Reference: Pg (page number) in AI textbook
- Refer Pg 321 (Fig 10.1) -> Belief System: Object-oriented view in the universe which is opposite to AI beliefs.
- Ontology works really well with physical objects.Example: Physics (What is light? Is it physical object (its both wave & particle and in some case not both), sound -> Is wave not a object)
- Time as an object??? So when it comes to sound,time,air etc modeling it as an object is difficult. Example: Sound is auto-correlated.
- Time in terms of events works well. So refer Event Calculus at Pg 328.
- "All activities of the house, is based on the house itself, not the creation of its community"
- Modeling and Benefiits of modeling -> are both very different
- Limitation -> expressed as an object (including action). Representation like formal languages of Agents,etc.
- So the question is: "When you do what?"
- In Agile Artifacts -> Everything is goal-oriented. Its true for humans,cats,ants etc...then it should be true for the system we build too!
- Why??? -> Physical objects are regarded as generalized events -> Strange!!!
- Refer chart 10.1 -> it does not make sense why FOL (First Order Logic) falls apart; its misunderstanding how people process the information without appropriate data collecting & investigating.
- Example: people prefer analog clock than digital clock. As most people are based on abstraction (depends on grammar)
- A sentence is true only when its grammar (set of rules) is true/correct.
- Refer liquid events -> Pg 337 & fluent calculus -> Pg 333
- Fluent calculus: is used for restricted domain area -> cannot apply for generalized objects.
- Mental Events & Mental Objects: (Pg 341) is about the belief.
- Ability of agents (in wumpus world) works on a belief system. Read formal theory of beliefs on Pg 341.
- "Turning a proposition into an object is called reification" -> Example: Clock & Superman (Refer Pg 341)
- In AI -> Separate in your head -> the real world and the model.
- Refer Pg 342 -> Opaque -> using 2 approaches: one complicated and the other representing as strings. Example this._____ in Java (which does not have other reference system)
- Reasoning (Pg 349 -> 10.6) -> even refer Fig 10.9 on Pg 351
