Class 5 - Communication Flashcards
Language Communication can involve…
signs
touch
verbal cues
gestures
3 reasons why we would argue that Pepper (the robot shown at the beginning of the class) does not really understand language (although it can produce it)…
- lacks physical experience in the real world
- lacks incremental social learning –> we learn incrementally from when we are young, robots get all the information together
- lacks true understanding of the world –> does it actually understand what it is talking about?
T/F: In the classical AI approach (before the Symbol Grounding problem came around), only the symbol and the meaning were part of the “equation”
True
Symbol grounding problem in the context of AS
- certain concepts, symbols, those are symbols of a system, and these symbols are only meaningful for an external observer.
- symbols must be grounded in robot-environment interaction
In their Physical Symbol Grounding semiotic triangle, Vogt et al. included these 3 components: which ones?
one Symbol
one Meaning
one Referent
Two attempts (one the continuation of the other) to solve the Symbol Grounding problem
- Physical symbol grounding
2. Social symbol grounding
In their Social Symbol Grounding semiotic triangle, Vogt & Divina included these 4 components: which ones?
one Symbol (the word spelled out)
two brains, hence two Meanings (the two brains belong to the two people / robots interacting and both brains contain a meaning related to the symbol)
one Referent
T/F: The form of the word doesn’t matter if we talk to ourselves, as long as we know “what we’re talking about” in our head
True
T/F: if we are interacting with someone/with a robot, we need to use words we both understand, hence we have to learn the same relation between the Symbol and the Referent
True, this allows us to follow the conversation
T/F: Simple skills can be used to learn more behaviors
True
Will robots learn to communicate with each other in this cases? (Yes/No) for each possibility:
- homogeneous robots + fitness calculated for the whole group –> Y/N?
- heterogeneous robots + fitness calculated for the whole group –> Y/N?
- heterogeneous robots + fitness calculated per individual –> Y/N?
Yes
Yes
No
Deceptive communication between robots
Each robot doesn’t learn how to gain points & doesn’t learn how to use its output signals to discuss with the others how to gain points in a game together as a team
T/F: As new generations of robots are created, the strategy to achieve a certain reward together can change / get updated by reusing the old skills
True
T/F: As new generations of robots are created, the old skills tend to be forgotten / deleted
False, they tend to be preserved and most likely improved
T/F: In a Multi-level organization, sub-behaviours work together
True
