- 5What is the formal difference between the player and the agent in game theory?I am considering the relation between a player and his agent or agents in definition of the game.
yes there is formal difference between "player" and "agent".
i dont remember the paper but Binmore et al call "player" in a game and "agent" in population. that's indeed a fundamental difference.
a game is an abstract context, for example, in PD, there are 2 players (2 prisoners)
if we simulate a population playing this PD game, the machines/automata in the population are called the agents.Following
- 5Except for the Frame Selection Theory of Esser and Kroneberg, are there any other attempts of unifying Schütz' Theory and Decision Theory?
I'm looking for theories or models which try to combine or to unify the theory of Alfred Schütz with common theories of explaining action via decision models like Rational Choice or Bounded Rationality models. The Frame Selection Theory of Hartmut Esser and Clemens Kroneberg is well known to me but I wonder whether there are similar but independent attempts.
the thing is phenomology is to study "how a group of individuals come together and interact". (like network, complexity)
bounded rationality, rational choice is decision theory at the level of individuals.
they dont really need to be "unified" if you mean blending them together. they survive separately because they operate at different levels.
for example, evolutionary game theory studies how a population of (bounded or unbounded) individuals evolve over time.
ps. why is there so few google results on "frame selection theory"Following
- Mohamad Amin Kaviani added an answer:7Fuzzy decision making, Intuitionistic Fuzzy decision making or Grey decision making method- which one is more applicable?
I was thinking about the different decision making methods under certain and uncertain conditions. My specific question is that:
As you know, we have many MCDM tools like AHP- ANP- TOPSIS- VIKOR- PROMOTEE- MOORA- SIR and many other methods and all of them have been developed to fuzzy, type-2 fuzzy, intuitionistic fuzzy and Grey environments. But when we deal with uncertainty, we actually do not know which one of the aforementioned conditions is more appropriate. Which one really more applicable under uncertain situation? fuzzy ? type-2 fuzzy? Intuitionistic fuzzy? or Grey environment for a decision making method?
All the ideas and comments are appreciated. Hope that all of the experts take an action to this question by following or leaving their valuable comments.
I am so happy that my question has been taken into your considerations. I think the subject of this question can push out the frontier of uncertain decision making researches and is a challenging topic.Following
- 5Does anyone know of a quick way to create the illusion of free agency in an experimental setting?
I need a quick way to get participants to think/act as if they have made their own choice, while actually have their choice correspond to their assigned condition. In other words, I am looking for a way to get them to "choose" their assigned condition.
I am considering offering multiple choices (out of 4) and telling them that their choice has to match a random selection in order for the task to begin. But wondering if there is a better, more efficient way to do this.
This is deception. I think deception is outright forbidden in experimental economics?
But psychologists are fine with deception. Let some psychologists in. (I've heard so).
Anyway, making people choose the condition we want messes with their mental mind. Maybe it affects their behavior, though unconsciously. Anyway, if it's just for the unimportant beginning, maybe it's fine.Following

- Elisa Battistoni added an answer:5How to get a limit matrix from weighted supermatrix in ANP(Analytical Network Process) ?
I have a weighted supermatrix and I am trying to convert it into a limit matrix.
Weighted supermatrix can be transformed into the limit supermatrix
by raising itself to powers until the matrix converges
How it can be performed ?
The weighted supermatrix comes out from the combination of the unweighted supermatrix and the control hierarchy. The latter scores the priority of a cluster over all the clusters to which it is connected: therefore, the control hierarchy is an n*n matrix, with n=number of clusters in the network. To build the control hierarchy matrix, first of all you choose a cluster Ci. Then, all other clusters connected with Ci are pairwise compared (with AHP) to determine their impact on Ci; their weights are listed in the control hierarchy matrix. For all the clusters that are not connected to Ci the corresponding element in the control hierarchy is set to 0.
Now, all elements in the block corresponding to the intersection between cluster Ci and cluster Cj in the unweighted supermatrix can be multiplied by the weight of Ci over Cj listed in the control hierarchy matrix. In this way, you can obtain your weighted supermatrix.Following
- Wald Koczkodaj added an answer:7In Analytical Hierarchy Process Is there a way to justify CR>0.1?
I conducted AHP using 3 pairwise comparisons. Unfortunately the CR comes out as 0.302. A balanced scale using principal eigen vectors also results in a CR of 0.22. Is there any way to be able to move forward with these results?
Seyed, I highly recommend Section 5 in:
and text before conclusions.
They show that even CR<0.1 does not guarantee since CR is mathematically WRONG and its creator is aware of it. Counterexamples show that CR tolerates errors of any arbitrary value (e.g., 1,000,000%+). It has recently generated controversy on the international level:
since the eigenvector method has not solved the Middle East problems.

- Devendra Swami added an answer:6Does anyone have an example of a query used to consult experts in the aim of the Analytic Hierarchy Process?
The Analytic Hierarchy Process - AHP (Saaty 1980) is a multicriteria tool considered to be relevant to nearly any ecosystem management application that requires the evaluation of multiple participants or complex decision-making processes are involved (Schmoldt & Peterson 1997, Schmoldt et al. 2001, Reynolds & Hessburg 2005).
A need to consult an example of a form used to be filled by experts in a given area of knowledge in order to perform a pairwise comparison between environmental criteria that are useful to define the soil suitability of a region (e.g., soils, slope, aspect, clima,...). Two factors are compared using the rating scale which ranges from 1 to 9 with respect to their relative importance. Than we obtain the weights for each criteria that will be used in the map algebra.

