Supervised learning
labeled data, used for grouping, ex. spam filters
Unsupervised learning
unlabeled data, used for pattern recognition, ex. banking data
Reinforcement learning
maximizing rewards, ex. autonomous vehicles
Semi supervised learning
mix of labeled and unlabeled data
Data lineage
data origin, how its transformed, where it moves over time. ensures AI integrity and representative/accurate data.
Components of AI definition
technology, autonomy, human involvement, output
OECD Framework
purpose: to classify AI systems and examine risks
1) People & Planet, 2) Economic Context, 3) Data & Input, 4) AI Model, 5) Tasks & Outputs
AI use cases
recognition
event detection
forecasting
personalization
interaction support
goal driven optimization
recommendation
Dartmouth conference
1956 - formalized AI into academic field, where it was decided that human intelligence could be mimicked artificially with enough description, term “AI” created
1st AI summer (mid 1950s to mid 1970s)
immediately after Dartmouth conference, creation of LISP (1st AI programming language, John McCarthy) and ELIZA (1st NLP, Joseph Weizenbaum)
1st AI winter (mid 1970s to mid 1980s)
period of skepticism, funding cuts
2nd AI summer (mid 1980s - late 1980s)
rise of expert systems, increased computing capabilities, AI powered computers by Japanese gov (5th Gen Computer Systems)
2nd AI winter (late 1980s - late 1990s)
decreased interest due to cost of expert systems, end of Cold War
AI renaissance (late 1990s - 2011)
era of big data, IBM’s Deep Blue beats world chess champion, emergence of Internet
AI boom (2011 - present)
advancements in deep learning
Weak/narrow AI
perform narrow set of related tasks at high level of proficiency
Strong AI
strong generalization capabilities, closely mimic human intelligence, AGI
ASI
outperforming humans
Broad AI
capable of performing broad set of tasks, relies of group of AI systems (ex. Autonomous vehicles)
Robotics processing automation (RPA)
software robots that automate repetitive tasks
Expert systems components
knowledge base, inference engine, user interface
Implicit bias
discrimination/prejudice towards particular person or group
Sampling bias
data skews towards a subset
Temporal bias
model works now, may not work later
Group harms
mass surveillance, restriction of freedom of assembly/protest, deepening of inequities, harm to democratic process, spread of deepfakes, LAWS
Individual harms
civil liberties, rights, safety, economic opportunity
Economic risk
discriminatory hiring, loss of jobs
Organizational harms
negative brand impact, ESG ratings, share price drop, investors flight, campaigners
Pros of risk management framework
ensure requirements are met, auditability, accountability
OECD AI Principles
Inclusive growth, sustainable development, wellbeing
Human centered values and fairness
Transparency and explainability
Robustness, safety, and security
Accountability
