Q

what are the 3 ways humans think?

A
  • introspection (observing thoughts + emotions in action).

Q

how is the cognitive modelling approach used?

A

once it has a precise theory of the mind it becomes possible to express the theory as a computer program.

Q

what does cognitive science do in relation to the cognitive modelling approach?

A

it brings together computer models from ai + experimental techniques from psych to construct precise + testable theories of the human mind.

Q

what is meant by the “law of thought” approach?

A

it entails the ideas of thinking rationally through logic and applying that into ai algorithms.
describes how the human mind should work laying down the foundation for the field of logic.

Q

what does it mean by codifying right thinking?

A

logic provides structured patterns for reasoning, ensuring that info is arranged in a way that others can follow - creating rules that govern rational thought.

Q

what are the limitations of logic?

A

it always assumed that knowledge is 100% certain (in reality it deals with uncertainty).

Q

how can we reduce these limitations of logic in the “law of thought” approach?

A

the use of probability in ai can help fill this gap by allowing reasoning with uncertainty, modern ai uses probabilistic models instead of strict logical rules.

Q

is thinking rationally the only way to create intelligent behaviour?

A

no, rational thinking is only 1 way to create intelligent behaviour + needs other approaches to create enough to be successful.

Q

16
Q

what is meant by an agent in ai?

A

anything that percieves its environment + takes action to achieve a goal. this could be a self driving car or chatbot.

17
Q

what is meant by a rational agent?

A

one that makes decisions to maximise its chances of success.

18
Q

what are the key characteristics of a rational agent?

A
  1. autonomy (operates independantly without human intervention).
  2. perception (observes environment through sensors).
  3. goal oriented (makes decisions that align with a defined objective).
  4. adaptability (can learn + adjust its actions based on new info).
  5. persistence (can work over a long period of time without consistent monitoring).
19
Q

what are the different ways in which we can think rationally?

A
  • deduce that a given action is best + then act on that conclusion (not always correct).
  • ways that can’t be said to involve inference (eg recoiling from a hot stove is a reflex action that is used more successfully than a slower action taken after careful consideration).
20
Q

what is the conclusion made of the ways of thinking rationally?

A

that thinking rational is one way to act rational.

21
Q

what are the advantages of the rational agent approach?

A
  • can be mathematically defined + well tested.
  • recognises there are many possible strategies for making intelligent decisions.
  • easier to analyse scientifically as it is based on mathematical models of decision making.
22
Q

what are the disciplines that contributed ideas, viewpoints + techniques of ai?

A
  • philosophy
  • maths
  • economics
  • neuroscience
  • psychology
  • linguistics
  • computer engineering
  • cybernetics + control theory
23
Q

is ai moving from automation to augmentation?

A

the relationship between humans + machines is shifting to a more collaborative + augmentative one. instead of viewing ai as a threat that replaces human workers it should be seen as a tool that enhances human abilities.

24
Q

what is meant by opacity?

A

ai is opaque meaning it is not always possible to expkain its outcomes.
the opposite of transparency, referring to when info is hidden or difficult to understand.

25
Q

what are the reasons for ai being opaque?

A
  • complexity use of the algorithmic code
  • the use of multiple algorithmic components which are not all know or under the control of the designers.
  • intrinsic characteristics of learning algorithms that redefine parameters + relationships with each additional data point which makes it hard to explain, algorithms have to be tweaked to make their results understandable.
26
Q

how does algorithmic opacity affect value creation?

A

if ai is not explainable it is impossible to determine the value it generates for orgs.

27
Q

what is meant by explainability paradox?

A

it refers to the challenges in ai where making a model becomes more + accurate makes it less interpret-able so looks at the needs for human understandable explanations of their decisions + behaviours.

28
Q

how does this create dilemmas for designers and users of ai?

A

they need to balance the need for accuracy + performance with the need for transparency + accountability.
it can be difficult to understand + interpret, even for experts, which can raise concerns about their reliability, fairness

29
Q

what is a benefit for prioritising complexity + accuracy of ai models?

A

highly complex ai models such as deep neural networks can achieve impressive levels of accuracy in tasks such as image recognition or natural language processing.

30
Q

can you discuss an example where privacy issues arose from prioritising complexity + accuracy in ai?

A

NHS + Deepmind partnership
- wanted to help detect kidney failure in patients however:
- data was shared without proper consent from patients which included sensitive info.
- the nhs did not inform the patients on how their data would be used.
- deepmind initially claimed the data would not be shared with google however in 2018, google took it over. this caused fears about the commercial use of data.

31
Q

how can an org assess the value creation of ai?

A

hard to determine ai’s true value for an org due to its opacity + rigidity.
ai algorithms need to be deeply analysed to see how it functions, without this it can lead to misinterpretations of its effectiveness.
doesn’t adapt to real world unpredictable conditions + forces the environment to fit into pre-defined logic.

32
Q

what is meant by generative ai?

A

ai models that generate new content based on learned patterns from existing data.
they don’t just recognise patterns, they produce creative outputs.

33
Q

what are some examples of generative ai?

A
  • text generation (chatgpt).
  • image generation
  • music generation
  • video + animation
  • code generation
34
Q

how does gen ai work?

A

its based on deep learning + neural networks.
they are trained on huge datasets + use statistical probabilities to generate new, coherent content.

35
Q

what do the key architectures of gen ai include?

A
  • generative adversarial networks: two ai models compete against each other, one generates data and one evaluates it.
  • transformers: these use massive datasets to generate human-like texts + responses.
36
Q

what are the challenges + ethical concerns of gen ai?

A
  • bias + ethical concerns: can generate biased or harmful content based on flawed training data.
  • copyright: who owns it?
  • misinfo + deepfakes: it can create realistic fake videos + news, leading to misinfo.
    lack of explainability: gen models are black boxes, making it difficult to understand how they make decisions.
37
Q

what is an example of the concerns + challenges of gen ai?

A

ai-generated deepfake videos can be used for both entertainment + fraud, raising concerns about digital trust.
