Task 1 Flashcards
What is meant by cognitive science ?
- Explains how the mind carries out task via gathering info from cognitive psychology, artificial intelligence, informatics, neurobiology, and philosophy
- study how the How the mind makes makes process based on neuronal system
What is the core of cognitive science ?
- computational-representational understanding of Mind (CRUM)
- Thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structure
What is meant by cognitive modeling?
- Translating psychological theory into a computer programm (simulating human problem-solving and mental processing)
What are the 3 steps of cognitive modeling ?
- computational lvl
- The representational lvl (How do we get to the goal in terms of steps)
- The physcial lvl (How can we implement the single steps into the system)
According to cognitive science. How does thinking work ?
- Thinking is the result of mental representations and computational processes that operate on those (part of CRUM)
According to cognitive science. How does behaviour work ?
- Behaviour is the result of mental representations and algorithmic processes that operate on those (part of CRUM)
What is meant by AI ?
- Artificial intelligence
What was one of the first learning technique of an AI ? And by which method was that technique replaced by ?
- Rule based learning = trying to figure out the rules of human behaviour and programming those into a computer -> did not work out since the dynamic of behvaiour and the enviorment is to complex
- Replaced by: deep learning
What is meant by deep learning ?
- complete opposite of rule based learning
- feed a bunch of data to data structures that are modelled on the human brain
- The computer learns based on that data
- Needs a set of alogorithm which incodes the data and are based on neural networks
What is the defintion of an AI ?
- It is a system that is capbale of intelligent behaviour by anlyzing their enviorment and taking actions with some degree of autonomy to achieve a goal
Why is AI sometimes superior in decision making ?
- Since AI works highly rational
- Choose the best action in order to achieve a goal
How does an AI execute an action ?
- Perceives enviorment trough sensors -> knowledge
- Reasons based on given knowledge (interpretation and prediction)
- Decision making
- Action via actuators (hands)
What i meant by Rational AI ?
- An AI system which does not adapt behaviour over time
- They do not learn
- Still make rational choices
What is meant by Learning rational AI ?
- evaluates actions to adapt reasoning rules and decision-making methods (Aka learning)
- Rational decision making
What is meant by General AI system ?
- Can perform most activities which human can perform
What is meant by Narrow AI system ?
- can perform one or few specific tasks
What is meant by Black box AI ?
- makes accurate predictions but can’t trace back the reason for certain decisions
Why is deep learning so important for decision making ?
- It allows AI system to solve problems which can not be specified/ whose solution method can not be described by symbolic rules
What are some of the unique features which AI system can learn due to deep learning ?
- speech, language understanding and behaviour prediction
What are other ways of learning regarding AI systems ?
- Reinforcment learning
- Supervised learning
How does Reinforcment learning work ?
- AI system is free to make decisions, but only good ones are provided with a reward signal
- used for ads
How does Supervised learning work ?
- instead of giving behavioural rules to the system, we provide it with examples of input-output behaviour, hoping that it will be able to generalise from exampls
- also should work in situation where no input was previded
- So basically both input and desired output data are provided (teacher) but those are in different context so it should generalize from those
How does deep learning improve/learn?
- contains units with connections between
- Via training you adjust the weights of the connections
