- 1. A Machine Learning Approach to Programming
- 2. Agenda Overview of current methodologies. Disadvantages of current methodologies. MLAP: What, Why, How? MLAP: An example. MLAP: Design MLAP: Advantages/Disadvantages Scope Conclusion
- 3. Overview of software methodologies SSAD: Here programming is procedural. The mapping between a real life object n its representation in a program is ambiguous. OOAD: Here real life objects are mapped as classes in a program. Each class consists of attributes n methods.
- 4. Disadvantages of other Methodologies Testing n error fixing takes a very long time. Enhancements are based on user feedback n usage. Collecting this information is a cumbersome process. Usability issues are not given enough importance because of lack of information. Optimization is difficult because of inadequate information.
- 5. What is MLAP? In MLAP, a program encodes information about itself i.e. it is aware of its own design. It is a natural consequence of the Object Oriented Methodology wherein real-life objects are represented as classes. In MLAP, each class is also aware of its construction n purpose. This is an effort to take programming to a higher level wherein the program can fix its errors on its own n provide a better user experience i.e. minor defects r fixed by the program n the program helps a user make the best use of the application n runs based on the user’s preferences.
- 6. MLAP- An Example class A { private: attribute1; attribute2; classinfo; //encodes functionality details //of class A public: method1(); method2(); getclassinfo(); //retrieves details of class A };
- 7. MLAP- An Example Each class contains information about itself which is encoded as an attribute. This information can be stored in predicates to record functionality.
- 8. Design EBL Engine Subsystem Subsystem Subsystem Knowledge Base Expert System for Error Processing n Optimization Application
- 9. Design EBL Engine: This will learn how it is used in the execution environment. The engine uses Explanation Based Learning. Domain theory will be specific to the application. Knowledge Base: This will store domain theory n any rules that the EBL generates. ES for Error Processing n Optimization: This can be added for real-time error processing n fixing.
- 10. Advantages Error fixing: Recording error info (steps traversed at the time of the error, point in code where error took place), real-time error processing will reduce time required to fix defects immensely. Functionality/design enhancements: Recording code coverage n class usage for optimization n accurate error information will speed up development of new releases.
- 11. Advantages Usability: Various aspects of usage will be recorded by different users for usability studies. Customization based on user preferences: UI preferences ,order of functions, batch processing based on user preferences n providing help whenever a user needs it will provide for a better user experience.
- 12. Disadvantages Higher memory usage. An enhancement to a Basic implementation. Higher costs. Performance overhead due to additional functions.
- 13. Scope Project is still in its implementation stage. The idea is to build an EBL engine with a knowledge base to support the application. An expert system shell can be developed at a later stage for error processing.
- 14. Conclusion In MLAP, a program encodes information about itself n can enhance its own performance. It can improve n speed up the process of error fixing. It is aware of its functionality n design and works towards its enhancement. It can provide a better user experience.
