What is AI in science?
In the other hand, AI, is a general term which cover not just Expert Systems, but also Knowledge Representation, Planning and Machine Learning techniques which use a lot of probabilities calculations.
What is subsymbolic memory?
Subsymbolic means the data flowing around the system is only part of a symbol. For example, in neural networks, a memory is stored as the weight values of thousands of connections between artificial neurones. The advantage of this approach is robustness in the face of noisy input (basically, the real world).
What does symbolic mean in a sentence?
Symbolic means information is stored and transferred in entities that are full symbols for real things. For example, a natural language system may store the noun "finger" in full, with associated data and links to other entities, such as "has_a ("fingernail")".
What is supervised learning algorithm?
A "Supervised Learning" algorithm would determine, based on all the data available, mimic the end-behavior of the expert. This works well in many situations, since, algorithms that are efficient for machines may not be the most efficient for humans, and machines are more used to handling lots of different dimensions.
What is an expert system?
In an Expert System, the full knowledge of the expert acquired is digitized, and is used in the decision making. An expert specifies all steps he took to make the decision, the basis for doing the same, and how to handle exceptions. A pure/rigid system would try to follow exact rules from the expert.
What is a child node?
Child nodes may represent further tests or they may be leaf nodes. A leaf node represents a decision, typically a specific action to take given the facts corresponding to the test values. Decision trees are static and inert. They can be documents or computer-based.
What is leaf node?
A leaf node represents a decision, typically a spe. Continue Reading. A decision tree is a type of directed graph consisting of nodes and branches (aka arcs or links). All of the nodes except the lowest layer (aka terminal or “leaf” nodes) represent tests on some decision condition or factor (e.g.
