of a monitoring system that sends alerts based on inputs. Climate modeling, for example, allows computers to take information about current weather conditions and run it through a model to provide insight into budding tropical storms and other worrisome weather events. Automating some tasks can allow researchers to focus on other topics that require more complex reasoning.
The same concept can also be the basis of some forms of scientific thought. Researchers maintain working models of scientific concepts, such as how plate tectonics work, and make observations to strengthen the model and develop a compendium of supporting information. This allows them to draw conclusions about scientific events, based on what they know from the model and the observations they have made. For example, if researchers are monitoring a volcano, model-based reasoning may allow them to issue an evacuation warning if the volcano’s behavior is consistent with an impending eruption.
Developing models can take time, patience, and input from a variety of sources. The more data points you have, the more accurate and detailed your model-based reasoning can be. This can help modelers avoid potentially costly mistakes, such as failing to anticipate a problem that would have been apparent with more data. As observations arrive, they can be added to the body of knowledge, which can result in changes in the model. For example, an observation might show that a model-based rule is actually wrong or ignores a particular variable.
