演講者:張系國 教授 Slow Intelligence Systems- A New Approach for Component-based Software Engineering
Prof. S. K. Chang演講者—張系國 • 知識系統學院創辦人 (Founder, Knowledge Systems Institute www.ksi.edu)。 • 旅美教授,任教於匹茲堡大學(Professor, University of Pittsburgh www.pitt.edu)。 • 張教授除了是電腦科學學者外,亦從事小說創作 (Writer and novelist)。 • www.cs.pitt.edu/~chang
Outline • IT does not matter! • What is the matter? • What is “W-H-A-T”? • Enabling Technologies • Slow Intelligence Systems • SIS Applications • Q & A
In 2003, Nicholas Carr wrote an interesting article in Harvard Business Review. Its title is: “IT Doesn’t Matter” • He argued that information technology is no longer the decisive factor in business. This article caused quite a stir. A lot of IT gurus, including Bill Gates, argued against Carr’s view. • If IT does not matter, WHAT is the matter?
What is IT? IT=? Information Technology
What is the matter? What is the matter? Let us return to the future.…
W T H What is “W-H-A-T”? Warfare? Training Weisure Agriculture A Amusement? Healthcare
W-H-A-T is in common? • Connected • Multiple sourced • Knowledge-based • Personalized • Hybrid
Smarter Planet • We are all now connected - economically, technically and socially. Our planet is becoming smarter via integration of information scattered in many different data sources: from the sensors, on the web, in our personal devices, in documents and in databases, or hidden within application programs. Often we need to get information from several of these sources to complete a task. Examples include healthcare, science, the business world and our personal lives. (Quoted from Josephine M. Cheng, IBM Fellow and Vice President of IBM Research)
Hybrid Intelligence • While processor speed and storage capacity have grown remarkably, the geometric growth in user communities, online computer usage, and the availability of data is in some ways is even more remarkable. Hybrid Intelligence offers great opportunities we have to harness this data availability to build systems of immense potential. While today s large scale systems are evolutionarily based on the distributed computing technologies envisioned in the 70 s and 80 s, sheer scaling has led to many unanticipated challenges. (quoted from Alfred Z. Spector, Vice President, Research and Special Initiatives, Google, USA)

Slow Intelligence Systems • Slow Intelligence Systems are general-purpose systems characterized by being able to improve performance over time. • A slow intelligence system is • a system that (i) solves • problems by trying different • solutions, (ii) is context- • aware to adapt to different • situations and to propagate • knowledge, and (iii) may • not perform well in the • short run but continuously • learns to improve its • performance over time.

Slow Intelligence Systems • A SIS continuously learns, searches for new solutions and propagates and shares its experience with other peers. • From the structural point of view, a SIS is a system with multiple decision cycles such that actions of slow decision cycle(s) may override actions of quick decision cycle(s), resulting in poorer performance in the short run but better performance in the long-run.
Mathematical Formulation of BBB • For the two-decision-cycle SIS, the basic building block BBB can be formulated methematically as:if timing-control(t) == 'slow' then y(t)solution = gconcentrate (geliminate (gadapt (genumerate (x(t) problem)))) else if timing-control(t) == 'quick' then y(t) solution = fconcentrate (feliminate (fadapt (fenumerate (x(t) problem))))
OUR RESEARCH AGENDA • A Framework to study Natural Slow Intelligence Systems • A Test bed to develop Artificial Slow Intelligence Systems • Component based • Multiple decision cycles • Evolutionary ontology • Learning rules • Visualization
SIS Application to Product Configuration Productionof personalized or custom-tailored goods or services to meet consumers' diverse and changing needs “Like its driver each Toyota Echo is unique!”
Ontological Transformations User Layer Instance Layer Functionality Layer Components Layer
Sequence of Ontological Transformations • In this way, the configuration problem CP can be formulated in its general formulation as the composition of ontological transformations: FC(FEL(FA(FEN(UR, UP)))). • Similar to a SIS, the proposed Configurator can follow a slow and a fast process of solution inference. So, the previous formulation can be defined as the slow process, while the fast process can be defined as a simplified sequence of ontological transformations: FC(FEN(UR, UP)).
A Scenario • A customer would like to buy a Personal Computer in order to play videogames and surf on the internet. • He knows that he needs an operating system, a web browser and an antivirus package. • In particular, the user prefers a Microsoft Windows operating system. He lives in the United States and prefers to have a desktop. He also prefers low cost components.
Experimental Results • A set of common computer configurations based on usage scenarios were identified for evaluation • The allowed configurations for the personal computer are so named: • Play_Videogame (PV) • Web_Surfing (WS) • Online_Gaming (OG) • Multimedia_Design (MD) • Computer_Aided_Design (CAD) • Music (MUS) • Word_Processing (WP) • School_Work - Web_Surfing and Word_Processing (SW)

Discussion • There are a large number of intelligent systems, quasi-intelligent systems and semi-intelligent systems that are "slow". Distributed intelligence systems, multiple agents systems and emergency management systems are mostly slow intelligence systems that exhibit the characteristics of multiple decision cycles.
Discussion (continued) • Since time is relative, "slow" intelligence systems for some can also be "fast" for others. • A slow intelligence system can evolve into a fast intelligence system. • A SIS differs from expert systems in that the learning is not always obvious.
Conclusions • In the age of micro-profit economy, Information Technology to acquire, communicate and apply knowledge to reduce cost and improve efficiency will still be a decisive factor. • IT is KNOWLEDGE TECHNOLOGY. • EVERY INDUSTRY is IT INDUSTRY.
