Chapter 11: Managing Knowledge and Artificial Intelligence Flashcards
role of knowledge management systems, AI & ML, enterprise, knowledge work systems
Managing AI: Grand vision vs Realistic vision
- grand vision: computer hardware & software that are as “smart” as humans, so far this is not the case - at least holistically speaking
- realistic vision: systems take data inputs, process them & produce outputs, but on a complexity level that is far superior to human capabilities
Major types of AI
- expert systems
- machine learning
- neural networks & deep learning networks
- genetic algorithms
- natural language processing (LLMs)
- computer vision
- robotics
Expert systems
- capturing tacit knowledge in very specific & limited domain of human expertise, knowledge as set of rules
- performing limited tasks- discrete, highly structured DM
- knowledge base: set of hundreds or thousands of rules
- inference engine: Strategy used to search knowledge base, using forward chaining (data-driven technique towards a goal) or backward chaining (goal-driven technique from a goal towards origin to extract facts)
Machine learning
- Software that can identify patterns & relationships in very large data sets without programming, but significant human training
- pattern recognition
- requires experience through prior learnings (database)
- supervised learning turns into unsupervised learning
–> google searches, recommender systems
–> sustainability issue
Neural networks
- definition: algorithms loosely based on the processing patterns of the biological brain that can be trained to classify objects into known categories based on data inputs
- purpose: inding patterns and relationships in massive amounts of data
- functioning: “learn” patterns by searching for relationships, building models & correcting repeatedly
- data input: humans “train” network by feeding it data inputs for which outputs are known
- input layer –> hidden layer –> output layer
Genetic algorithms
- problem-solving methods that promote the evolution of solutions to specified problems using the model of living organism adapting to their environment (evolution)
- useful for finding optimal solution for specific problem by examining very large number of possible solutions (used in optimization problems)
Natural language processing
- understand & speak in natural language, read natural language & translate
- typically today based on machine learning, aided by very large databases of common phrases & sentences in a given language
- Google Translate, spam filtering systems, customer call center interactions, assistances (Siri, Alexa, Cortana, Google Assistant)
Computer vision systems
- digital image systems that create a digital map of an image (like a face, or a street sign)
- Facebook’s DeepFace, passport control, identifying people in crowds, autonomous vehicles, industrial machine (robot) vision
Robotics
- design, construction, and operation of machines that can substitute for humans in many factory, office & home applications (home vacuums)
- generally programmed to perform specific and detailed actions in limited domains
- Used in dangerous situations like bomb disposal
- Surgical robots are expanding their capabilities
Intelligent agents
- work without direct human intervention to carry out repetitive, predictable tasks (limited built-in or learned knowledge base) –> chatbots, agent-based modeling applications
What is hybrid intelligence & what is it used for? (NOT RELEVANT)
„ability to achieve complex goals by combining human and artificial intelligence, thereby reaching superior results to those each of them could have accomplished separately, and continuously improve by learning from each other“
- collectivity, superior results, continuous learning
- used when the result of joint work is better than the separate work
- most probable paradigm for division of human & machine labor, as it highlights complementary strenghts (contrary to collective intelligence)
Different types of intelligence (NOT RELEVANT)
- intelligence: „the ability to accomplish complex goals, learn, reason, and adaptively perform effective actions within an environment” –> acquire and apply knowledge
- collective intelligence: „groups of individuals acting collectively in ways that seem intelligent’‘
- artificial intelligence: ‘‘[…] systems that perform activities that we associate with human thinking, activities such as decision-making, problem solving, learning“
What is the Moravec paradox? (NOT RELEVANT)
It is comparatively easy to make coputers exhibit adult level performance on intelligence tests etc., but the skills of a 1-year old (perception, mobility, common sense) are difficult to emulate
What is the “human in the loop”? (NOT RELEVANT)
integration of a human workforce in the AI pipeline in order to train and validate models in a continuous way
Relevance of knowledge management systems in business
- fastest growing areas of software investment
- 37% U.S. labor force: knowledge and information workers
- 55% U.S. GDP from knowledge and information sectors
- Substantial part of a firm’s stock market value is related to intangible assets: knowledge, brands, reputations, and unique business processes
