The blackboard model defines three main components:blackboard - a structured global memory containing objects from the solution space.knowledge sources - specialized modules with their own representation.control component - selects, configures and executes modules.
The Blackboard arrchitectural pattern is useful for problems for which no deterministic soluion strategies are known. In Blackboard several specialized subsystems assemble their knowledge to build a possibly partial or approximate solution.
A blackboard system is an artificial intelligence approach based on the blackboard architectural model, where a common knowledge base, the "blackboard", is iteratively updated by a diverse group of specialist knowledge sources, starting with a problem specification and ending with a solution.
A blackboard system consists of three components ( Figure 1 ) : Blackboard ( BB ), • Knowledge sources ( KSs), and • Control unit.
“Data-Oriented design shifts the perspective of programming from objects to the data itself: The type of the data, how it is laid out in memory, and how it will be read and processed in the game.” An example of a DOP call sequence.Mar 20, 2018
Q 6 - Which of the following is correct about Behavioral design patterns. A - These design patterns are specifically concerned with communication between objects. B - These design patterns provide a way to create objects while hiding the creation logic, rather than instantiating objects directly using new opreator.
The Pipe and Filter is an architectural pattern for stream processing. It consists of one or more components called filters. These filters will transform or filter data and then pass it on via connectors called pipes.
A repository architecture consists of a central data structure (often a database) and a collection of independent components which operate on the central data structure Examples of repository architectures include blackboard architectures, where a blackboard serves as communication centre for a collection of knowledge ...
Most layered architectures consist of four standard layers: presentation, business, persistence, and database. These four layers could vary for complex applications.May 26, 2019
1. An artificial intelligence application based on and analogous to a group of experts seated in a room with a large blackboard working as a team to solve a common problem.
Architectures must have both form and function and it is a good test of an architecture to measure its elegance. An architecture that is well designed will tend to be elegant and have a simplicity of form that will be obvious to those that take the time study it.
Advantages of Blackboard Architecture Style Blackboard architecture style provides concurrency which allows knowledge sources to work in parallel. This architecture supports experimentation for hypotheses and reusability of knowledge source components.