Probabilities for predicting markets are difficult for an ordinary individual to know. Too many variables influence markets, including manipulation.
In decision making, rationality is subjective to a certain extent. If we have a set of decision criteria, a decision within that framework may appear to others as irrational if they are operating with different criteria. Examples can come from risk/reward scenarios.
Consider the following problem. Two drugs are used to treat intense pain. One drug has a high probability of providing a moderate decrease in pain, which still leaves some residual pain that interferes with normal abilities. No one dies from using it. A second drug provides a dramatic reduction in pain to almost normal (zero) levels but proves fatal to 1% of the population that uses it. Which drug choice constitutes the rational decision? It depends on your decision criteria. Whereas it is true that one cannot predict exact individual outcome from analyzing data obtained in past studies, one can use published probabilities if they exist. Suppose you want to maximize the probability of living and are willing to live in a debilitated state. If this is the most important decision criterion, select drug A. If, however, you would not like to live in such a condition and would rather try for a better life, and this is the most important criterion, select drug B. Each of the decisions appears to be irrational when applying the opposite criterion. However, the decisions are rational given the criteria used.
To consider another example, what constitutes a rational decision can depend on habits and experience. A decision about what to do in an emergency situation may seem rational to a novice who may be more likely to be influenced by emotions. However, to a person with more expertise, the same decision may appear to be irrational because the expert has more knowledge and experience and is aware of more options.

Hello, I have a large corpus of product reviews given by customers, especially on mobile phones. I have done a topic modeling on this data so that the topics are extracted.

Is there any tools available for the same or do I need to classify manually ? Please help in this regard.
Hi, this looks like normal machine learning issue.
You need to define features which are somehow related to your aspects. Features can be something like - "how many times word CAMERA is nentined in the article" etc.. Then you label training data set with both features and aspects. Then you can build decision tree classifier which assignes aspect depending on features.

- Carlos R. B. Azevedo added an answer:4Are the decision-theoretic accounts of Preference for Flexibility and Freedom of Choice being applied outside economics?The ﬁrst axiomatic accounts of preference for ﬂexibility and freedom of choice are due to Koopmans (1962) and Kreps (1979), who assumed that a Decision Maker always enjoys having more alternatives available. After that, e.g. Puppe (1996) refined the idea and distinguished the essential alternatives in an opportunity set as those whose exclusion “would reduce an agent’s freedom”.
Most applications I know of consider social choice problems that are relevant to economics theory. What other fields have seen applications of those concepts? I'm particularly interested in corporate decision-making and engineering design.

- Harald C Traue added an answer:1How were ethically relevant cognitive biases within the test population controlled?
The test population was self-selected from a sub-population (the Amazon Mechanical Turk subscriber base) which is significantly unrepresentative of the US population generally (which is itself highly heterogeneous). According to Wikipedia(for what it's worth) "Overall, the US MTurk population is mostly female and white, and is somewhat younger and more educated than the US population overall." Your test populations were, however, generally less than 50% female (just over that in study 2) and there were some significant screening tests applied, including such things as attentional deficits, rapid test completion and so on, which excluded high proportions of respondents (up to around 25% in study 3). I may be mistaken but I didn't notice any discussion of measures to control for culturally/socially/educationally normative cognitive biases that may skew the responses of such selectively filtered sub-populations compared to a more representative sample?
In addition, while I can understand the purpose of the screening was probably to facilitate selection of a test population of intentional responders, rapid response may not be negatively correlated with intentionality. It may reflect a previously well-considered ethical framework, or a cognitive bias derived from religious or other convictions, and there are other possibilities.
Two other factors I would have thought may have been considered significant, especially in light of the work of Kohlberg and latterly Gilligan, are age and gender. Was any consideration given to these factors?

JP 3-0 Joint Operations (11 Aug 2011) at url http://www.dtic.mil/doctrine/new_pubs/jp3_0.pdf describes Freedom of Action as:.
"The JFC must maintain freedom of action throughout the operation. Of necessity, freedom of action must extend beyond the JFC’s operational area. For example, operational reach—the distance and duration across which a joint force can successfully employ military capabilities—can extend far beyond the limits of a JFC’s JOA and is inextricably tied to lines of operation (LOOs). So the joint force must protect LOOs to ensure freedom of action. Likewise, the C2 and intelligence functions depend on operations within cyberspace. Losing the capability to operate effectively in cyberspace can greatly diminish the JFC’s freedom of action. While various actions (such as computer network defense [CND] and the consideration of branches to current operations) contribute individually to freedom of action, operational design and joint operation planning are the processes that coherently link these actions. Thus the JFC and staff must consider freedom of action from the outset of operational design and must be alert to indicators during operations that freedom of action is in jeopardy."Following

For instance, the visual quality of a forest depends on attributes as the size of the trees, the density of the forest stand, the diversity of species, and the diversity of distinct heights. There are preference dependencies among these attributes.
