Diverse Learners Requirements

• Diverse Learners
• Heterogeneous, Distributed and Autonomous Data
  Sources.
• Expensive and Complex Task.

3
Middleware

• Middleware is a layer of software, which exists
  between
• the network and software applications, to provide
  the
• connectivity between applications running on
  different systems.
• Examples of Object Oriented middleware
• Common Object Request Broker Architecture(CORBA),
  
• Microsofts Component Object (COM) and
• JAVA Remote Method Invocation (RMI).

Our Solution

• Employs new technologies to overcome existing
  limitations
• Distributed learning through middleware,
• XML-based data exchange and interaction,
• Agent-based interaction and communication, and
• Intelligent decision making supported by machine
  learning.
